Hornets
Hornets build aerial nests and aggressively defend colonies when threatened.
Background & Behavior
(Vespa spp.)
Hornets are large, social wasps known for their powerful sting and aggressive defense of their nests. They build paper-like nests in trees, eaves, and wall voids. Stings can cause severe pain and allergic reactions. Removing nests should be handled carefully or by professionals.
DIY Approaches
- Keep trash bins sealed and cleaned to avoid attracting foragers.
- Remove fallen fruit from yards promptly during late summer.
- Hang decoy nests early in the season to deter new colonies.
- Seal soffit gaps and vents to prevent enclosed nesting.
- Observe nests from a safe distance rather than attempting risky removal.
Professional Services
- Contact licensed stinging insect specialists for safe nest removal.
- Request aerial lift equipment for nests located high in trees.
- Have professionals treat adjacent voids to prevent recolonization.
- Coordinate emergency response services for nests near public entrances.
- Schedule preventative inspections each spring on large properties.
