    Mar 2013

    spmaoThe Structural Pest Management Association of Ontario (SPMAO) is a partner with The Canadian Pest Management (CPMA) and the National Pest Management Association in the USA.( NPMA)

    The SPMAO  work hand in hand with Ontario Member Pest Management Companies to assure adherence to Ministry of the Environment Regulations as well as proper and ethical Pest Management Practices within our industry.

    SPMAO is hosting a Pest Management Conference at The Westin Harbour Castle, in Toronto on March 20-21-22 2013 in Conjunction with the NPMA.

    Many industry experts will address our membership, and it promises to be a very informative conference.

    This conference is just one in a long line of conferences I have attended over the course of my career as a Pest Management Professional, but each one is a unique experience and will add another learning notch to my belt.

    In a few weeks, look to this blog for new updated and information gleaned from my experience at this event.

    Hope the advent of Spring finds all Pest Free, but if not please call me and I will be happy to assist you in becoming just that.

    Bed Bugs

    Having problems with bed bug infestation? Getting bed bug bites at night? Afraid that there are bed bugs hiding in your mattress? You are not alone on this issue.

    A recent Bugs Without Borders survey found that 99 percent of Professional Pest Management Companies have encountered a Bed Bug infestation in the past year.

    There is no doubt that Bed Bugs are here for the long haul.

    Continual Bed Bug eradication studies show the common Bed Bug to have high resistance to all Pyretheroids which are the only chemicals currently registered by both the EPA (USA Environmental Protection Agency) and the PMRA (CAN., Pest Management Regulatory Agency) (more…)

    Our most common calls for cockroach removal in and around Hamilton, Burlington, Kitchener, Oakville, and Cambridge are to get rid of the German Cockroach which is the most prevalent species infesting Ontario homes, restaurants, offices and other commercial premises.

    Horrid Facts about German Cockroaches

    • They like to feed off your toothbrush (yes, cockroaches can actually survive off toothpaste)!
    • They also love to eat glue – the kind that holds cardboard boxes together!
    • If you see them active during the day you already have an infestation that is getting out of hand and need to take action pretty quick!
    • Every female cockroach can produce up to 500 offspring per year – just do the math and you will soon see why cockroach infestations need fast, effective action to get under control.

    Threats to Health

    German cockroaches are believed to be responsible in part for outbreaks of food poisoning, diarrhea, dysentery and other gastroenteritis-type illnesses and allergic reactions. The bacteria that cause these kinds of diseases are carried on their spiny legs and bodies as they scavenge for food and then are deposited on the surfaces with which they come into contact.
    In addition, cockroach feces and shed skins are known to harbor allergens that affect many people, casing sneezing, nasal congestion, rashes, watery eyes, skin rashes and even asthma.


    Cockroaches prefer to nest in cracks and crevices in ceilings, floors, bathroom and kitchen cabinets – in just about any location that offers a safe, dry spot in which to wait out the daylight hours until it’s time to feed.


    They usually feed at night but if no food sources are available they can go without eating for up to a month with no apparent ill effects (so long as they have access to water). They’re often accidentally carried into homes and other premises in contaminated containers such as the cardboard boxes in which cockroaches like to live.

    The females are very attentive mothers and carry their 1 cm big monthly egg capsule around for up to 48 hours before it hatches into about 40 wingless nymphs. These quickly seek shelter in dry crevices where they survive and thrive feeding off cockroach droppings and shed skin. Nymphs mature at different rates within 2-7 months, depending on available food sources, warmth and humidity.

    OHN Pest Management Services’ cockroach removal technicians are skilled in exterminating the adult cockroaches as well as the nymphs and eggs that may remain hidden in crevices and can go on to re-infect your Hamilton, Cambridge, Kitchener-Waterloo, Oakville, Burlington and other Ontario premises if not adequately dealt with.

    Rattus Norwegicus or Norway Rat was introduced to North America by early European sailors.

    Today they inhabit every North America City and Countryside.

    Rats are burrowing animals and will live in holes in the ground around their food source.

