Questions people ask

Can I just leave the nest alone until winter?

If it's out of the way, often yes. Around Round Rock, nests die back with the first hard freeze, around November.

Should I be worried about a nest in the ground?

Yes, if it's near a path or play area. Ground nests are usually yellowjackets. Mowing over them sets them off.

Do wasp traps work?

They catch some yellowjackets, but rarely fix a nest problem. Place them away from where people sit.

What time of day should a wasp nest be treated?

At dusk or after dark, when they're home and calm.

Can I seal the hole wasps are using?

No. Sealing traps them inside. They may chew into your house. Treat first, then seal once activity stops.

How seriously do people take wasp problems?

Around Round Rock, most people act once a nest is near a door, deck or play area, where stings are most likely.

Are hornets common in Round Rock?

Bald-faced hornets are, in trees and on eaves. Most stings come from yellowjackets, though.
