The remote-controlled insecticide applicator is especially for destroying wasps' nests. The applicator consists of a handle which extends e.g. for 3 or 4 metres and has brackets on its end to hold the insecticide spray container. - The end of the handle is also equipped with a spring-loaded lever system with a knob which presses down on the spray container control button when pulled down by a wire connected to a handle.
