Quick answer
What to know first
Paper wasp nests are often open, umbrella-shaped combs under eaves or sheltered structures. Yellow jacket nests are often hidden in ground holes, wall voids, or enclosed spaces with heavy traffic at one entrance.
Start here
- Whether the nest is open and visible or hidden in a cavity
- Traffic level at the entrance and proximity to people or pets
- Ground holes, wall gaps, soffits, eaves, decks, and sheds

FAQ
Can I plug a yellow jacket hole?
No. Blocking the entrance can force insects indoors or create aggressive activity.
Are paper wasps always dangerous?
They are often less aggressive away from the nest, but nests near people still need caution.
