Experts share mosquito bite prevention tips for the summer

Mosquito experts who study these bugs for a living follow the same handful of habits every summer, and skipping standing water is at the top of the list.

Quick Take

Entomologists and public health agencies agree on a core set of proven mosquito-bite defenses, not just one trick.
Dumping standing water breaks the mosquito breeding cycle before eggs can hatch.
Experts wear long sleeves and pants even in hot weather and choose repellents with proven ingredients like DEET.
Avoiding dusk and dawn outdoor time cuts exposure during peak mosquito activity.
Rising mosquito-borne illness cases make these basics matter more than ever this year.

Why Standing Water Is Public Enemy Number One

Every mosquito expert interviewed by Time starts in the same place: standing water. Once they find it, they dump it immediately. Mosquitoes lay eggs in even small pools, from bottle caps to gutters. The Centers for Disease Control and Prevention (CDC) lists mosquito control, indoors and outdoors, as a core prevention step, and that starts with removing anywhere water can collect.

Experts don’t stop at dumping. They scrub the sides of containers they plan to keep, because eggs can cling to the surface even after the water is gone. Then they flip those containers upside down so rain can’t refill them overnight. This single habit, repeated weekly through summer, does more to cut backyard mosquito numbers than almost anything sprayed from a can.

The Vermont Department of Health backs this approach with the same guidance given to families nationwide: check yards for anything holding water after rain, from clogged gutters to unused planters, and empty it regularly. It’s not glamorous advice, but it targets mosquitoes before they can bite anyone.

Repellent Choice Is Not Guesswork for Experts

Entomologist Nina Markowski favors products with 20 percent DEET, a concentration high enough to last through a long afternoon outside without constant reapplication. That lines up with the Cleveland Clinic’s advice to apply repellent directly to exposed skin and focus on areas like ankles, wrists, and the neck, where bites are most common.

The CDC’s official list narrows the field to Environmental Protection Agency (EPA)-registered repellents, a label that means the product has been tested for both safety and effectiveness. Experts skip novelty gadgets and wristbands with no track record. They also treat clothing and gear with permethrin, a step the CDC recommends alongside skin repellent for extra protection during high-risk outings.

Clothing Choices That Outlast Comfort

Markowski wears long pants and long sleeves even when temperatures hit 95 degrees, a habit that sounds miserable but works. Loose, long clothing creates a physical barrier that stops many bites before repellent is even needed, according to CDC guidance on protective dress. Doctor Peter Hotez has made the same point publicly, noting that covering skin during peak hours meaningfully lowers exposure to mosquito-borne disease.

Color and fit matter too. Tightly woven, light-colored fabric is harder for mosquitoes to bite through and less likely to attract them compared to dark, loose-knit material. Combined with repellent underneath, this layered approach is what separates casual bug spray users from people who study mosquitoes for work.

Timing Outdoor Plans Around Mosquito Behavior

Mosquitoes are most active from dusk to dawn, and experts plan around that window rather than fighting it. Scheduling yard work, walks, or barbecues outside those hours cuts exposure without spending a dime on products. Arizona State University researcher Silvie Huijben notes this timing shift alone measurably reduces bites, since activity levels vary by species but the dusk-to-dawn pattern holds broadly true.

This habit matters more now given the stakes. Mosquito-borne illness cases have been climbing, and health officials continue flagging risks tied to West Nile virus and other diseases spread by mosquito bites. None of these steps require special equipment. They require consistency, the same kind experts bring to their own backyards every single summer.

Insect repellents can help prevent insect bites when used properly. Use only EPA-registered repellents, and read the product label before use. If you have questions about insect repellents or bites, call the Poison Help line at 1-800-2222-1222.#bugspray #children #safety pic.twitter.com/0UeAPuCqZV

Taken together, the pattern is simple: remove breeding sites, cover skin, use tested repellent, and avoid peak hours. No single step does all the work, but stacked together they explain why the people who study mosquitoes for a living rarely complain about getting bitten.
