Insect Fogger We believe fogging to be an extremely effective method of pest control. That’s why we have developed the FOG RxTM line of thermal foggers. When used in conjunction with Bonide Mosquito Beater or Bug Beater Fogs, our FOG RxTM machines produce dense fog that permeate foliage, cracks, crevices and other hiding places, quickly collapsing insect populations, leaving a safe, pest free environment for people, pets, plants and livestock—without pesticide residue.
