Bed bugs are small, brownish, flattened insects that feed on the blood of humans and other warm-blooded animals. They often hide in the small crevices of mattresses, box springs, bed frames, and headboards.
There are several different species of ants found in the U.S., but they each have the same three distinct body regions: the head, thorax, and abdomen, as well as the antennae. Ants are especially attracted to sweets, although they will eat any kind of food. They are social insects, meaning they live in colonies and rarely travel alone.
Most roaches are about 0.7 inches to 3 inches long, and they are reddish-brown to black in color with oval-shaped bodies. Since roaches are nocturnal insects, you are most likely to spot one at night.
There are over 2,050 different species of rodents. Among some of the most common are mice, rats, and moles. Such pests are quite an inconvenience, and in some cases, extremely dangerous.
There are thousands of species of spiders, but only a handful are actually harmful to humans. Dangerous spiders commonly found in the US include the black widow and the brown recluse. All spiders have eight legs and most have eight eyes, although some have fewer.
Termites pose a serious threat because they can cause severe structural damage in a fairly short amount of time, and they often go undetected until it is too late. Termite infestations cost Americans more than $5 billion each year in damages and are rarely covered by insurance.
Earwigs are medium-sized, nocturnal insects. They feed on other insects, vegetation such as moss or fungi, decaying organic material, or occasionally, greasy food that has been left out for a while. Earwigs hide out in dark, damp places, so during hot and dry weather they may seek shelter somewhere in your home.
Silverfish are shiny gray or silver insects that are thought to be some of the oldest insects in the world. They are most active at night, which is when they are typically spotted. Silverfish are not harmful to humans, although they may cause allergic reactions in some people.
Mosquitos are flying, biting pests that are especially prevalent during the warm Summer months. They feed on blood in order to develop eggs, and human blood is their meal of choice. Mosquito bites create red, itchy bumps that irritate the skin.
Beetles are the most common type of insect and are very diverse with more than 300,000 different species. While beetles primarily live outside, they sometimes invade homes at the end of Summer in search of shelter.
Weevils are very small beetles that are attracted to dry foods, such as wheat and stored grains. Because of this, weevils often infest pantries and can be found in things like nuts, seeds, and cereals. Although they may cause food spoilage, weevils themselves are not toxic to humans.
The most commonly encountered wasps include hornets, paper wasps and yellow jackets. Stings from these wasps can be extremely painful, and unlike bees, they can sting more than once.
