For Carpenter Bees: Treat active tunnels where carpenter bee activity has been observed. Leave the entrance hole open for 48 hours after application to allow the bees to contact and distribute the insecticide throughout the nest galleries. Then plug the entrance hole with a piece of wooden dowel coated with carpenter's glue or wood putty. Plugging the hole will prevent re-infestation of old nesting tunnels and reduce the chances of wood decay.
For Ground-Nesting Yellow Jackets: Using attached extension tube, spray product directly into holes in ground where yellow jacket activity has been observed. After 24 hours, cover the hole with soil. For best results, spray early in the morning or late in the evening when yellow jacket activity is low and most yellow jackets are in the nest.
