Seal the chimney and use smoke or traps to remove wasps safely.
Wasps in a chimney can be removed by sealing the flue, using smoke to drive them out, or setting traps near the opening. Avoid using water or fire, as these can damage the chimney or provoke the wasps. For large nests, professional removal is safest.
Common methods to remove wasps from a chimney
- Seal the flue temporarily to prevent wasps from entering living spaces.
- Use smoke (safely) to encourage wasps to leave the chimney.
- Set wasp traps near the chimney opening to reduce the population.
- Apply insecticidal dust designed for wasps at night when they are less active.
