Where They Come From

Where Wasps & Hornets Come From

Seasonal Behaviour

In spring, queens start new colonies. By late summer, nests are largest and insects are most defensive.

Nest Sites

Eaves and soffits, attic or wall voids, deck undersides, sheds, trees and shrubs, fence posts, and ground cavities (for yellowjackets).

Common Types

Paper wasps build open, umbrella-shaped nests. Yellowjackets and bald-faced hornets (a type of wasp) make enclosed paper nests and are more aggressive around food.

Prevention

What You Can Do at Home

  • Keep outdoor food and drinks covered; clean up BBQ spills and pet dishes.
  • Repair screens; seal gaps at soffits, fascia, and around utility penetrations.
  • Trim vegetation touching structures; store lumber and ladders away from walls.
  • Tightly close garbage and compost; rinse recyclables, especially sweet containers.
  • Avoid blocking nest entrances or swatting near a nest — this triggers defensive behaviour.
  • Do not use indoor bug bombs for wall-void nests; pressure can drive insects into living areas.

Root Causes

What Attracts Them to Homes

  • Food & scents: Sweet beverages, fruit, meat and BBQ, open garbage, fallen apples.
  • Shelter: Protected cavities such as eaves, attics, wall voids, and mailbox posts.
  • Water: Leaky hoses, birdbaths, and dripping taps in hot weather.

Why It Matters

Why Wasps & Hornets Are a Concern

Sting Risk

Defensive behaviour near nests can lead to multiple stings; some people may have severe reactions.

Activity Escalation

Colonies peak in late summer and fall; ground nests and wall-void nests are hard to treat safely.

Access Issues

Nests inside structures require proper products and methods to prevent insects from entering the home.

FAQ

Frequently Asked Questions

What's the difference between a wasp and a hornet?

"Hornet" commonly refers to bald-faced hornets here — technically a type of wasp. Paper wasps are less aggressive; yellowjackets and bald-faced hornets defend nests vigorously.

Can I remove a nest myself?

Small, exposed paper-wasp nests early in the season may be DIY. Larger nests, ground nests, and any nest in a wall or attic are best handled professionally for safety and effectiveness.

Will wasps reuse the same nest next year?

No — the paper nest isn't reused. However, new queens may overwinter nearby and choose the same area, so sealing entry points matters.

How do you treat a nest inside a wall?

We treat the colony at the source using targeted products, then advise on sealing and repair to prevent re-entry. Avoid plugging holes before treatment.

How long does removal take?

Most exposed nests can be treated on our first visit. Wall-void and high-access nests may require specialized equipment and a scheduled time window (often evening or early morning when activity is low).

Is treatment safe for my yard and pets?

Yes — when applied as labelled. We'll provide re-entry times and simple post-treatment steps.

Ready for Fast, Reliable Help?

Wasps and hornets are common in Ontario — but they don't have to take over your yard or home. If you've spotted a nest or increasing activity, the first step is understanding the issue. The next step is knowing when it's time for professional help.
