Use Environmental Protection Agency (EPA)-registered insect repellents containing DEET, picaridin, IR3535, Oil of Lemon Eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone. EPA's helpful search tool can help you find the product that best suits your needs. Always follow product instructions.
Apply mosquito repellent to all areas of exposed skin
Apply repellent to all areas of exposed skin, after you apply sunscreen. Avoid putting repellent near the eyes and mouth, or over open wounds, broken skin or abrasions. Always follow the product label instructions. It's important to reapply repellent after swimming.
In order to protect against vector-borne illnesses such as West Nile Virus and Lyme Disease, the Centers for Disease Control and Prevention (CDC) recommends the use of DEET-containing products (at concentrations of at least 20%) to repel biting pests such as mosquitoes and ticks for several hours.
People that have left DEET products on their skin for extended periods of time have experienced irritation, redness, a rash, and swelling. People that have swallowed products containing DEET have experienced stomach upset, vomiting, and nausea. Very rarely, exposure to DEET has been associated with seizures in people.
Lemon eucalyptus essential oil is a natural insecticide that the CDC has approved. Lemongrass, lemon balm, and peppermint can be sprayed on your skin to keep mosquitoes at bay. Other essential oils that can be used to repel mosquitoes include citronella, rosemary, and lavender.
Yes: DEET. A repellent with DEET tells mosquitos to buzz off loud and clear. You'll need one with at least 20% DEET to protect your skin for several hours at a time, although more than 50% doesn't work any better (kids should use 10%-30%).
DEET is a widely used repellent that deters pests by making it harder for them to smell humans. Despite being effective, it has faced controversy over potential health and environmental impacts, including skin irritation and toxicity concerns. Some countries have even banned DEET due to these risks.
Picaridin: This chemical hasn't been in use as long as DEET, but it's been shown to be just as safe and effective, and it has fewer downsides. A product with 20 percent picaridin can give you up to 14 hours of protection against mosquitoes and ticks, per an EPA-approved label.
There is no reliable evidence that deet causes cancer.
A Swedish study did find that men who used insect repellent for 115 days or longer faced an increased risk of developing testicular cancer.
Studies have shown that Picaridin is effective, safe and has fewer unpleasant qualities than DEET. Picaridin is odorless, does not melt plastics, or feel oily on skin. Studies show that Picaridin is as effective as DEET when used at the same strength. Picaridin is available in brands such as Cutter and AVON.

Dengue viruses are spread by the bites of infected Aedes species mosquitoes. In the United States, public health authorities in Puerto Rico and US Virgin Islands have declared dengue outbreaks. Local transmission of dengue has also been reported in 2024 in California, Florida, and Texas.
Mosquitoes are turned off by several natural scents, including citronella, peppermint, cedar, catnip, patchouli, lemongrass, lavender and more. You can add some of these plants to your landscaping to fend them off.
DEET is a reliable and highly effective insect repellent. The chemical has been in public use since 1957. The repellent is sold under numerous brand names and comes in lotion, spray and many other forms. Concentrations of DEET range from about 5% all the way up to 100%.
If used improperly, such as if someone swallows it or applies too much, DEET can cause severe health effects like seizures, low blood pressure, uncoordinated movements or death, Dr. Kennedy said. But those cases are rare — seizures, for example, occur only once in every 100 million uses, according to the E.P.A.
Products containing DEET are typically very low risk when people use them correctly. DEET can cause skin irritation in some people, but this is rare. Some people who have used high strength DEET or had exposure to DEET over a long period have experienced adverse effects. DEET is also toxic if ingested.
Did you know that vitamin B can lower your risk of insect bites? Some people seem prone to being bitten by insects, particularly mosquitoes and when abroad. Many dermatologists now recommend that the skin can be made much less attractive to biting insects by taking Vitamin B supplements whilst at risk.
For more than 60 years, DEET has reigned as the undisputed champion of insect repellents. No longer. There's now a potentially better alternative on the market: picaridin. Both DEET and picaridin are proven to be effective at fending off ticks—and are superior to other repellents when it comes to protection time.
Other factors such as blood type and breathing patterns also seem to play a role. Type O blood appears to attract the pests. So does breathing heavily — such as after a workout — which exudes more carbon dioxide around you, which attracts mosquitoes.
