Secure Indoor Spaces Close windows, doors, and screens to ensure wasps don’t enter indoor living spaces.How to Locate a Yellow Jacket Nest in a Safe Manner
- Locating the nest in a safe manner is very crucial for addressing the infestation:
-

Common Nesting Sites: Check underground holes, bushes, wall voids, attic spaces, and hollow logs to identify potential nest locations.
-
Mark the Location: Safely mark or note the nest site clearly without approaching too closely to avoid provoking the colony.
Risks Associated with Large Yellow Jacket Populations
- A significant number of yellow jackets near homes poses real risks, including:
-
Aggressive Defense Behavior: Yellow jackets can become aggressive if they sense their nest is threatened, attacking and stinging multiple times.
-
Allergic Reactions: Multiple stings increase the risk of severe allergic reactions, which may require immediate medical attention.
