Questions people ask
Can I seal the hole wasps are using?
They may chew into your house. Treat first, then seal once activity stops. No. Sealing traps them inside.
Will wasps come back to the same nest next year?
They don't reuse old nests. New queens often pick the same sheltered spots, though.
How long does wasp nest removal take?
Usually under an hour. Hidden nests may need a second visit a few days later.
What time of day should a wasp nest be treated?
At dusk or after dark, when they're home and calm.
Wasp or bee: does it matter?
Bees are fuzzy and rounder. It matters because honey bees can often be relocated. Wasps are smooth and narrow-waisted.
Do wasp traps actually work?
They catch some foragers but rarely solve a nest problem. Find and treat the nest itself.
Is cost the main reason people leave wasp nests alone?
More often the nest goes unnoticed or is hard to reach. A small, early nest is often cheap to remove. Not usually.
