Pest control in Fergus
Fergus pest control for older streets, growing subdivisions and rural edges, with a free quote in under 30 minutes.

In Fergus, the main pest call comes with the first cold nights. The town has the Grand River running through it and farmland around its edges, so mice and rats have shelter close by and look for warmer places to winter.
Why fall rodents are the main call in Fergus
Mice and rats do not need much room. A gap about the size of a quarter is enough for a rat, according to the Township of Centre Wellington, and mice fit through even less. Once inside, they nest in attics, wall cavities and garages.
Signs to watch for:
- Droppings along walls or in cupboards
- Gnaw marks on boxes, wires or wood
- Scratching or rustling at night
- Greasy smears along edges where they run
If you are not sure which animal you have, read our guide to mice vs rats. Our pages on mice and rats show the differences. Then see our rodent control service.
Homes in Fergus and what each tends to see
- Older streets near the downtown. Older foundations and cellars give mice easy ways in.
- Growth areas on the edge of town. The Township lists development applications for land along Beatty Line North, and newer homes there often back onto open ground. Fresh builds can have small gaps at service entries and garage doors.
- Rural edges and farm properties. Barns, sheds and stored feed bring rodents close to the house.
Seal-up checklist before cold nights
The Township’s own advice is a good start:
- Seal holes and cracks in foundations, walls and around doors and windows
- Fit metal door sweeps
- Keep firewood and lumber raised off the ground and away from the walls
- Use tightly sealed bins for garbage, and secure compost
- Do not leave pet food outside
These steps cut down the food, water and shelter pests look for. They will not remove mice that are already inside.
Rules and who to call
The Township of Centre Wellington says everyone has a role in rodent and pest prevention, owner or renter. If you rent, tell your landlord in writing. Wellington-Dufferin-Guelph Public Health says that for rodents, you can contact the local bylaw or property standards office if nothing is done.
Businesses in Fergus

Common questions
Why do mice come in each fall?
Mice follow shelter and food. When nights cool, fields and gardens offer less of both, so mice look for warm gaps in houses, garages and sheds. Sealing entry points before cold weather is the best defence.
