Paper wasps, yellow jackets, and mud daubers build nests in eaves, attics, and block walls each summer.
About wasps & hornets in the Central Valley
Stinging insects are a real safety concern in the Central Valley — especially yellow jackets, which are aggressive ground nesters, and paper wasps, which build umbrella-shaped nests in eaves and patio covers. People with allergies can have life-threatening reactions to a single sting, and a single yellow jacket nest can contain thousands of individuals by late summer.
Why it's a problem
Stings can cause severe allergic reactions. Yellow jackets in particular defend nests aggressively and can deliver multiple stings. Nests inside walls or attics also attract secondary pests when abandoned.
What homeowners can try first
Real tactics that can help with light pressure — and the honest limits of each.
- Knock down small, newly-started paper wasp nests early in the season with a long stick at dusk.Limit: Only safe for small, brand-new nests and only when you can clearly identify the species.
- Hang wasp decoy nests in early spring.Limit: May discourage paper wasps from a specific spot — doesn't help with established colonies.
- Keep trash cans sealed and clean up fallen fruit.Limit: Reduces food attraction but doesn't eliminate established nests.
- Avoid bright florals and sweet drinks at outdoor meals.Limit: Reduces casual encounters, not nest activity.

The professional process for wasps & hornets
Every pest has a different biology — and a different process. Here's how we handle wasps & hornets specifically.
- 01
Identification & risk assessment
We identify the species (treatment is very different for paper wasps vs. yellow jackets vs. mud daubers) and assess access risk.
- 02
Direct nest treatment in protective gear
Treatment is performed in proper PPE, typically at dusk when the colony is back in the nest.
- 03
Nest removal where safe
We remove accessible nests after treatment so they don't attract scavengers or get re-occupied.
- 04
Exclusion guidance
Eave gap sealing, attic-vent screening, and rodent-hole repair so next season's queens don't find easy nesting spots.
