To kill a yellow jacket nest effectively and safely, follow these steps:
- Locate the Nest: Observe during the day to find the yellow jacket nest by watching where workers enter and exit. Mark the entry points.
- Treat at Night: Approach the nest at night when yellow jackets are less active and more likely to be inside the nest, reducing the risk of stings.
- Use Insecticide Spray: Apply a pyrethrum aerosol spray (e.g., Stryker 54 Contact Aerosol, PT 565) directly into the nest entrance to kill yellow jackets instantly.
- Apply Insecticidal Dust: After spraying, wait 10-15 minutes for the aerosol to dry, then dust the nest entrance and surrounding area with insecticide dust like Tempo Dust or D-Fense Dust to prevent new hatch-outs.
- Repeat if Needed: Check the nest the next day for activity. If yellow jackets are still active, repeat the treatment.
Additional Tips:
- Wear protective clothing when treating the nest.
- Dust insecticides like carbaryl or permethrin can be used for ground nests.
- Diatomaceous earth is a natural alternative but works slower.
- Use bug smoke bombs for hard-to-reach or underground nests, following safety precautions.
Treating the nest after dark is crucial for safety and effectiveness.
