Yellow Jacket Removal in Arnold & Jefferson County
Yellow jackets are the ones that ruin cookouts. They nest in the ground, in walls and in attics, and a nest can hold a few thousand by late summer.
They defend the nest hard. Mowing over one is how most people find out it's there. We locate the nest entrance and treat it so the whole colony is gone, not just the ones you see.
Signs you have yellow jackets
- Black and yellow wasps going in and out of a hole in the lawn or mulch
- A steady stream of them at a gap in siding or a vent
- Getting chased when you mow or weed-eat a certain spot
- Yellow jackets showing up inside near light fixtures (nest in the wall or attic)
How we handle it
- 1 Watch flight paths to find the actual nest entrance.
- 2 Treat directly into the nest with a dust or foam that the colony spreads.
- 3 Come back if there's still traffic after a few days.
- 4 For wall nests, never seal the hole first. They'll chew through drywall into the house.
What you can do in the meantime
- Fill old rodent holes and low spots in the yard in spring
- Keep lids on trash and pick up fallen fruit
- Cover drinks outside in late summer
When to call us
If you know where a yellow jacket nest is, call. Pouring gas or water in the hole doesn't work and gets people stung.
