Grimsby neighbourhoods we serve
We cover Grimsby and nearby streets, including:
Common pests in Grimsby homes
Grimsby sits between Lake Ontario and the Niagara Escarpment — lakeshore cottages, mountain subdivisions and a growing town core. Escarpment moisture and mature trees favour carpenter ants; lake homes see spiders and mice.
Mice
Mice enter older lakeshore foundations and newer mountain-build garages each fall. See rodent control.
Ants and carpenter ants
Carpenter ants are common on the mountain and treed streets; pavement ants trail from patio stones in spring. See ant extermination.
Wasps and hornets
Eave and ground nests peak late summer across Grimsby Beach and the mountain lots. See wasp and hornet control.
Bed bugs
Travel and multi-unit housing introduce bed bugs. Aprehend only — no heat. See bed bug extermination.
Cockroaches
Mostly multi-unit and food-service kitchens along Main Street and plaza strips. See cockroach extermination.
Spiders
Lakeshore porches and cool basements collect spiders by August. See spider extermination.
When to call an exterminator instead of trying DIY
Store-bought traps and sprays can handle 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 baits, or you see large black ants indoors in late winter or early spring (possible carpenter ants).
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 Grimsby pest control visit
Free phone estimate
Call (905) 902-4222 and describe what you are seeing. We will tell you what it is likely to be, what treatment involves and the typical price range.
Inspection
Your technician confirms the pest, finds where it is living and checks how it got in. An inspection is required for an exact quote on larger jobs such as bed bugs or multi-unit 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 against the house, a leaking downspout or open garbage.

How to keep pests out of a Grimsby 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 they come inside.
Knock down small wasp nests in spring before they grow, if it is safe to do so.
Pest control in Grimsby: FAQ
Do you serve all of Grimsby?
Yes. We serve Grimsby neighbourhoods listed above and the surrounding streets. We also cover nearby towns linked on this page. Call (905) 902-4222 if you want to check your address.
How quickly can you come out in Grimsby?
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, 8:30 a.m. to 5 p.m. and we will give you the earliest appointment we have and tell you what to do in the meantime.
How much does pest control cost in Grimsby?
Mice packages are $279 for a one-time visit, or $549 with a one-year warranty. Rats are $279 for one visit, or $429 for two visits (+HST). For wasps, ants, spiders, fleas, cockroaches and bed bugs, ask for the typical range — confirmed on the free phone estimate. Your technician confirms the price before any work starts.
How do you treat bed bugs in Grimsby?
We treat bed bugs with Aprehend only. We do not offer heat treatment. Aprehend is a fungal product applied as bands where bed bugs travel; they pick it up and spread it in the harbourage. Prep instructions come with your booking.
Do you serve both lakeshore and mountain Grimsby?
Yes. We cover Grimsby Beach, downtown, the mountain neighbourhoods and addresses toward Casablanca and Nelles. Call (905) 902-4222 to confirm your street.
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.
What are your hours?
The office is open Monday to Friday, 8:30 a.m. to 5 p.m. Leave a message after hours and we will call you back the next business day. We do not offer 24/7 or emergency service.
