How to Get Rid of Gnats

It is normal to get worried when you find strange insects flying and crawling around your home. Aside from the fact that their infestation may be problematic to you, your pets and other members of your home, you may fear that they are dangerous to your health. Gnats are some of the pests that like to infest human dwellings in large numbers. If you are looking for an effective method to manage a gnat infestation, then you are in the right place. This post will provide you with tips and a few effective methods to get rid of this insect and prevent future reinfestation. Scroll down for details.


What Are Gnats?

There is no unanimity among scholars and scientist as to what constitutes a gnat. While most scientists argue that they are a group of non-biting insects, others stated otherwise. However, gnats are a group of different species of small flying insects usually in the family Anisopodidae, Mycetophilidae, and Sciaridae as well as in the Diptera suborder Nematocera. The insects that fall within this category includes both biting and non-biting ones.

Furthermore, gnats mostly fly in large numbers and they are mostly seen in summer. They usually create their dwellings on wet soil or in places where there is water. This is especially because the females lay their egg closed to aquatic vegetation or on water. Gnats lay so many eggs at a time as a single female can lay up to 1,000 eggs in a lifetime. This makes it even difficult to get rid of the insects when they infest your home. The eggs usually hatch over several days with the larvae appearing like small worms.

After this stage, the larvae with pupate for a few days and then metamorphosis into winged adult gnats. Gnats have a short lifespan as they only last about 7 to 10 days in their adult stage.


Are Gnats Harmful to Human Health?

As already mentioned, there are there two different types of gnats – biting and non-biting species. Adult biting gnats such as black fly also known as buffalo gnat may bite humans. It is reported that their bite is as painful as that of fire ants. Another type of gnats called biting midges may also bite humans and feed on their blood. Biting midges are also referred to as sand flies and they are really small and somewhat hard to identify with bare eyes.

Some gnat larvae are aquatic but others are free living. These larvae usually feed on plants but you may find a few that are carnivorous in nature. The infestation of your home by the latter may be problematic and may even be harmful to your health if you are allergic to their bites. Plant-feeding larvae also known as fungus gnats are considered pests as they may cause little or no harm to your plants. However, in large numbers, gnat larvae may stunt the growth of plants and reduce their productivity significantly.

For this reason, it is advised to take active steps to get rid of fungus gnats if you manage a greenhouse, a garden, or if you keep potted plants in your home. Another type of gnats known as fruit flies feed on fruits and may cause damage if you store some in your home. Non-biting gnats, on the other hand, don’t harm humans and they don’t damage plants but they can constitute a nuisance in your home.

Generally, gnats can bite your and other members of your family which may have a negative effect on your health. It is reported that some gnats are vectors that may transmit diseases from one victim to another thus causing harm to human health and that of their livestock.


Benefits of Gnats

Just like other creatures in the ecosystem, gnats play important roles. It is reported that some pleurothallis orchids in South America are pollinated by tiny gnats. Also, after gnat eggs hatch in water, the pupa will rise to the water surface where they serve as a nutritious meal for fishes.
