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 frequently utilized to manage stored product pests in food and grain, which entails treating the products with gases that can permeate the treated area. The gases employed in fumigation (typically phosphine) are extremely toxic to both insects and mammals (including humans), but when applied correctly, no residual fumigant will remain in the product after treatment is complete. Due to the high toxicity of fumigants, their usage is limited to certified applicators and areas that can be tightly sealed.