    They are also known to inhabit the sewer systems of all major cities, sometimes appearing in homes via the toilet.

    Rat control is a specialty and the biology and feeding habits must be understood for proper elimination.

    Carpenter Ants

    Carpenter Ants are a unique species of ants which excavate wood to make their homes.

    In nature their function is to help in the rapid deterioration of old decaying trees, but unfortunately these ants can not distinguish between a dying tree and the water drenched edges of your soffits  and/or  Patio Doors. So they could cause damage once they get into your house. (more…)

    Indian Meal Moths

    The Indian Meal Moth is the most common of stored product pests.

    The adult moth is about 1 centimeter long, grey on the lower part of body with distinctive yellow/tan markings on the upper parts.

    Immature or larvae of this moth is white and can be observed crawling up wall areas where it is looking to find a ceiling area to pupate in, leaving small cocoon’s in the wall/ceiling joint.

    Indian Meal Moth will infest most meal type foods including Rice, Oats,Corn,Nuts, and many others. Wild Bird Seed and dry pet foods are particularly prone to infestations.

    Most Stored Product Pests can be monitored with Pheromone Traps and Lures which OPM can supply.

    Eradication of these pests require thorough preparation procedure and control methods.

    Although commonly found in wooded areas, ticks can be found pretty anywhere because they are carried by the birds and other animals they feed on.

    In Canada, we have approximately 40 species, but fortunately for us humans, only a few of them can transmit Lyme disease.

    Common ticks in Canada

    Below is a quick guide to some of the most common ticks in Canada.

    Carpet Beetles

    The Varied Carpet Beetle and the Black Carpet Beetle are the most common Carpet Beetles found in the Ontario environment.

    The Varied Carpet Beetle has a distinguishing mottled white and dark back and the Black Carpet Beetle is as the word implies uniformly black in color. The adult beetle in both cases are about 3mm long and roundish. The larva, which is the destructive part of this insect is up to 3-5 mm long and has fuzzy hairs on its body, the tail is tapered to a point.

    The adults of the species of both beetles are feeders of plant juices, but the larval stage of these insects will feed on and infest a number of natural fabrics such as wool and cotton as well as horse hair and natural fur and hide.

    The home owner will often find the small brown to yellow fuzzy larva crawling along edges of carpeting and baseboard, as well as in dresser drawers with natural wool swea.

    It can take 249-354 days to three years for varied carpet beetles to grow from an egg to an adult.

    The three most poisonous species of spider in Ontario are the black widow, the yellow sac and the brown recluse.
    Black widow spiders

    Black widows are actually rare in Ontario but they are by far the most toxic and bites from any one of the five species that exist in our province can result in hospitalization and will even be fatal in 1% of cases. The most recent reported cases of black widow sightings in the last few years occurred in Port Hope, Oakville, Mississauga and Bolton.

    Black widow venom is a neurotoxin that can almost instantaneously affect the nervous system, causing victims to sweat profusely and experience raised blood pressure, fever and blurred vision.

    Most bites occur while people are out working in their back yards as they garden or remove the piles of firewood and brush that black widow spiders like to nest in. They also like secluded garages, basements, crawl spaces and other areas where they are generally left undisturbed.

    How to identify a black widow spider


    They are small, shiny black in colour with red markings shaped like an hourglass on the underside of their abdomen. An adult black widow only measures about the size of a paper clip.

    Yellow sacs

    This species of pale yellow spider is notable for its darker coloured fangs and cocoon-like webs. In southern Ontario they like to spend the warmer spring and summer months nesting in and around porches and decks and then migrate inside during the winter months. They are nocturnal creatures, coming out to hunt for insect food at night. Their bite is very painful and can cause swelling and blistering.

    Brown Recluse

    This spider can easily be identified by the violin-shaped markings on its thorax – hence its nickname ‘fiddleback’. It doesn’t actually live in Ontario but is occasionally transported in from warmer southern climes in shipped-in goods such as fruit and vegetable containers.

