Wasp Nests Found in Scarborough Homes Need a Different Approach
Wasp nests in Scarborough don’t always appear where you can see them. A yellowjacket nest or baldfaced hornet nest grows inside wall voids, eaves, and chimney gaps all summer long. The active colony builds using chewed wood fiber and saliva, expanding weekly. By late summer, colony size reaches tens of thousands of individual workers inside your home’s structure.
Gaps in brickwork, broken window screens, and open vent openings give queens direct access into single family homes across Malvern and Agincourt. The queen overwinters in the old soffit nest or roof overhang nest, emerges mid spring, and rebuilds in the exact same spot. Without treating the pheromone trail, re-colonization risk stays active the following season. The anaphylactic risk from an untreated wasp infestation is life threatening under Ontario’s Pesticides Act R.R.O. 1990, Reg. 914, only a licensed applicator can treat stinging insect nests on suburban residential properties.
