Claire's Jet Force Wasp and Hornet Killer with instant Freezing Action will shoot a 20-foot stream to actively provide rapid contact kill and rapid knockdown of wasps, yellow jackets and hornets. This product can be used both indoors (attics, basements, warehouses, and other places nest are built) and outdoors, on wasp and hornet nests. Take out the most infested wasp or hornet colonies with only one application. Best results can be obtained if nest is spayed in the evening when insects have returned. When using indoors, allow spray to dissipate before occupying treated area. Remove children, pets, birds, and cover fish aquariums before spraying.
