Do Gnats Bite? If so, How Deadly The Bites Are?


The one-line answer is, yes!

So the answer to “Do Gnats Bit” is Yes, but not all the species of gnats bite. There are some spices that do bite, especially the female gnats.

Gnats don’t bite like the other insects like a mosquito or a bed bug. Gnats usually open up your skin using their sharp cutters and then inject an anti-clotting substance into your skin so that they can devour as much blood as they can before the wound closes.

Due to this reason, gnat bites are actually more painful than a mosquito bite.

When a gnat bites, you will feel a burning sensation. Depending upon the severity of the bite, you can either have a small reddish spot or a bigger spot followed by a lot of itching, burning sensation and allergic reactions.

The people who are more prone to gnat attacks are the farmers and the individuals who perform livestock farming.

If you live around such areas where you can spot gnats flying, keep an insect repellent spray handy to protect yourself and your animals.

Do Gnats Bite? What Kind Of Diseases Do Gnats Spread?


The biting species of gnats tend to transmit a disease known as Bluerounge Virus to farm animals including cows, goats, sheep, buffaloes etc. The infected animals suffer high fever, swollen face. Also, in such infection their tongue tend to get slightly bluish in color, hence the disease got its name “Bluerounge Virus”

Other than infecting the livestock, gnats do not carry diseases and spread in the same way mosquitoes do.

Moreover, eye gnats spread pinkeye which is not at all severe. It is common and can be cured easily. You don’t have to worry much about it.

However, the biting gnats cause itching sensation and excessive scratching can result in skin rashes and other harmful skin infections. Therefore, to prevent yourself from scratching and to soothe the skin, apply an antiseptic lotion or gel. You can also apply fresh aloe vera gel, it will treat the burning sensation and itching very well.
