Wikipedia states “A gnat is any of many species of tiny flying insects in the Diptera suborder Nematocera, especially those in the families Mycetophilidae, Anisopodidae, and Sciaridae.” When referring to the term ‘gnats,’ you are actually referring to the whole group which consists of numerous species.

Yes, there are various types of gnats, each with their unique behavior and habitats.

Sometimes, you can presume fruit flies for gnats because of their somewhat similar appearance. It is a very common mistake people make differentiating fruit flies and gnats.

Gnats have a small, slender body with long legs and antennae. They are not more than two-tenths of an inch in size. Adults gnats have a lifespan of approximately one week. The males usually move in groups called ‘ghosts.’

These ghosts are usually spotted during dusk. Males swarm until a female enters to mate.

At this point, you might be wondering – how do these tiny creatures enter the house or find a place in the backyard?

Where do gnats come from?

Moisture is essential for gnat breeding. After mating, the females lay eggs on water or moist surface to hatch. These hatchings then transform into larvae. Subsequently, these larvae feed on the organic matter before pupating. Finally, these pupas become winged adults.

It is hard to tell where no-see-ums come from as you cannot spot their breeding grounds. You only see them as winged adults when they become annoying.

Remember, gnat problems occur due to moist surroundings. It could a water puddle, moist soil in indoor plant pots; gnats will use these places to breed and be a nuisance to you. So, keep a lookout for these conditions.
