Bugs commonly found in the home include several varieties of ants and termites, spiders, bed bugs, and cockroaches. The exact distribution of species of bug is dependent on the house’s geographical location and local climate.

According to Pestworld.org, the official website of the National Pest Management Association, common household insects include ants, bed bugs, cockroaches, flies, termites, and spiders. There are a plethora of varieties of ant that can be commonly found in the home including Acrobat, Carpenter, Field, Harvester, Thief, and Yellow ants. These ants can pose a threat by stripping electrical wires, burrowing into wood, and stinging if disturbed.

Bed bugs are also commonly found in homes and are not restricted to infesting beds; they can also infest light switches, skirting boards, and carpets. They are hard to prevent and treat if an infestation occurs.

The most commonly found cockroaches are American, Brownbanded, Oriental, and German cockroaches. They have been found to carry over 33 types of bacteria and six species of parasite. House, Fruit, and Horse flies are the most common household flies. All three species carry many types of bacteria and female Horse flies can leave quite painful bites on humans.

Termite species found in homes include Subterranean, Drywood, Formosan, and Conehead termites. Termites will eat through wood and can aggressively damage structures if left untreated. Brown Recluse, Long-bodied Cellar, Common House, Jumping, and Hobo spiders are often found in homes. Most species of spiders are no threat to humans or their homes, but species like Hobo, Brown Recluse, and Jumping will bite if they feel threatened.
