Ants have a habit of raiding stored food, damaging indoor structures, causing damage to agricultural crops either directly or by aiding sucking pests.
Bed bugs can cause a number of health effects, including skin rashes, psychological effects, and allergic symptoms.
Although they specialize on Acer seeds, they may pierce plant tissues while feeding.
Carpenter ants can damage wood used in the construction of buildings.
The house dust mite (sometimes referred to by allergists as HDM) is a cosmopolitan guest in human habitation. Dust mites feed on organic detritus such as flakes of shed human skin and flourish in the stable environment of dwellings. House dust mites are a common cause of asthma and allergic symptoms worldwide. The mite’s gut contains potent digestive enzymes (notably proteases) that persist in their feces and are major inducers of allergic reactions such as wheezing. The mite’s exoskeleton can also contribute to allergic reactions.
Adult beetles usually lay their eggs in air ducts, in closets, under furniture, or under baseboards. Once hatched and until they pupate into adults, the larvae hide in dark, undisturbed areas and feed on organic material. The larvae are thus responsible for the damage of various items, such as furniture, clothing, blankets, furs, and carpets.
Fleas feed on a wide variety of warm-blooded vertebrates including dogs, cats, humans, chickens, rabbits, squirrels, rats, ferrets, and mice. Fleas are not simply a source of annoyance, however. Flea bites generally cause the formation of a slightly raised, swollen itching spot with a single puncture point at the center.
Larvae can infest a wide range of dry foodstuffs of vegetable origin, such as cereal, bread, pasta, rice, couscous, flour, spices or dried fruits and nuts.
They are known to invade homes for food and occasionally shelter.
In feeding on blood, some of them transmit extremely harmful human and livestock diseases, such as malaria, yellow fever, and filariasis.
The Center for Disease Control does list nearly a dozen diseases directly linked to rats.
They scavenge for food and reproduce very quickly.
In order to thrive, cockroaches need a place to hide. They prefer warm places and a relatively high humidity if possible; they also need a source of food/liquid.
Silverfish are pests because of their consumption and destruction of property.
Spiders are arthropods that have eight legs and chelicerae with fangs that can inject venom. (Wolf Spider shown)
Termites live in colonies that, at maturity, number from several hundred to several million individuals. Termites communicate during a variety of behavioral activities with signals. Colonies use decentralised, self-organised systems of activity guided by swarm intelligence which exploit food sources and environments unavailable to any single insect acting alone. A typical colony contains nymphs (semimature young), workers, soldiers, and reproductive individuals of both sexes, sometimes containing several egg-laying queens.
Ticks are ectoparasites (external parasites), living by hematophagy on the blood of mammals, birds, and sometimes reptiles and amphibians. Ticks are vectors of a number of diseases, including Lyme disease, Q fever (rare; more commonly transmitted by infected excreta), Colorado tick fever, Rocky Mountain spotted fever, African tick bite fever, tularemia, tick-borne relapsing fever, babesiosis, ehrlichiosis, Tick paralysis, and tick-borne meningoencephalitis, as well as bovine anaplasmosis and probably the Heartland virus.
Yellow Jackets (Wasps)
May sting or bite. Parasitic with other insects like bees.