    Brown recluse bites cause intense pain, fever, swelling, blistering and necrosis – ie, they can make your flesh rot. Although not usually fatal, brown recluse bites can take up to two months to heal and are extremely painful.

    To find out more about Ontario’s poisonous spiders, go to:

    All this being said, most of Ontario spiders do not pose a huge danger to people and are actually beneficial, playing a vital role in the ecology by eating other insect pests and helping to pollinate plants and trees. They are also an important source of food for other wildlife such as birds, small mammals and fish.

    Interesting spider facts

    • Spiders are part of the Arachnid family which is comprised of more than 30,000 species.
    • Most spider species have either six or eight eyes.
    • However, despite their large number of eyes, many spiders are short sighted. They rely on their hairy bodies to sense when predators lurk nearby and to feel their way around.
    • Not every species of spider spins webs. Only those that have spinnerets (specialized spinning glands located at the end of the abdomen) can spin webs.
    • Spiders often replace their webs on a daily basis – or whenever they get torn or dirty. They recycle the old web silk by rolling it into a ball and eating it!
    • Most spider species have fangs through which they eject their venom.
    • They are oviparous – ie egg laying creatures.
    • Spiders are not insects. They have 2 body parts (the thorax and the abdomen) and 8 legs, compared to the 3 body parts and 6 legs of insects.
    • Females are usually larger than males.
    • Sometimes spiders are confused with opiliones (also known as harvestmen, harvest spiders or shepherd spiders) which are harmless to mankind, have no venom, fangs or spinning glands and are often seen during the summer harvest (hence the name).
    • Fear of spiders (Arachnophobia) is one of the most widespread animal phobias in humans.

    Flea bites can drive you mad with itching that goes on for days and apart from leaving you with that tell-tale line of raised red spots may even cause an allergic reaction in some people and transmit parasites (dog tapeworm) or even some diseases.

    Fleas are usually found in homes where there are pets such as cats and dogs. However, they can also be carried inside on clothing or young fleas may enter homes from old rat dens, bird nests and other animal lairs in their search for new blood hosts.

    If you suspect you have a flea problem it is good to get them removed as soon as you can to stop the infestation getting any worse. Fleas breed rapidly and if the conditions are warm and humid enough, within 2-3 weeks will already have produced a second generation and your flea problem will rapidly escalate from there.

    The fleas that you actually see are only about 5% of the actual population. The other 95% are the nymphs and eggs that are just waiting for the right stage in their life cycle to begin to bite. So deal with your flea infestation as soon as you notice it.

    We have found that the most common species of flea in homes in Hamilton, Burlington, Oakville, Kitchener-Waterloo, Cambridge and other Ontario locations tend to be cat fleas which, despite their name, are also found on rodents, dogs and people too!

    All fleas have very strong legs that enable them to jump as far as 16 inches in a horizontal direction and up to 8 inches vertically. They prefer to remain on the bodies of their host where there is always a warm blood meal available whenever they need. However, you may also sometimes see them jumping around on blankets, rugs, trouser legs, shoes and other objects – which is one way that fleas are transmitted to new surroundings. Fleas from outdoor wildlife such as raccoons, opossums, skunks and other backyard urban pests are usually carried into homes and offices in this way.

    Threats to human health


    Fleas are the main carriers of bubonic plague although it is now rare in the developed world. They also carry endemic typhus from infected rats and other carriers. This can cause nausea, vomiting, fever, joint and muscle pain as well as a measles-like rash in some patients, and even neurological symptoms including imbalance, confusion and seizures.

    In pets, flea saliva can trigger Flea Allergy Dermatitis which causes chronic scratching leading to bald patches and skin lesions. They are also the cause of anemia and may even transfer tapeworms to pets too.

