Limestone, Rivers and Students: Guelph's Pest Mix
Guelph's beautiful limestone century homes — downtown, the Ward, Exhibition Park — come with limestone-era foundations: winter mouse territory, block after block. The Speed and Eramosa rivers junction in the middle of the city, running rodents and wildlife through every central neighbourhood.
The University of Guelph shapes the south end: one of Ontario's densest student-rental markets, with the twice-yearly turnover that moves bed bugs and cockroaches between units. And the growing south-end subdivisions add construction-displacement mice with every new phase toward Clair Road.
Every technician is employed, licensed under the Ontario Pesticides Act, and background-checked.
What Guelph Calls Us For
Mice in the limestone wards every winter — exclusion-first, because century foundations open new gaps each season. Bed bugs and cockroaches in the student south, discreet and documented. Carpenter ants under the old canopy. Wasps and hornets all summer at $247 per nest. Squirrels and raccoons along the river corridors into attics.
Every job carries our guarantee — pests return within the window, so do we.

Year-Round Protection for Guelph Homes
Pests in Guelph run on a calendar — ants and wasps in summer, mice and rats when the nights cool, spiders and cluster flies in fall. A one-time treatment solves today's problem; a protection plan makes sure the next season's problem never starts. If pests return between visits, so do we — at no charge.
4 seasonal visits — ants, wasps & general insects handled before they peak.
Quarterly rodent defence — inspection, exclusion & treatment every season.
Insects + mice together — the plan most Guelph homeowners choose.
6 visits, insects + mice, free mosquito & tick treatment included.
12 monthly visits — everything covered, including wildlife & mosquito.
One honest annual price. No monthly billing, no initiation fee, no contract traps — unlike the big-brand plans that quietly add up to more than double by year's end.

Frequently Asked Questions
How much does pest control cost in Guelph?
Wasp and hornet nest removal is $247 per nest. One-time mice or ant treatment starts at $345, Complete Mice Protection is $495, and general insect control runs from $395 exterior or $475 interior and exterior. Year-round plans start at $845/yr.

Why do Guelph's limestone homes get mice every winter?
Limestone-era foundations settle and open hairline gaps every season — invisible from inside, obvious to a mouse. Exclusion-first treatment ends the annual cycle that bait alone never does.
I'm in a student rental near U of G — can you help quietly?
Yes. Bed bug and cockroach treatments are discreet, guaranteed, and documented for landlords when needed. Turnover weeks are the ideal treatment window.
Do you handle wildlife along the Speed River?
Yes — the river corridors run squirrels and raccoons to rooflines across central Guelph. Humane removal, sealed entries, screened vents.
Do you serve Rockwood, Fergus and Elora?
Yes — Wellington County is on the same routes. Call (705) 302-1887 for a window.
