Application Method

Apply insecticidal dust (deltamethrin, permethrin, or carbaryl) directly into ground-nesting wasp nest entrance. Use hand duster or bulb duster to puff dust into opening. Apply at dusk or after dark when wasps have returned to nest and are less active. Use 1-2 tablespoons of dust per nest. Dust adheres to wasps as they move through nest and is transferred throughout colony. After application, do not seal entrance immediately - allow wasps to continue moving through dust for maximum colony exposure. Seal entrance next day after wasp activity ceased. Dust provides quick knockdown and residual control.

Timing

Treat at dusk or after dark when wasps are in nest and less defensive. Avoid treating during heat of day.

Frequency

Single treatment usually sufficient. Retreat after 2-3 days if activity persists.

Preparation Required

Locate nest entrance during daylight hours. Mark location. Plan approach and escape route. Have protective gear and dusting equipment ready. Wait until dusk to treat.

Follow-up Required

Monitor nest from distance for 24-48 hours. Seal entrance with soil once activity ceased. Fill hole completely to prevent reuse. Monitor area for additional ground nests.

Safety Precautions

  • Wear protective clothing and face protection
  • Treat only at dusk or after dark
  • Have escape route planned
  • Do not shine flashlight directly at nest entrance - use indirect lighting
  • Keep children and pets away from area
  • Mark treated nests to avoid disturbance
