1. Pheromones for Insects that Eat Your Food - There are several insects that eat the food you store in your pantry. One insect is found more often than any other on stored food and grain in the United States is the Indianmeal moth.
INDIANMEAL MOTH (Plodia interpunctella)
These moths are often called "miller moths" or pantry moths and can be seen flying around the house. This is one of the easiest stored food insects to identify because the adults have a colorful appearance and the larvae (which look like yellowish-white worms) leave a silken webbing trail wherever they crawl. Newly emerged adults have bi-colored (copper and tan) wings and measure about 1/2" from top to bottom. The IMM larvae most commonly feed on grain products including flour, cereal, nuts, bird seed and pet food.
Trap placement and use: Although there is no exact number of traps that you should place within your home, we can give you some general guidelines. In general, a home should use one trap in a small room such as a pantry. Depending upon the size of your kitchen, you should use one or two traps to capture moths in that room. If you have rooms where you store pet food or bird seed you should place one trap in those areas. Traps should be placed at eye level for easy access. Traps are effective for two months, after this they should be replaced with new ones. For more information click here.
RED AND CONFUSED FLOUR BEETLES (Tribolium spp.)
The "Red Flour Beetle" and the "Confused Flour Beetle" are actually 2 species that are very similar in appearance and diet . These beetles are small at 4 - 5 mm or 1/6 to 1/5 of an inch in length and are reddish bown in color. Often found in flour, they may infest any product made with grain, but they cannot infest sound (undamaged) grain. Flour beetles require about a month to complete their life cycle. Adults may live up to three years.
Trap placement and use: Since flour beetles usually won't fly into a trap, It is best to trap them with flat traps or pitfall traps. Flour beetles typically only travel a few feet from their food source, so traps placed directly in the food pantry will give you the best indication if these beetle pests are present or if you have eliminated the problem.
2. Pheromones for Insects that Eat Your Clothes- If you have ever had holes eaten in your sweaters or suits, you have most likely dealt with the Webbing Clothes moth.
WEBBING CLOTHES MOTH (Tineola bisselliella)
With the decreased use of pesticides on textiles, the incidence of clothing and rugs damaged by the Webbing Clothes moth has increased significantly in recent years. Fabrics injured by clothes moths have holes eaten through them by small, white larvae. Materials left undisturbed for some time or stored in dark places (such as a closet, attic, or drawer) are most severely injured by these insects. The adults are small (7 - 10 mm or 1/4 - 3/8 inch in length) and champagne-colored. They can often be seen running over the surface of the infested goods when exposed to light or flying somewhat aimlessly about the house or in closets. Clothing moth larvae (worms) feed on wool, hair, feathers, furs, upholstered furniture, occasionally on dead insects, dry dead animals, animal and fish meals, milk powders such as casein, and nearly all animal products such as boar bristles, dried hair and leather. Adults moths do not feed on anything. For more information click here.
Trap use and placement: These traps should be used in areas where moths are likely to be found (see above). One trap per closet or room is sufficient. Traps should be placed on the floor or on a shelf. Lures should be replaced every two months. Traps should be replaced when full of insects.
Second only to Webbing Clothes moths, the Casemaking clothes moth causes extensive damage to many different materials. Potential foods could be any feather material, woolens, rugs, felts, hair and furs (This includes animal mounts and fur garments). It is reported that it will also feed on spices, tobacco, hemp and skins. For more information click here.
