Abstract
This invention relates to a device for controlling certain common insect pests of stored food products in human residences, food storages and the like. It comprises, generally, a substrate, such as paper, cardboard or plastic and a deposit of silica aerogel particles releasably bonded to the substrate. The strength of the bond prevents the silica aerogel particles from being released by air currents but allows the particles to be picked up by some insects that contact the deposit.
