Insect traps are used to monitor or directly reduce insect populations. They typically use food, visual lures, chemical attractants and pheromones as bait and are installed so that they do not injure other animals or humans or result in residues in foods or feeds. Visual lures use light, bright colors and shapes to attract pests. Chemical attractants or pheromones may attract only a specific sex. Insect traps are sometimes used in pest management programs instead of pesticides.
How it works
Sticky traps may be simple flat panels or enclosed structures, often baited, that ensnare insects with an adhesive substance. They are widely used in agricultural and indoor pest monitoring. Shelter traps, or artificial cover traps, take advantage of an insect's tendencies to seek shelter in loose bark, crevices. They are effective against stored product beetles and cockroaches.
Flying insect traps are designed to attract pests but not beneficial insects. Most use a liquid food lure and are of a bottle or bag design, so that once inside insects, such as wasps and flies cannot find their way out. Pheromone traps work well with moths, trapping the male moth and so interrupting the breeding cycle.
