In many cases, the product of choice for fogging applications in the food industry is Vapona (DDVP). Vapona is an organophosphate insecticide registered by EPA for the control of many stored-product pests. These infest food manufacturing, processing and storage facilities. The high vapor pressure of Vapona helps it to move into cracks and crevices, under equipment and penetrate debris. Professionals often recommend Vapona over other fogging agents because of its superior efficacy, dispersion and penetration capability.

Pyrethrin, a botanical insecticide extracted from certain chrysanthemum flowers, is probably the most commonly used fogging insecticide. It is noteworthy for its mammalian safety and fast insect knockdown characteristics. Some insects can rapidly metabolize pyrethrin they have contacted and recover. Therefore, it is important for proper duration of exposure. Most pyrethrin products include additional ingredients called synergists to help prevent insect recovery. However, the synergists disqualify most pyrethrin products from organic classification.
