Female gnats only bite and suck blood from your skin in most cases. Unlike mosquitoes, gnat bites don’t break open the skin. Rather they cut open the skin to suck blood. However, they cause more pain. 

So when gnats bite humans, it causes minor to severe reactions to their bodies. 

Common symptoms include fever, headache, nausea, and swollen lymph nodes in the neck. It is also reported that people who are allergic to gnats showed severe reactions to gnat bites. 

In case you are bitten by gnats, avoid scratching the area as too much scratching can lead to a skin infection. You can apply antiseptic lotion to ease the pain and prevent any infection from developing.

Well, gnats are not only troublesome creatures for humans but also for our furry little friends, especially dogs

If you notice sudden bumps on your dog’s body or if the dog is feeling itchy and annoyed, then gnats are the reason behind them. 

These flying insects swarm around your pets and hide in their fur, and breed. In some cases, gnats lay eggs in open wounds and easily develop infections in their blood. 

In particular, if your dog is older, it might have a weak immune system, and it might find it hard to fight back the infections, and this can threaten its life. 

So it is highly recommended to identify and eliminate the breeding grounds of gnats and save yourself and your pets from the nuisance created by gnats. 


Most gnats varieties that bite are found outdoors. And Gnats tend to bite on uncovered skin, especially on the head, neck, forearms, hands, and legs. 

So connecting the dots, when you go outdoors, it is recommended to either cover yourself or apply some insect repellants. You can also apply some insect repellents on your pets, after consulting with a vet.
