Cockroaches produce odor secretions from different points in the bodies which can affect the flavor of many different foods. When cockroach populations are high, these secretions may result in a characteristic odor in the general region of the infestation.

Drywood termites generally live in undecayed wood which has very low moisture content. Unlike subterranean termites they don’t require any contact with the soil in order to live.

Infestations of bed bugs indicate their presence by leaving blood stain, smears on walls, bedding, curtains, and other light colored surfaces.

In food storehouses, rats eat, destroy and/or contaminate with excrement, urine, and hairs an enormous amount of grain, flour, cereals, sugar, fruit, nuts, meats, animal feed, pet food, and many other types of food products. The same type of damage can occur in home pantry.

Some ant species feed on a wide variety of food items, while others typically feed on a smaller range of foods. Food preferences may also change significantly during the course of any season, especially for outdoor  ants or depending on the needs of the ant colony.

Periods of high egg production usually require foraging ants to bring proteins to the queen, while at other times foragers may prefer to gather sugars or greases for their own energy needs or to promote larval growth.

  Honeybees can become serious pests when it makes a nest in or on a structure. One of the  most serious problems happen when a swarm of wild bees find a small opening in an exterior wall or chimney,  and then nests in a wall void or some other interior area of a structure.

Bed bugs may be found in seemingly unlikely places such as cracks in the floor under carpeting, behind electrical switch plates, in folds of draperies, in ovens or broilers, and in the motor compartments of refrigerators.

Termites display many forms of cooperative behavior, including nest-building , tending the eggs and young, foraging for food, and grooming other members of the colony.

Drywood Termites entrance into wood is generally made from a crack or crevice which the termites can enter through before boring into the wood. It can be a crack in the wood itself or may be the joint between two pieces of wood.
