Types of Small Black Bugs (With Pictures) – Identification

Small Black Bugs

No one wants to find small black bugs in the house. Small black insects crawling, scurrying, or slithering across a floor could be a beetle, spider, black ant, cockroach, or pillbug. But there are also tiny black bugs that are difficult to spot because they lurk in crevices or only come out at night. In some cases, the only signs of little black bugs are red, itchy, bite marks they leave on your skin.

Knowing how to identify small black house bugs is crucial if you want to eradicate them. Some types of black beetles, weevils, and ants are attracted to foodstuffs in your pantry. Black flying bugs could be a sign of a plant infestation or rotten food in your kitchen. However, certain black spiders like the black widow are dangerous arthropods that can inflict a nasty bite.

Many people refer to all dark brown or black house pests as bugs. However, not all insects are classified as true bugs.
