ABSTRACT:
An animal operated insecticide spray delivery system operably enclosed in a barrel housing having an access opening to a feed source inside the barrel. The barrel is suspended in space such that the animal must thrust the head into the access opening to operate the spray delivery system. Should an animal butt the barrel, it will simply swing out of the way and in doing that it will lift which is not the habit of an animal to lift its head.
