Beyond bug spray, you can also wear clothing that helps to repel mosquitos

It’s true: Some people are more susceptible to mosquito bites than others.

Best personal mosquito repellents When choosing a repellent, Bentley; David Brown, technical adviser at the American Mosquito Control Association; and Dr. Mustapha Debboun, a retired medical and veterinary entomologist in the United States Army, co-editor of three books on insect repellents, and general manager Delta Vector Control District in Visalia, California, all recommend looking for repellents that have ingredients that are registered with the EPA and endorsed by the CDC, which include DEET, picaridin, oil of lemon eucalyptus, IR 3535, para-menthane-diol (or PMD, which is plant-based), and 2-undecanone. Brown is a fan of the EPA’s search tool that “helps identify the best repellent for the situation I will be in, which I know have been tested for both safe use and repellency.”

But “not all repellents are the same,” says Cope. “The gold standard for years and years is DEET, and many of the products that are out there are DEET-based.” While Cope, Brown, and Debboun say that the way DEET works is still being studied, it’s generally thought to block particular receptors on mosquitoes that prevent them from identifying a potential host for a meal. There are other theories that say that mosquitoes may not like the way DEET feels on their feet, keeping them from landing on your skin. Cope recommends looking at the percentage of DEET found in a formulation, and doesn’t recommend using anything more than 30 percent for the average person, with 5 to 10 percent being enough for one-to-two hours of exposure at a time. That’s because, says Brown, “The higher the concentration of a product does not necessarily provide stronger protection; it just provides longer protection” — but a higher concentration can be convenient if you don’t want to keep reapplying throughout the day. As far as other popular methods of mosquito control are concerned, Bentley says, “Citronella candles can offer some relief when used in combination with protective clothing and insect repellents, but products like these will not serve as a stand-alone repellent against hungry mosquitoes.”

OFF! Deep Woods Mosquito and Insect Repellent Towelettes $4 $9 now 56% off $4 One might think a spray is the best way to go, but Cope says that he personally prefers impregnated wipes (ones that are soaked in the solution and are ready to use). “They’re particularly good for kids because you can just do a better job of spreading it around and getting it where you want it to go,” as opposed to an aerosol can. These towelettes from Off contain 25 percent DEET and are recommended by Strategist contributor Maureen O’Connor, who has “hospitalization-level allergies to several North American insects.” “For on-the-go mosquito-repelling, nothing beats a wet wipe,” she writes. “It’s quick, easy, and can be deployed in a bathroom stall without anyone noticing.”

$4 at Amazon Buy $4 at Amazon Buy Best mosquito repellent products for your backyard Summit Mosquito Dunks $21 $22 now 5% off $21 There are products that people with outdoor space can buy that are specific only to mosquitoes, like Summit Mosquito Dunks, which kill the larvae before they become mature enough to bite. Cope recommends them because they contain a naturally occurring bacterium called Bti, or Bacillus thuringiensis israelensis, that when ingested by mosquito larvae causes their stomach to rupture. “It’s very widely used around the country, both by the municipal mosquito control and private-industry mosquito control folks,” says Cope. To use it, follow the label directions and place the biodegradable donut-shaped disc in any standing water. It floats on the surface and slowly breaks down, releasing Bti. “The reason it works is that mosquito larvae feed on bacteria and small particles in the water. They have a set of brushes on their mouth and they’re constantly sweeping the water into their mouth, and so they’ll pick up this product as it’s suspended in the water.”

$21 at Amazon Buy $21 at Amazon Buy Summit Mosquito Bits $15 $19 now 21% off $15 Bti, which is registered with the EPA, also comes in the form of corn-kernel-like granules that release the larvicide more quickly than the donuts, which dissolve over time. When used as directed, Bti is nontoxic to other wildlife, pets, fish, and humans.

To add an extra level of prevention, Bentley recommends using permethrin, an EPA-registered insecticide that’s commonly found in delousing products like Nix and is also used as a “tick-killing agent,” that Cope and Brown also vouch for. It comes as a spray that you apply on your shirt and pants, and some companies even sell clothing that’s already treated with it. “Permethrin-impregnated clothing can be very effective in preventing mosquito bites, and if you will be in the woods or heavy brush it is highly recommended,” says Brown. “It’s extremely effective at repelling all flying insects, in addition to ticks and mites.”

$15 at Amazon Buy $15 at Amazon Buy Shoo For Good The Camellia Lightweight Wrap in Cloud $140 $140 Actress Catherine Zeta-Jones swears by this cotton shawl from Shoo for Good that’s handwoven in Ethiopia and is “enhanced with odorless, invisible, EPA-registered Insect Shield protection,” according to the product description. (Insect Shield also makes its own permethrin spray and a line of permethrin-treated clothing.) “I am somebody who gets bitten by mosquitoes all the time,” says Zeta-Jones. “It really, really repels. It also doesn’t have any kind of smell — unlike bug spray or even other pashminas, this is odorless.” Like other permethrin-impregnated clothing, this one can be washed up to 70 times before it loses its efficacy.

Cope adds that a floor fan “even on low” can keep them from landing on or around you. (A ceiling fan won’t do the trick, he says, “because the mosquitoes are down low”), so one that’s on the ground, like this highly reviewed fan from Vornado, is a better option.

$80 at Amazon Buy $80 at Amazon Buy Best treatments for mosquito bites Dixie 3 oz. Cups, 600 Count $24 $24 If after taking all of these precautions you do end up covered in bites, you’ll want to treat it. Our experts agree that the most important thing to remember is to not scratch the bite. “Scratching can open the skin and allow bacteria to enter and cause an infection,” says Brown. Bentley, echoing what your parents likely told you when you were a kid, agrees: “Scratching a mosquito bite only makes it worse.” For those who just can’t stop scratching Cope recommends covering them with Band-Aids. And applying ice or a cold pack to the bite can go a long way toward relieving itching and irritation. Here’s a little hack from Cope that he finds particularly helpful: Fill up a Dixie cup halfway with water and freeze them. As soon as you get a bite, “get one of those and tear the cup off and do an ice massage on it,” he says. “That’s much more effective than just an ice pack for some reason.”

$24 at Amazon Buy $19 at Walmart Buy Cortizone-10 Plus Ultra Moisturizing Cream $7 Bentley and Debboun also recommend using a hydrocortisone cream, which can help soothe the itch. Always follow label directions, and, Bentley warns, “If symptoms increase, consult a physician.”
