What happens to pesticides applied indoors?
Pesticides applied to soil, water, vegetation, or other surfaces indoors usually breakdown at a slower rate than pesticides applied outdoors. This is due primarily to the lack of sunlight indoors. This includes glass greenhouses, as the UV light necessary for pesticide breakdown is filtered out by glass. Pesticides applied indoors are not affected by wind or rain, and are less likely to move by mass transfer from the point of application. Vapor loss may also be less, as surfaces are not exposed to the heat of the sun.