    How Hamilton’s OHN Pest Management can help with flea removal

    There are four stages in the flea life cycle:


    1. 1. Females lay eggs on the host animal which fall to the ground and hatch in 12-14 days.
    2. 2. The new born nymphs crawl into cracks, to the base of carpet fibres, under sofa cushions and into other protected places where they feed off the partly digested blood that adult fleas leave behind in their faeces, and other organic matter.
    3. 3. Within less than two weeks after birth, the nymph spins itself a cocoon and becomes a pupa – a stage in which it can remain for five months or so. We still don’t quite know what triggers the emergence of the adult flea – it could be vibrations or the presence of increase levels of carbon dioxide which indicates to the pupa that a new host animal and a fresh source of blood has become available.
    4. 4. Emerging adult fleas need to feed off fresh blood within two days after emerging if they are to survive. Two days after their first meal, adult females are already capable of breeding and will continue to lay eggs for 3-4 months. A single female can lay 500 eggs during her lifespan.


    So an adequate programme of flea removal needs to eliminate fleas at all four stages of their life cycle.

    Our experienced team at OHN Pest Management has exterminated fleas from residences and commercial properties throughout
    Hamilton, Cambridge, Kitchener-Waterloo, Oakville, Burlington, and other Ontario locales.

    Silverfish can eat through your clothes, books, wallpaper and other paper goods before you know it.
    They love glue and other starchy foods such as rolled oats and flour.
    Small, shy and nocturnal, they can easily go unnoticed until the damage is done!
    If you find you are having problems with silverfish in your bathroom, basement, attic or other humid indoor environment, call OHN Pest Management and removal services.
    We have eliminated silverfish from homes and businesses throughout Ontario, including locations such as Cambridge, Burlington, Oakville, Hamilton, Kitchener-Waterloo, and other locations throughout Ontario.

    Telephone 1 888 500 2156 or 289 237 1062 today or email us at to find out how we can remove your silverfish infestation and help with other animal pest problems.



    These insects are named after their metallic, silvery looking appearance and fish-like movements and shape. They measure ½” – ¾” in length and have delicate, wavering antennas.

    Silverfish can run extremely fast, are nocturnal, and will quickly hide as soon as they are disturbed. This means that often you will only notice that you have a silverfish infestation once the damage is done and you see that your wallpapers, books, boxes, cereals, flour, oats and other starchy substances have been eaten away.

    They also feed of clothes and other natural fiber fabrics that satisfy the requirements of their protein-based, high carbohydrate diet. However, silverfish can also survive for up to 12 months without food so long as they have a high humidity location in which to hide

    Threats to human health


    Silverfish are more of a nuisance rather than an actual health threat although they will contaminate foodstuffs that they succeed in getting into.

    Life cycle

    Silverfish hatch out of eggs that are laid by adult females in clutches of 5-50 eggs at one time. After hatching, they moult several times over the course of three years before they reach maturity. After this, they can survive for another three years as breeding adults so long as they have a constant food and water source, making them among the most long-lived of insect pests.

    Silverfish breeding grounds are extremely difficult to locate – which is why they can be hard to exterminate. Our pest removal experts at OHN Pest Management know exactly where to look and how to safely apply the chemical substances necessary for getting rid of silverfish at all stages of their growth cycle. We can also advise on how to prevent new silverfish infestations in the future.

    To find out more about our silverfish removal services, please phone 289 237 1062 or 1 888 500 2156 or contact us by email at

    Pavement Ants

    OHN Pest Management are skilled in removing pavement ants from homes and commercial properties in and around Hamilton, Cambridge, Oakville, Burlington, Kitchener-Waterloo and surrounding areas in Ontario.

    Call us on 289 237 1062 or 1 888 500 2156 to find out more about our pavement ant extermination services. Or contact us by email at to request a free estimate.

    Pavement ants


    These little black ants are a familiar site scurrying around our yards and along driveways from spring on into the early days of fall. They are responsible for making those small heaps of soil and dirt that you sometimes see on the edge of pools, patios, walls and in other places where they can seek shelter and food. As long as there is a good supply of water, pavement ants can set up home in pretty much any kind of crack – hence their prevalence in every back yard.

