It seems as though the mosquitos are out in force! Biting insects and even pollinators are attracted to humans because of our sweat! Find out why, how to avoid mosquitoes and cut back on the population in your yard naturally, and discover some mosquito bite remedies.
The summer heat really brought out the mosquitoes. You’ll also see other biting or stinging insects as well.
Unfortunately, these insects often go for humans. No, it’s not just to bother us. Mainly, insects in late summer are attracted to our sweat! Why? They need the sodium in sweat to reproduce. Even the pollinators such as bees and butterflies need more than their daily diet of nectar and are attracted to sodium.
Most of us don’t mind the pollinators, but the mosquitoes are another story. Keeping those little fiends away is not only a matter of comfort but can be a matter of disease prevention such as West Nile virus. Just keep in mind this virus is very rare and even those who get it usually have mild flu-like symptoms.
Interestingly, it’s not all mosquitoes that feed on blood, though: male mosquitoes only drink nectar. Why do the females bite? As well as taking in sodium, they are nourishing their developing eggs with protein-rich blood. To that end, female mosquitoes prefer to bite ankles and wrists, where blood vessels are nearer to the skin’s surface. Ever noticed where you get bitten?
Why Do Mosquito Bites Itch?
When a mosquito bites you, it injects a small amount of saliva into the wound to stop your blood from clotting. Our bodies react to this foreign substance and, in defense, produce a protein called histamine. Histamine triggers the characteristic inflammation seen around mosquito bites, as well as the itching.
Avoid Bites in the First Place
A higher body temperature and more sweat make you more likely to be bitten. Since sweat attracts mosquitoes, a first step is to wash off any sweat and take more showers. Second, keep your body temperature down or try to go outside in the morning before it gets too hot and humid.
Place a barrier between the skin and mosquitoes. Wear loose, light-colored pants and long-sleeved cotton shirts. If it’s a truly infested place, add a head net.
Reduce the mosquito population in your yard. Eliminate mosquito breeding sites on your property. They need standing water to breed, so empty those puddles, old cans, buckets, and plant pots. If you have a pond, don’t worry—dragonflies love ponds, and they are a big mosquito predator. Just don’t hang around standing water yourself!
Citronella candles are not proven to work in studies, however, citronella smoke repels mosquitoes.
Add a bat house to your home! Did you know that one small brown bat can eat as many as 600 mosquitoes in 1 hour?
If you are camping outside, use mosquito netting around bedding. Spraying the netting with insect repellent is a good idea.
Mosquitoes hate basil, lime basil, thyme, lemon eucalyptus, catnip, monarda, and coriander. Crush their leaves and rub against your skin for added protection! Read more about plants that repel mosquitoes.
Spray yourself with an effective, safe mosquito repellent. (See below.)
Effective Natural Mosquito Repellents
Garlic oil rubbed onto the skin has proven to be effective in research. Just rub the garlic juice directly on the skin. Eating garlic has not been shown to be effective at repelling mosquitoes.
Catnip or catnip oil is more effective than DEET at repelling mosquitoes, according to laboratory research conducted by Chris Peterson, an entomologist with the U.S. Department of Agriculture Forest Service, and Joel R. Coats, former chair of the Department of Entomology at Iowa State University.
Oil of lemon eucalyptus (or PMD, the man-made version) can be very effective. Some repellents in the United States that contain it include Repel Lemon Eucalyptus and Off! Botanicals.
Many claim that rubbing apple cider vinegar on your skin helps to repel insects. If you take in enough apple cider vinegar by putting it on foods you eat, you’ll develop a body odor that will repel insects, including black flies. One great and refreshing summer drink for this purpose is switchel, made from apple cider vinegar.
Thyme essential oils have been found to repel mosquitoes as well as or better than DEET, and that thyme volatiles lasted as long as DEET.
Geraniol oil, which comes from the monarda plant, is highly repellent to mosquitoes. Geraniol is the active ingredient in some commercial natural mosquito repellents.
DEET has been around for more than 50 years, and the EPA claims it’s safe if “used as directed.” We prefer to avoid a neurotoxin but if you do use DEET, know this: There’s no justification for using DEET in high concentrations. Use no more than 25 percent DEET. Unlike the SPF rating in sunscreens, higher concentrations of DEET don’t mean more protection.
Picaridin, a derivative of piperidine, a chemical related to black pepper, has been used in Europe since the late 1990s. In this country, Cutter Advanced was the first picaridin product to hit the market.
Avon/IR-3535 is the active ingredient in Avon insect repellents (and some others as well). It lasts for about 2 hours. It can cause eye irritation if you spray it there by accident, but is otherwise very safe.
Best Way to Relieve Bites and Itching
It helps to ice the area of the bite to constrict the capillaries near the skin’s surface and reduce swelling.
If you are going to use a topical cream, stay away from caladryl and calamine lotions for mosquito bites; it’s better to apply a low-potency hydrocortisone and be patient.
Remember: Do not scratch the bite; this will only make it worse. For itchy bites, rub on meat tenderizer or lemon juice.
A paste of mashed garlic can also help stop bug bites from itching.
White vinegar is another remedy for relieving the itch of insect bites. Apply it in full strength. Don’t use vinegar if the area is raw. See more household uses for vinegar.
A paste of baking soda and water can provide much-needed relief to bug bites. Learn more about the countless household uses for baking soda.
Oatmeal can also help to provide itch relief—not only for bug bites.
Some people have luck with high doses of vitamin B1 (100 milligrams, two or three times a day), but it doesn’t work for everybody.
If you have an intense reaction to mosquito bites, consult your doctor.

I have a female friend from England and the bugs zero in on her from all directions when here. Immediately when bitten she applies clear nail polish and is relieved. Cheap / quick remedy .
For some reaso in the buggy VT, people that visit attract the blood suckers and are flying all around them. For some reason I don't attract them. Occasionally they will fly around my ears. Figured it was due to the heat given off by the body and insects like heat. Guess my body chemistry is rather neutral.
I'll warn you that this is going to sound gross but it does seem to provide relief from itchy bites. When our kids were little we traveled to the Yukon where our daughter particularly attracted the mosquitoes. She had a bad reaction and the swelling was nasty. Fortunately, we were in a museum where the lovely indigenous lady who admitted us noticed our daughter's arms. She told me to have her rub her spit on the bites. Apparently, there is something in our saliva that helps break down the protein that causes the itch. Although it sounds disgusting, it did help her. I've tried it on myself since and it relieved the itch quite quickly - sometimes it needed another application. Perhaps it's an even better solution to paying for chemical solutions, especially if there isn't a pharmacy nearby.
Very interesting article. Want to have LOTS of tomatoes this year - to give to friends, to can for the winter, and perhaps to sell within the neighborhood. Thanks for all the advice. Will cherish it.
Simply put, in July and August here in Pine, AZ—our monsoon season, skeeters are prevalent…wear long pants, long sleeved shirts and socks. We get through skeeter season easy just wearing proper clothing protection. Loved all the ideas in this article though!
