Pantry Moth Trap
The Pantry Moth, otherwise known as the Indian meal moth [ Plodia interpunctella ], is a pest of stored food products. The larvae of the moth feeds on cereals, flour, bread, snacks and other dried stored foods. The first indication of the pest can be the presence of silken webs in the food. These webs are used to form cocoons from which the moth pupae are formed. The adult moths do not cause any damage, it is the larvae that feed on the food stuff. Once they are present , foods become inedible and need disposing of.
The Pantry moth larvae are white-yellow with a brown head. They can crawl through small openings in packaging and through some cardboard containers. Once the larvae have developed fully they form a cocoon to pupate. Adult moths emerge from the pupae about 20 days later. Female moths can lay up to 400 eggs , these eggs hatch in about 7 days in warm conditions. The larvae then start to search for food stuffs to feed on. Pantry Moths can produce up to 8 generations a year.
To prevent Pantry Moth activity, clean food storage areas on a regular basis and place food in pastic sealable containers. Pantry Moth traps can also be used to monitor and control adult male moth populations. By catching the males , this reduces mating and therefore egg laying by the female moths.
The Pantry Moth trap uses a pheromone sex lure to attract male Pantry moths into the trap. The moths are then stuck on the sticky inside of the trap. The traps should be placed in food storage areas. The pheromone lure is active for up to six weeks, after this it should be replaced.
