Gnat bites may be dangerous and should be treated as soon as there is a problem noticed. Most of the time, gnat bites will not cause serious harm, but there is always the potential. Many times, people may not even realize they have been bitten by gnats. However, there are times when gnat bites will become more complicated.

The best advice to keep gnat bites from becoming big problems is to wash the area that was bitten. This may not need to be done right away, but the sooner, the better. In some cases, simply taking a daily shower can help cut the risk of infection down substantially.

One of the biggest problems with gnat bites comes from bacterial infection. The insects do not live or operate around extremely clean environments, and even their small feet can pick up harmful microscopic organisms. Therefore, bacteria can be introduced to a wound even in the smallest of ways. Bacterial infections may stay isolated to the area that was bit, or may spread internally to other areas of the body. In some cases, they can become significant health problems needing professional medical attention.

This is especially true with open wounds. Gnats, many of which need blood meals in order to survive, are very much attracted to open sources of blood, where there is very little effort needed to get the nourishment desired. A constant picking by a horde of gnats can cause the wound to fester for weeks after it would normally otherwise. That festering, to one extent or another, is caused by gnat bites. The longer the wound stays open, the more prone to infection it becomes.

Pets and other animals, more so than humans, are prone to gnat bites in open wounds. Humans can escape inside, which does a good job at keeping most gnats away. Pets, on the other hand, often stay outside a substantial portion of the day, if not the entire day. If there is an open wound, the best way to care for it is to make sure it is protected with a bandage that is changed often.

To help keep gnat bites from becoming infected, it is also recommended to dab the area with an antiseptic and perhaps apply an anti-itch cream. Gnat bites often itch and scratching at them can lead to further difficulties and keep the wound open longer. Anti-itch creams do a good job helping take the urge to scratch away.

I am so itchy from gnats and gnat bites. I lived in housing and all pest control does is to place those insect inhibitors around; they don't work for gnats.

I am so freaked out, and ready for the nut house. I tried vinegar and soap detergent, baking soda in the sink drain, clorox in sink drain about two gallons, what about ammonia.? The building is old, built in 1929 and has about 75 units.

I suppose they are in the wall and window cracks. It just makes me so nervous. Housing tells me that a fogger is not allowed in this state. Baloney.

I had a cousin that had a pretty common gnat bite. After a few days and much scratching, it got infected. She ended up in the hospital because the infection was so serious. Gnat bites should be treated immediately if the area looks like it is getting infected.

Use five drops orange oil, five drops eucalyptus oil and five drops of patchouli oil. Mix with four oz of aloe vera gel and any unscented lotion. Gnats won't land on you or bite you. works for mosquitoes, too. I substitute spf 30 sunblock unscented for the lotion so I don't get sunburned and bug bitten at the same time. This works.
