| American spider beetle is generally of minor importance. It feeds on both animal and vegetable products, including melon seeds, mixed feed, grain, tobacco, cayenne pepper and woolen carpeting. It is most commonly seen in homes but has also been found in warehouses and flour mills. These beetles are also known to breed in large accumulations of pet, bird, bat and rodent feces often found in bird or bat roosts. |

| Bean weevils infest only whole beans and other legumes and do not infest other types of stored foods such as cereals or whole grains. The control of any stored product pest involves many steps, primary of which is discovery of infested food items or other sources of infestation (e.g., food spillage accumulation). When bean weevils are present, all items containing or made of whole beans need to be examined. |

 |
| Cigarette beetle is a pest of dried tobacco in tobacco warehouses and processing facilities. Interestingly, this beetle is not commonly found infesting stored cigarettes or cigars in stores or homes. It will infest a wide variety of food products and is common in pet food, cereals, nuts, dried peppers, spices, raisins, seeds and dried straw flours. Cigarette beetle larvae have also been found to feed on the stuffing inside upholstered furniture. The cigarette beetle is also a major pest in museums, where it attacks botany displays and other artifacts of vegetative origin. |

 |
| Dried fruit beetle is found worldwide, especially in regions where fruits are grown, processed and stored. It is a prominent pest in California. This beetle attacks both fresh, ripened fruit and dried fruits prior to storage and packaging. This beetle is especially fond of figs and dates and is a common pest of raisins. |

 |
| Drugstore beetle's Latin name of paniceum was derived from its habit of feeding on bread. Its common name was given because it can be found infesting drugs and similar products. This beetle, however, will literally feed on any dried, food-based material, especially dried pet foods, cereal products and spices. It has also been observed to damage books by feeding on the bindings. The drugstore beetle can be found worldwide, but is more common in regions with warmer climates or in heated structures in temperate climates. |

 |
| Foreign grain beetles are fungus feeders and are even capable of surviving on pure mold cultures. As a food pest, it is not a great economic concern because it only attacks grain products that are moist, moldy and out-of-condition. Food products attacked include cereal grains, flours, beans, dates, figs, biscuits, yams, tobacco, cocoa, groundnuts, copra and palm kernels. |

 |
| Indian meal moth is the most common moth of stored dried foods and is the pest moth most often seen in homes. This moth usually enters homes in boxes or bags of infested foods. It appears in all points of the food processing chain from the grain silo to the food plant to the warehouse to the supermarket shelf and ultimately into restaurants, homes and other end-users of food products. This moth infests a wide variety of food items including flour, cereal, nuts, grains, chocolate, birdseed and dried pet foods. It is also present outdoors, occurring naturally and has been known to invade buildings from outside. |

 |
| Larder beetles are common pests of many industrial, commercial sites where animal protein is processed or stored. They may be found in homes feeding on dead insects or a rodent or bird carcass inside walls, attics, crawlspaces and basements. Foods attacked include ham, bacon, meats, cheese, stored tobacco, dried fish and dried pet food as wells as hides, skin, bones and dead insects. These beetles may be used by museums to clean flesh and hides off animal skeletons. |

 |
 |
| Both rice and granary weevils mainly attack whole grains, such as wheat, corn, barley and rice. These weevils may also be found infesting in such foods as macaroni and spaghetti when they get old. Rice weevils also feed on beans, nuts and cereals and have been observed sucking the juice from apples and pears. |
|
 |
 |
| Warehouse beetle derives its name from the fact that it is the most common species found in warehouses. It has the widest food preferences of any of these beetles, feeding on a wide variety of foods including cereals, candy, cocoa, cookies, corn, corn meal, fish meal, pet foods, flour, nuts, dried peas and beans, potato chips, pastas, spices, dead animals and dead insects. |

 |
| American cockroach thrives in warm, damp environments, such as sewers, steam tunnels, basements, crawl spaces, and boiler rooms. In southern states, it will also be found living and breeding outdoors. |
|
 |
 |
| Australian cockroach usually invades the attic or crawl space, where it finds conditions similar to that found within a tree hole (its natural habitat). Once populations grow large inside these sites, the cockroaches regularly venture down into the home. The occasional cockroach may wander into a home from harborage outside, but chronic infestations are most always associated with attic or crawl space populations. |
|
 |
 |
| Brown banded cockroaches are far less common than German cockroaches and are usually found in apartments, motels, and long-term care facilities. Like German cockroaches, these will be found in kitchens and bathrooms. However, because brown banded cockroaches can survive in drier areas, they will also be found in bedrooms, living rooms, closets, bookcases, etc. This behavior can make the brown banded cockroach a bit more difficult to control. |
|
 |
 |
| German cockroach will first locate itself in bathrooms and the kitchen, as close as possible to food and moisture sources. It spends about 80 percent of its time resting in cracks and voids. |
|
 |
 |
| Oriental cockroach commonly inhabits sewers and storm culverts and will enter buildings through floor drains. It will also live outdoors in firewood, leaf litter, sheds, dog houses, and similar locations. Indoors, the basement, crawl space, and occasionally the attic will be the primary harborage for this pest. |
|
 |
 |
| Smoky brown cockroach usually invades the attic or crawl space where it finds conditions similar to those found within a tree hole. Once populations grow large inside these areas, the cockroaches regularly venture down into the home. The occasional cockroach may wander into a home from harborage outside but chronic infestations are most always associated with attic or crawl space populations. |
