Black Gnats

What Are Black Gnats?

Black gnat is a common term used to describe several small, dark-colored flying insects that can become nuisances in and around homes. These often include:

  • Fungus Gnats: Mosquito-like insects that thrive in moist soil and decaying plant matter.

  • Black Flies: Typically found near running water; known for their biting behavior.

  • Biting Midges (No-See-Ums): Tiny flies whose bites can cause itchy welts.

  • Eye Gnats: Non-biting flies attracted to bodily fluids, potentially spreading bacteria

Common Types of Black Gnats

Fungus Gnats

These small, dark insects are often found around overwatered houseplants and damp soil. Fungus gnats feed on mold and organic matter, and their larvae can damage plant roots.

Black Flies

Breeding near streams and rivers, black flies are active during daylight hours. Their bites can cause swelling and allergic reactions in some individuals.

No-See-Ums

Almost invisible to the naked eye, no-see-ums, also known as biting midges, are notorious for their painful bites, often leaving itchy, red welts.

Eye Gnats

Attracted to the moisture of eyes, noses, and mouths, eye gnats can be more than just a nuisance; they may transmit bacteria, leading to infections like pink eye.

How to Get Rid of Black Gnats

Effective control of black gnats involves a combination of preventive measures and, when necessary, professional intervention:

  • Reduce Moisture: Fix leaky pipes, avoid overwatering plants, and ensure proper drainage to eliminate breeding grounds.

  • Improve Sanitation: Regularly clean drains, dispose of organic waste promptly, and keep kitchen areas tidy.

  • Use Physical Barriers: Install fine mesh screens on windows and doors to prevent entry.

  • Employ Traps: While traps can capture adult gnats, they are often insufficient alone due to the rapid breeding cycle of these insects.

Given the resilience and rapid reproduction of black gnats, persistent infestations may require professional pest control services. Contact your local Orkin branch to get help from trained exterminators who can identify the source of the problem and apply customized fly treatment methods tailored to your home.
