Wasp Nest Removal in St. Catharines

Wasps & Hornets in St. Catharines: what to know

St. Catharines is Niagara's largest city, with everything from older brick homes near downtown and Port Dalhousie to newer subdivisions in the west end, plus plenty of apartments and student rentals near Brock University.

• Patios, decks and outdoor eating spots near the water attract wasps in late summer.
• Mature trees and older outbuildings in neighbourhoods near the canal give wasps plenty of places to build nests.
• Rentals with older porches and sheds often have wasp nests nobody notices until late summer.
• Gaps in older siding, soffits and rooflines are common spots for wasps to build nests inside walls.

Wasp nests are usually biggest, and wasps most aggressive, in late summer and early fall.

Signs of wasps & hornets in your home

• Wasps flying in and out of a gap in siding, soffits or the roofline
• Grey papery nests under eaves, decks, in sheds or in shrubs
• Wasps coming from a hole in the ground in the lawn or garden
• A lot of wasp activity around garbage, recycling or outdoor eating areas

What wasp nest removal usually involves

A provider locates the nest, confirms the species, and treats it, usually at a time of day when wasps are less active. Nests in wall voids or the ground often need a specific approach. They can also advise on sealing spots so wasps don't rebuild there.

Prevention tips for St. Catharines homes

• Keep garbage and recycling bins closed and cleaned
• Cover food and drinks outdoors in late summer
• Seal gaps in siding, soffits and vents in spring before queens start nests
• Check sheds, playsets and decks for small starter nests early in the season

When to call

Call when a nest is near doors, play areas or high traffic, inside a wall, or if anyone in the home is allergic to stings. Don't try to knock down or seal a nest yourself.
