Control Yellowjackets With Synthetic Insecticides
Control with a Pyrethroid Insecticide
Many insecticides to control yellowjackets are aerosol products containing pyrethrin or pyrethrum. They emit a stream of insecticide 6 to 8 feet long, allowing you to spray an aboveground nest from a safe distance.
One spritz is likely to kill the colony and not harm any other insects in your landscape. Read the label for application directions and other advice for safe use of the product. As soon as the wasps are dead, remove the exposed nest to keep birds from eating any poisoned larvae left inside.
Spray the long stream of insecticide into entrances of underground nests in the evening when most of yellowjackets are within. Then plug the entrance hole with steel wool or cotton. Spray the plug material as well as the soil around the entrance to kill any stragglers that come on the scene.
Go to Yardener's Tool Shed for information about Wasp and Hornet Killer which includes yellowjackets.
