Sticky traps

Note the greater catch on the lower traps demonstrating most flying invertebrates are flying close to the ground.Sticky traps are commercial traps used to trap pest species in greenhouses. They consist of a plastic sheet covered by a sticky substance. Most sticky traps are either yellow or blue, the colours attract different insect species and are chosen by the farmer in order to catch a particular pest species.
