Common pests in Kitchener homes

Kitchener mixes century homes, post-war bungalows, new subdivisions and a fast-growing number of apartment and condo towers. Each one gets its own pest problems.

Mice and rats. Mice are the most common call we get from October to March. Older homes around downtown, Cherry Hill and Rockway have stone or block foundations with gaps around pipes and vents, and a mouse needs a hole about the size of a dime. Newer homes in Huron Park and Doon get mice through garage door seals, utility lines and weep holes. Rats show up near the Grand River, along rail lines and around restaurants and garbage storage. See rodent control.

Ants and carpenter ants. Pavement ants come up through basement slabs and patio stones in spring. Carpenter ants are the bigger worry in neighbourhoods with mature trees, such as Forest Hill, Stanley Park and Victoria Park, where they nest in damp wood around decks, windows and rooflines. See ant control.

Wasps and hornets. Yellowjackets nest in soffits, wall voids and the ground. Bald-faced hornets hang paper nests in trees and hedges. Both get more aggressive in late August and September, just as people spend more time outside. See wasp nest removal and hornet nest removal.

Bed bugs. Bed bugs travel with people, so they turn up in apartments, rooming houses, student rentals and single-family homes alike. They don’t mean a home is dirty. Region of Waterloo Public Health advises tenants and landlords to act quickly and work together, because bed bugs spread between units. See bed bug extermination.

Cockroaches. German cockroaches are almost always an indoor, multi-unit problem in Kitchener: kitchens and bathrooms in apartment buildings, restaurants and shared housing. See cockroach extermination.

Spiders, fleas and other insects. Spiders build up around porch lights and basements in late summer. Fleas come home with pets or with a move into a home where pets lived. Centipedes, earwigs and cluster flies round out the list. See spider control, flea extermination and fly control.

When to call an exterminator instead of trying DIY

Store-bought traps and sprays work for a single mouse or a small ant trail. Call a professional when:

You see mouse droppings in more than one room, or hear scratching in walls or ceilings at night.
Ants keep coming back after you’ve used baits, or you see large black ants indoors in late winter or early spring, which can mean carpenter ants nesting inside.
A wasp or hornet nest is inside a wall, under siding or high on the house.
You wake up with bites in rows or clusters, or find small blood spots on sheets.
You see cockroaches during the day, which usually means a large population.

What to expect from a Kitchener pest control visit

Free phone estimate. Call 519-957-1766 and describe what you’re seeing. We’ll tell you what it’s likely to be, what the treatment involves and the typical price range.
Inspection. Your technician confirms the pest, finds where it’s living and checks how it got in. An inspection is required for an exact quote on larger jobs such as bed bugs or commercial work.
Treatment. We treat the source: bait stations along rodent runways, gel bait in cockroach harbourages, Aprehend bands for bed bugs or a direct nest treatment for wasps and hornets.
Prevention. We seal the mouse entry points we find at ground level and show you what to change, such as firewood stacked against the house, a leaking downspout or an open garbage bin.

Pest control for Kitchener businesses and landlords

Kitchener’s restaurants, offices, shops and rental buildings need a contractor who works around them. We provide commercial pest control for restaurants and food businesses, offices, retail stores, property managers and multi-unit residential buildings. Visits are scheduled during business hours, Monday to Friday, and we’ll work with your staff, tenants and superintendent.

How to keep pests out of a Kitchener home

Seal gaps around pipes, cables and dryer vents, and fix worn door sweeps before October.
Keep firewood, mulch and leaf piles away from the foundation.
Store garbage, recycling and green bin waste in sealed containers.
Fix leaks and damp wood, which draw carpenter ants.
Check second-hand furniture and luggage for bed bugs before it comes inside.
Knock down small wasp nests in spring before they grow, if it’s safe to do so.

Pest control in Kitchener: FAQ

Do you serve all of Kitchener?

Yes. We serve every Kitchener neighbourhood, including downtown, Victoria Park, Cherry Hill, Forest Heights, Doon, Pioneer Park, Huron Park, Williamsburg, Country Hills, Stanley Park, Chicopee, Grand River North and Bridgeport. We also cover Waterloo, Cambridge and Guelph. Call 519-957-1766 if you want to check your address.

How quickly can you come out in Kitchener?

It depends on the season and the schedule that week. Wasp season and the first cold snap in fall are our busiest times. Call us Monday to Friday between 8:30 a.m. and 5 p.m. and we’ll give you the earliest appointment we have and tell you what to do in the meantime.

How much does pest control cost in Kitchener?

Typical ranges before HST are from about $200 for a wasp nest, about $300 to $430 for ants, about $280 to $550 for mice, about $500 for fleas, from about $800 for cockroaches and about $1,000 to $1,400 or more for bed bugs. Your technician confirms the price before any work starts.

Why do I get mice every fall in Kitchener?

Mice move indoors when nights drop toward freezing, usually in October. Older Kitchener homes have stone or block foundations with gaps, and newer homes have utility lines and garage seals that mice squeeze through. Sealing the ground-level gaps and placing bait stations along their runways is what stops the cycle.

Do you treat apartments and rental properties in Kitchener?

Yes. We treat single units and whole buildings for landlords, property managers and tenants. Bed bugs and cockroaches spread between units, so the best results come when neighbouring units are inspected too. For multi-unit buildings, an inspection is required for an exact quote, and we can schedule around tenants.

Are your treatments safe for kids and pets?

Yes, when the instructions are followed. We use Health Canada-registered products and apply them where pests live, in cracks, voids, locked bait stations and around the outside of the house. Your technician tells you how to prepare, which areas to avoid and for how long, and what to do with pets and fish tanks.