    Pavement ants feed off whatever they can find – left over pet food, sugar, cheese, honey, insects, aphid secretions, bread and other crumbs – they are voracious foragers. Once they discover a food source they quickly establish a trail and will repeatedly come back until the food supply is eliminated.



    Pavement ants do not really pose any real health risk per se and are more of a nuisance than anything else. However, before you decide to do nothing you should double check that they really are pavement ants because other ant species can cause widespread damage to your property and may spread disease and pathogens into your home.

    At OHN Pest Management we have found that the most effective way to eliminate pavement ants for good is to get rid of the entire colony. Our expert exterminators know exactly how to place effective, tamper-proof, poison baits so that the worker ants carry venom back into the heart of the colony and they die from within.

    This may take a little while longer to eliminate the infestation than with an aerosol spray for example, but you can be sure that you have exterminated all of the colony and their eggs and that no small satellite groups remain to breed anew.

    Ant bait is very toxic, however, and can be dangerous to pets, small children and anyone else who comes into contact with it – which is why it may be wiser to call in a professional pest removal company like us.

    We have exterminated pavement ants at numerous properties throughout Ontario, including homes and places of work in Burlington, Hamilton, Oakville, Kitchener-Waterloo and Cambridge.

    For more information about our pavement ant and other pest control services, please call OHN Pest Management on 1 888 500 2156 or 289 237 1062 or email us at for a FREE estimate.

    Have paper wasps chosen your property as the site of their hanging comb nests?
    Do you find wasps buzzing around your porch when you want to go inside?
    Does your cathedral ceiling have a tell-tale paper wasp comb hanging down from the high point?
    Our experienced and professional paper wasp removal experts at OHN Pest Management services have exterminated paper wasp nests from both inside and outside residences and commercial properties throughout Hamilton, Burlington, Kitchener-Waterloo, Oakville, Cambridge and other surrounding Ontario locations.

    Telephone 1 888 500 2156 or 289 237 1062 or email us at to schedule your paper wasp removal service or for enquiries about how to get rid of other unwanted animal pests.

    Paper wasps, or umbrella wasps as they are also known, are named after the paper-like material from which they make their honey-comb, open-celled, umbrella-shaped nests.

    They are generally non-aggressive and usually only sting when attacked or if they feel threatened in some way. However, their sting is as painful as any other wasp or bee sting and can cause the same type of allergic reaction in susceptible people.

    The main problem with paper wasps is that they like to hang their umbrella shaped combs from roof soffits, porch ceilings, eaves, the tops of window and doorframes, rafters, railings, deck floor joists and entrance ways where people have to pass, so they can be difficult to avoid.

    How to recognize paper wasps


    Paper wasps are slender, brown and yellow or reddish brown in colour, measuring ¾-1 inch in length with slender waists and charcoal coloured wings that they fold against their bodies when not flying. They feed off insects such as caterpillars and flies, and also seek out nectar.

    They live in small, semi-social colonies of around 20-30 adult workers and a single queen who lays eggs throughout the summer until temperatures start to cool. The workers then die off and the young mated queens seek sheltered crevices such as under tree bark or in cracks in buildings in which to overwinter and wait out the warmer days of spring when they emerge to start new colonies. It is during the cooling days of fall that a newly inseminated queen may make her way indoors and later start her nest hanging from your cathedral ceiling.

    If you are facing problems caused by paper wasps or any other pests, OHN Pest Management will be pleased to assist. We have spent the last 30 years helping to remove unwanted animal guests from homes and commercial properties in Kitchener-Waterloo, Burlington, Cambridge, Hamilton, Oakville and many other locations in Ontario province.

    Deer Mice

    We can assist with Deer Mice removal in Hamilton, Burlington, Oakville, Cambridge, Kitchener-Waterloo and other nearby Ontario areas.

    Beware – although very ‘cute’ looking, deer mice can carry potentially fatal diseases and for your own health and safety you need to get rid of them as soon as you can, as well as decontaminate any areas in which they have been nesting.

