These yellow and black wasps are Toronto’s most aggressive. Yellowjackets build massive colonies with thousands of workers. Ground nests hide in old rodent burrows underground. Aerial nests appear in wall voids and eaves.

Yellow jacket wasp colonies become extremely defensive in fall. Workers scavenge for sugary foods around garbage cans. One nest can house up to 15,000 angry insects. Our techs wear full protective suits for removal.

Paper wasps create umbrella-shaped nests under roof overhangs. These social wasps are less aggressive than yellowjackets. They build small colonies with 20-75 workers maximum. Paper wasps actually help control garden pests naturally.

Their papery nests look like upside down umbrellas hanging. Queens start new colonies each spring in Toronto. Paper wasps rarely sting unless directly threatened. We remove them carefully to avoid unnecessary harm.

These large black and white wasps build football-sized nests. Bald-faced hornets are actually yellowjacket relatives, not hornets. They construct gray paper nests high in trees. Colonies can reach 400-700 aggressive workers by summer.

Their stings pack serious punch and hurt badly. Wasps of this type spray venom at threats. Workers guard nests within 10 foot perimeters aggressively. Professional removal prevents dangerous encounters with these giants.

Solitary wasps that build mud tube nests. Mud daubers rarely sting humans despite scary appearance. They hunt spiders to stock their larvae. These wasps work alone, not in colonies.

Female daubers collect mud to build small nests. They stuff paralyzed spiders inside for babies. Wasps like these actually benefit homeowners significantly. We relocate them when removal becomes necessary.

Sweet smells attract wasps like teenagers to pizza. Keep garbage cans tightly sealed and clean regularly. Fallen fruit under trees becomes wasp candy pick it up. Pet food left outside creates an all you can eat wasp buffet.

Sugary drinks and sticky surfaces need immediate attention. Wipe down outdoor tables after every meal or barbecue. Even that morning coffee spill can signal free food to scouts. Clean grills thoroughly because grease residue attracts hungry insects.

Wasps squeeze through gaps smaller than your pinky finger. Check roof eaves, siding corners, and window frames regularly. Caulk cracks around pipes, vents, and electrical fixtures immediately. Screen vents and chimney openings with fine mesh barriers.

Gaps under deck boards create hidden potential nesting sites. Fill these spaces with expanding foam or mesh screening. Door and window seals wear out over time replace them. Even tiny holes in soffits need quick attention.

Walk your property weekly during spring and early summer. Look for early nesting activity in sheltered corners. Small starter nests are easier to remove safely. Check under decks, in sheds, and around outdoor furniture.

Potential nesting sites include mailbox posts and playground equipment. Inspect tree branches overhanging your roof line regularly. Garden sheds and tool storage areas need monthly checks. Early detection saves you from major infestations later.

Trim tree branches away from your house exterior. Overgrown shrubs create protected potential nesting sites near foundations. Keep grass short and remove brush piles promptly. Dense vegetation provides perfect wasp hideouts.

Plant wasp repelling herbs like mint and spearmint strategically. Remove old stumps and dead wood from yards. Stack firewood away from house walls and foundations. Open lawn areas discourage nesting because wasps prefer shelter.
