Fumigation is commonly used to control stored product pests in food and grain, this involves the treatment of product with gasses which are able to diffuse throughout the treated area. The gasses used in fumigation (most often phosphine) are highly toxic to both insects and mammals (including humans) but when applied properly, no fumigant will remain in product after treatment is complete. Because of the high toxicity of fumigants, their use is restricted to qualified applicators and areas which can be tightly sealed.
Fumigation is employed to manage pests in stored food and grain products; this method includes treating the items with gases that permeate the treated area. The gases utilized for fumigation (mainly phosphine) are extremely toxic to both insects and mammals, including humans, but when applied properly, no residual fumigant remains after treatment is complete. Due to their high toxicity, fumigants can only be used by qualified applicators in sealed areas.
