Pest Control in Guelph, Ontario
Guelph's mix of century homes, student rentals and newer subdivisions each attract different pest issues. Harnet provides local, licensed pest control across the city with a focus on lasting results — not repeat call-outs.
Guelph combines historic century homes downtown, University of Guelph student rentals, and rapidly growing subdivisions in the south end and Westminster Woods. Each of those attracts different pests: mice and carpenter ants in older neighbourhoods, bed bugs and cockroaches in student rentals, and wasps and ants across every part of the city in summer.
Harnet Pest Control is a local Waterloo Region company that services Guelph regularly. Every Guelph visit is performed personally by a Licensed Ontario Pesticide Applicator, using Health Canada registered products applied according to label directions and an IPM approach that prioritizes long-term results.
