Do not attempt to destroy a wasp nest during the daylight hours. Night time or twilight on cool days is the best time to deal with the nest. Do not hold torches near to you as disturbed wasps may fly at the light. Leave the bottle in the entrance to prevent any wasps from emerging. Do not light the fuel.
Nests located in banks, walls, tree trunks or buildings require the use of insecticides.
Before placing the fumigant in the nest, precut a sod of earth to the appropriate size of the nest entrance. Place 1-3 pellets of fumigant in the nest along with a damp piece of paper in dry weather. Place the sod of earth over the entrance with the grass side down being careful not to cover the fumigant with earth. Destroying A Paper Wasp Nest To kill the wasps in the nest simply spray with household flyspray. Manoeuvre a plastic or paper bag over the nest and clip it off at the stem before sealing the bag and disposing of it in the rubbish.
