Identify What’s Bugging You with Our Visual Pest Library


Rats – The rat most commonly found in Ontario is the brown rat. Also called a Norway rat, the brown rat is typically found in humid environments closer to the ground. Most rats are known for damaging wiring, food, and valuables by chewing, eating, and excreting.


Pigeons - Making nests on roofs, soffits, and business awnings, pigeons are known to nest anywhere they can. The messes they make and the noise pollution they inflict can be unsightly and make your business undesirable. As the only bird we typically encounter, we always attempt to remove their nests humanely when trying to disperse their population.


Cluster Flies – Usually found in groups indoors during the winter, these flies do not pose any health threat but are annoying nonetheless. Cluster flies are often seen in late summer to early fall. They will gather on the sunny side of structures. Cluster flies are similar in appearance, but are slow, sluggish in comparison to the house or blow fly. You will begin to see them show up as the days get shorter and the nights get cooler.


Fruit Flies – Unsurprisingly, fruit flies are usually found in and around the kitchen or wherever fruits, vegetables, and other sugar-rich sources exist. They can exist in garbage cans, compost, drains, and fruit bowls. Removing any food source and dealing with the infestation can be long and tedious as they can easily return.


Cockroaches - There are many types of cockroaches out there, but the main cockroaches we encounter most in Ontario are the German cockroach and the brown-banded cockroach. They are all hardy insects that can live almost anywhere. The German cockroach is small, brown and found in houses and restaurants, these insects can run quickly and can produce 100,000 offspring a year. The brown-banded cockroach is tan to light brown and has two light-colored bands across the wings and abdominal area. The bands may sometimes appear to be broken or irregular but are very noticeable.


Carpet Beetles – Usually brought into the house on plants or flowers, carpet beetles often lay their eggs in air ducts, collected lint, dry dog food, wool, and stored grains or spices. The larvae can cause damage through eating irregular holes in carpets and fabric. Carpet beetles are small, dark brown and will eat a single, large area of a fabric, whereas moths will eat tiny holes all over garments.


Stored Product Pests – Usually in the form of moths and beetles, these pests can make nests in products stored for a long period of time – including dried fruits, nuts, clothing, and more. Their infestation will continue as long as they have an endless food supply. They can be found in kitchens and food warehouse, where they find stored food to lay their eggs in. Specifically, in Ontario we confront Indian meal moths, fabric moths, grain moths, flour beetles, and grain beetles.


Fleas – Minute fleas can live in furniture, carpets, clothing, and any openings or cracks in the wood flooring. Generally living on the blood of our pets, fleas can also often bite human pet owners just as frequently. Watch for signs of flea infestation from pets overly scratching or legions of bumps affected by allergic reactions.


Centipedes & Millipedes – With innumerable legs and long antennae, centipedes and millipedes live in dark and damp areas. These pests actually eat other insects, but can become an unsightly nuisance. Houses with moisture problems can experience an infestation more than any other.

Asian Ladybeetle

Asian Lady Beetles – Usually referred to as “ladybugs”, these beetles can come in a wide variety of colours and markings. Lady beetles can be found in large numbers and are just a nuisance rather than actually dangerous in anyway. Usually seeking damp, warm places, they are prone to infesting houses near woods or fields.


Mice – Where there is one mouse there are many. The most common pest mice in Eastern Ontario tend to be house mice and white footed mice. Mice can severely damage insulation, electrical wiring, and other household appliances. Most mice can fit through the tiniest openings and easily access homes and buildings. With a litter of 2-13 mice per litter, mice are known to be able to breed all year long throughout their short lives.


Wasps & Bees – The most common bee and wasp species we deal with are bumble bees, cutter bees, honey bees, European white-faced hornets, bald-faced hornets, and yellow jackets. Regardless of the different markings and colours per species, these pests can be very dangerous for those with serious allergies to their stings. Bees, wasps, and hornets’ nests can be built in just about any area overhead or even in the soil. Attempting to remove these nests alone can prove to be extremely dangerous and unadvised.


Green & Blue Bottle Flies - Often referred to as a common house fly, the green (or blue) bottle fly is from the blow fly family and is common throughout North America. The female says her eggs in meat and garbage. The maggots produced are commonly seen in compost bins throughout the Ottawa area.

carpenter ants

Ants – Ants of all kinds live and thrive in large colonies. Most ant colonies consist of a few hundred to thousands of workers working under a queen. Ant infestations usually require removing their habitats, traveling paths, and nesting areas in and around a building. The most common ant species found in Ontario are carpenter ants, pharaoh ants, and pavement ants.


Bed Bugs – Bed bugs can cause deep psychological torment as they feed on human blood during sleep, and their bites leave irritating red bumps all over the skin. Bed bugs are shaped like flattened apple seeds and are generally quite small and hard to detect. They can hide just about anywhere in the house and only emerge at night.


Spiders - Most often spiders are generally harmless and only cause psychological distress to homeowners. Even though these eight-legged invaders want almost nothing to do with humans, arachnophobia is a strong fear that exists in most people. Very few spiders actually possess a venomous bite, but spiders like the black widow, although rare, can actually be dangerous.


Woodbugs – Also known as sowbugs or pillbugs, woodbugs are harmless creatures that tend to live in moist areas in order to breathe through their gills. They eat decaying leaves and vegetables, or even new plants causing damage to gardens. When startled the woodbug will roll into a tight protected ball.


Earwigs – Despite having visible pinchers on the lower abdomen, the earwig cannot inflict damage to humans and are generally harmless. They congregate in wet, cool areas of the house or in the garden as they subside on a diet of live sprouts and decaying vegetation. An earwig infestation can be hard to manage as they only come out at night.


Firebrats & Silverfish – Skinny, with a metallic or greyish color, firebrats and silverfish can be found in wet or dark areas and are an unsightly nuisance. Firebrats generally prefer the heat and silverfish prefer the cold. The average insect can live up to six years, so these infestations can endure for a long time if not addressed directly.


Boxelder Bugs – Seeking refuge once the weather starts to cool, these beetles will begin to gather on the outside walls of homes. They will try to make their way inside over the winter and emerge in the spring months. They are not harmful and do not cause structural damage, but they are a nuisance and can cause “spotting” on furniture from their droppings. Boxelder bugs are easy to spot from their distinct markings: black with red stripes.