    Threats to human health


    The problem with deer mice is that they can transmit the potentially fatal, incurable Hanta virus. This pulmonary syndrome is usually passed to humans who somehow come into contact with dead mice, mouse feces or who breathe in vaporized drops of urine from an infected deer mouse.

    They can also spread Lyme disease and are known carriers of Ehrlichiosis (a bacterial, tick-borne infection) and Babesiosis (a parasitic blood disease with similar symptoms to malaria).

    What to do if you think you have a deer mouse infestation
    Due to the potentially fatal consequences of the diseases that deer mice carry, it is wise to call in an expert deer mice removal team immediately.

    Our skilled team at OHN Pest Management has the experience to remove your deer mouse infestation and to organize the type of thorough decontamination that is necessary to remove all traces of urine, feces and deer mouse carcasses.

    How to recognize deer mice


    You can recognize deer mice (Peromyscus) by their big eyes and ears, white feet and under-bellies and long tails. They get their name because they are very agile and can jump and run fast like deer. Deer mice measure about 2-3 inches long and can live for up to five years – making them one of the most long-lived of mice species.

    Deer mice generally avoid areas that are densely populated such as cities and large towns so it is rare to find deer mice in residences or other buildings in urban areas although they will invade rural houses when they get the opportunity. When they are occasionally found inside, it is usually in a quiet, undisturbed part of the house such as the attic.

    However, they usually prefer to make their nests outside in sheltered piles of debris, hollow tree logs, in abandoned animal lairs, under brush or in any similarly protected habitat.

    At OHN Pest Management Services we have wide experience removing deer mice from both inside and outside properties in Burlington, Hamilton, Oakville, Kitchener-Waterloo, Cambridge and other nearby Ontario areas.

    Contact us today on 1 888 500 2156 or 289 237 1062 or email us at to find out how we can help you with deer mice removal and other pest problems.

    Oriental Cockroach



    Oriental Cockroaches (Blattaorientalis (L.)) are those large, shiny, black or dark, reddish-brown, beetle-like cockroaches that you often see emerging from drains and sewers throughout Hamilton and Ontario.

    They are sometimes known as water bugs because they are usually found wherever there is decaying, wet, organic material.
    Females are larger than the males, measuring 1 ¼ inches compared to the males’ 1 inch in length. Males, however, have longer wings that may reach ¾ of the way along their abdomen whereas females have only short, stubby wings.

    Eating Habits


    Oriental cockroaches feed off the decaying sewage and other organic matter in which they like to live.


    One of the oriental cockroach’s favourite habitats is the sewage pipes that run below the surface of Ontario’s towns and cities and provide the type of cool environment in which they like to live.

    They enter human structures through the drains found in basement and bathroom floors and then start to nest in crawl spaces, rough basement walls and other suitably cool locations. Here they lay their egg casings (known as Oothecas) which hatch when the ambient temperature is right – which can vary from just a few weeks to up to several months later. The emerging nymphs then start to forage for food and set up their own nests, and so the cycle continues.

    Threats to Human Health

    Like all their species, oriental cockroaches harbor numerous types of bacteria, worms and other pathogens that can have a noxious effect on humans. Oriental cockroaches in particular are known to spread more than 33 different bacteria, are host to at least 6 parasitic species of worms and carry 7 or more pathogens that are harmful to man.

    Most of these pathogens are picked up as they crawl through the sewage and other decaying material in which they live. The bacteria, pathogens and worm eggs stick to their bodies and their spine-covered legs and then are deposited on food or other surfaces with which humans come into contact.

    Other germs enter the cockroach’s body in the rotting materials that they feed off. The cockroach provides a perfect environment for these pathogens to breed and stay infectious for up to several weeks longer than if they had remained outside in the sewer where they would come into contact with sun, air, detergents, chemical and other non-germ friendly mediums.
    Recent research suggests that cockroaches may be both a cause of asthma and part responsible for the increase in allergic reactions that has been noticed in children living in inner cities. It is believed that these allergens accumulate in the feces, shed skins, dead bodies and bodily secretions of oriental cockroaches.

