Pantry Pests

Indian Meal Moths

Indian-meal moth larvae can infest a wide range of dry foodstuffs of vegetable origin, such as cerealbreadpastaricecouscousflourspicesdried fruits, and nuts. More unusual recorded foods include crushed red pepperchocolate and cocoa beanscoffee substitutecookies, dried mangelwurzel, and even the toxic seeds of jimsonweed(Datura stramonium). They have also been known to infest commercial pet food, such as cracked corn used for bird feed. They often leave webbing in the food they infest.

Red Flour Beetle

The red flour beetle attacks stored grain and other food products including flour, cereals, pasta, biscuits, beans, and nuts, causing loss and damage.

Grain Beetle

The grain beetle can be found throughout the world, and it loves to attack many common types of food. Macaroni, sugar, biscuit mixes, rice and cereal frequently fall victim to the grain beetle. Homeowners commonly find grain beetles in locations where dry food is stored. Although diseases aren't associated with grain beetles, nobody wants to eat cereal that has had grain beetles  in it. A grain beetle cannot eat through a hard seed of corn, but it loves attacking processed cereal.  The Saw Tooth Grain Beetles is a common, worldwide pest of grain and grain products as well as chocolatedrugs, and tobacco.

Carpet Beetle

Carpet beetles, as their name implies, sometimes infest carpets. Similar to clothes moths, the pests also feed on many other items composed of wool, fur, felt, silk, feathers, skins, and leather. Such materials contain keratin, a fibrous animal protein which the larvae are able to digest. Cotton and synthetic fabrics such as polyester and rayon are rarely attacked unless blended with wool, or heavily soiled with food stains or body oils. Infestations of carpet beetles can develop undetected, causing harm to vulnerable items.

Larder Beetle

The larder beetle is a commercial pest as well as a household pest. This is a cosmopolitan species which was historically a pest of cured meats in Europe, the United States, and Canada. The use of refrigeration, the purchase of meats in small quantities, and the lack of home curing of meats, have decreased the economic importance of this insect. However, these beetles are still common in homes, museums, mills, livestock facilities, and any place that contains a suitable food source. Typically, these would include any animal by-product such as dried dog food, furs, hides, and feathers. Also, many pantry items can become infested. Another potential food source are dead insects in attic and wall voids that become trapped when they seek an overwintering site. In the fall insects such as flies, bugs, beetles and wasps, accumulate in attics and similar spaces in the home. Many of the hibernating insects die, attracting larder beetles which lay eggs on dead insects. The larvae of the larder beetle then feed on the dead insects.
