You might have a yellow jacket problem if you notice the following signs:

Sightings: If you frequently see yellow jacket wasps around your property, especially in larger numbers than usual, it could indicate a nest nearby.

Nesting Sites: Yellow jackets often build nests underground, in wall voids, or in other hidden areas. Look for signs of nests such as small holes in the ground, activity around eaves or rooflines, or buzzing around bushes or shrubs.

Increased Aggression: Yellow jackets can become more aggressive if they feel their nest is threatened. If you notice them behaving aggressively towards people or pets, it could mean their nest is nearby.

Damage to Plants or Structures: Yellow jackets may cause damage to plants or structures while foraging for food or building their nests. Look for signs of chewed leaves or wood, especially near potential nesting sites.

Unusual Sounds: If you hear buzzing sounds coming from inside walls, ceilings, or other structures, it could indicate a yellow jacket nest.

If you suspect you have a yellow jacket problem, it’s best to address it promptly to prevent it from getting worse.