    OHN Pest Management offers oriental cockroach removal by experienced technicians who are skilled and practiced in getting rid of both the adults and the eggs and nymphs that would otherwise hide away in cracks and crevices to re-infest you sometime in the future.

    If you live in Hamilton, Kitchener-Waterloo, Burlington, Cambridge, Oakville or elsewhere in Ontario premises and would like to know more about our cockroach elimination programmes, give us a call on 289 237 1062 or 1 888 500 2156 or email us at

    Pharaoh Ants

    Are pharaoh ants making your life miserable? OHN Pest Management can help. We are experts at exterminating pharaoh ants and other insect pests from both inside and outside homes and commercial properties throughout Ontario, including the Oakville, Burlington, Kitchener-Waterloo, Hamilton, Cambridge and other nearby areas.

    Call us on 1 888 500 2156 or 289 237 1062 to find out more about our pharaoh ant removal service.
    Or email us at for a FREE estimate.

    Pharaoh ants are a major pest world-wide because they thrive in, and seek out, heated, indoor areas. Hospitals, for example, often need to take strict pharaoh ant control measures or they will soon contaminate sterile rooms and equipment and rapidly spread disease and bacteria.

    However – beware of trying to get rid of pharaoh ants by yourself!

    This ant species has numerous queens and when you try to eliminate a colony they just pick up their eggs and move elsewhere – creating two or more new colonies in the process. It is a case of divide and thrive.

    When you tackle a pharaoh ant colony you need to be sure of eliminating all the queens and their eggs too, or you could just be creating an even bigger problem. If you spray them they will just scatter and set up home elsewhere. A small group of just 1 queen, five workers and 10 almost-mature adults are all it takes to start off a new colony and your infestation will begin all over again.

    This is why with pharaoh ants it is generally good to call for professional assistance – and Ontario’s OHN Pest Management will be delighted to help!

    Facts about pharaoh ants (Monomorium pharaonis)


    • They are small and yellow with darker (sometimes red) thoraxes (area between abdomen and head). They measure about 2mm long.
    • Workers ants hatch from eggs and mature within a month and a half. They can live for up to 10 weeks.
    • Queen pharaoh ants have a life span of 9-12 months and can lay as many as 400 eggs in their lifetime.
    • Males die within a month or so of mating.
    • They are sweet-toothed but will also feed off other insects and are particularly attracted to kitchens and other food preparation areas.
    • In Ontario and other cold climates, pharaoh ants actually need heating to survive. They like to nest in warm, dark, undisturbed spaces and we often find them behind baseboards, between walls, in fridge insulation, in the folds of unused sheets and stacks of paper – even in the hollows of curtain rods!

    House Mice Removal in the Hamilton, Burlington, Cambridge, Kitchener and Oakville area


    Of all the animal pests we deal with at OHN Pest Management, house mice are one of the most common. Pretty much everyone knows what a house mouse looks like – they are small, light brown or grey rodents, measuring between 6-9 cm in length.

    They almost always infest attic spaces in buildings and then travel down to the kitchen at night in the spaces between wall panels to forage for food. You are most likely to notice mouse droppings and other signs of feeding behind your fridge or on the stove top where food debris is not always cleaned away immediately.

    Most house mice infestations occur as the warmer days of summer give way to fall and the great outdoors no longer provides the kind of hospitable living conditions that house mice need to survive and breed.

    Once warm and comfortable in your attic, the female house mouse is a prolific breeder, producing a litter of up to 8 newborn mice every 5 weeks. The 3-4 females that are born in this litter will themselves reach maturity within six weeks and will go on to produce offspring of their own. Do the math and you can soon see why it is important to get rid of your house mouse guest at the first sign of infestation or you could be in for a great deal of avoidable damage to your belongings and unnecessary risks to your health.

    Mice like to forage for food and their bodies transmit bacteria and other pathogens from garbage to the areas with which the come into contact. They also carry lice, ticks, mites and fleas which bring their own potential health and allergy problems. Mice urine in particular is a known allergy trigger in children.
