Wasps, hornets, and yellow jackets build nests in hard‑to‑see places—eaves, attics, wall voids, trees, and even underground. Catching a nest early makes removal safer and less expensive. Here are the most common signs of a wasp nest around your property.
1. Increased Wasp Activity: If you notice wasps or hornets flying back and forth to a specific area repeatedly—especially in a steady stream—there is likely a nest nearby. Watch from a safe distance to see where they enter and exit.
2. Visible Nest Structures: Paper wasps build open, umbrella‑shaped nests under eaves and in corners. Hornets and yellow jackets build enclosed, papery nests that can be football‑shaped or located inside wall voids. You may see the nest itself or notice insects disappearing into a hole in the wall or ground.
3. Buzzing or Humming Noises: In walls or ceilings, a persistent buzzing sound—especially during the day—can indicate an active nest inside the structure. This is a serious situation that requires professional help.
4. Chewed Wood or Paper: Wasps chew wood fibers to build their papery nests. You may see small scraped patches on fences, decks, or wooden furniture.
5. Aggressive Behavior: If wasps become aggressive when you approach a particular area, they are defending a nest. Never approach or provoke them.
If you spot any of these signs, do not attempt to remove the nest yourself. For the cost of professional removal, see our wasp nest removal cost guide.
