The big mosquito showdown

Mosquito lasers, drones, sprays and more: every option, scored

Q: What actually works to prevent mosquito bites?

CDC recommends EPA-registered repellents with one of six active ingredients: DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone. CDC's Yellow Book adds that the effectiveness of repellents not registered with EPA, including some natural ones, is unknown. Skin repellents do work, but they don't last: UF/IFAS puts DEET at one to three hours of protection in typical conditions and says sweating or swimming shortens it. MosquitoNoBite takes a different route: it's a dietary supplement made from a proprietary blend of organic ingredients, intended to naturally dissuade mosquito interest, with no smell and no unwanted chemicals. Its active ingredient is a compound already found in the human body. It isn't an EPA-registered repellent. Sources: CDC Travelers' Health, CDC Yellow Book, EPA ingredient list, UF/IFAS.

Q: Does wearable netting work?

A net is a physical barrier on the skin it covers. CDC advises long sleeves and long pants, recommends sleeping under a mosquito net when you're outside or in a room without screens, and says permethrin-treated clothing keeps working after multiple washings. A mesh body suit or head net only protects what it covers, so it suits fishing and gardening better than a barbecue. Source: CDC Travelers' Health.

Q: Do oral mosquito repellents, like garlic or vitamin B, work?

CDC's Yellow Book calls ingesting vitamin B or garlic ineffective, and the American Mosquito Control Association says controlled lab studies found no impact from garlic or vitamin B12. A University of Wisconsin study of vitamin B supplements also found no effect on how attractive people were to mosquitoes. MosquitoNoBite is a dietary supplement, not an EPA-registered repellent, so where mosquito-borne disease is a real risk, follow CDC and use an EPA-registered repellent. Where you just want fewer backyard bites, the empty-bottle guarantee lets you test MNB without risking the purchase price. Sources: CDC Yellow Book, AMCA, Ives and Paskewitz.

Q: Do ultrasonic repellers and mosquito wristbands work?

CDC's Yellow Book says sound-emitting devices and repellent-impregnated wristbands are ineffective. Lasers and drones are a different category because they try to kill mosquitoes rather than repel them, but the lesson carries over: if there's no money-back option, ask for independent test data before you buy any gadget.

The short answer

There are eight realistic ways to avoid a mosquito bite, and they could hardly be more different. EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellent sprays have the strongest proof, but UF/IFAS (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab) puts DEET, the benchmark ingredient, at one to three hours of protection in typical conditions, and less when you sweat. Mosquito lasers and drones are the most fun to watch, and in the coverage we reviewed neither has published independent test results. MosquitoNoBite is a capsule with an expected price of $49.95 for a 90-day bottle, so two cover a six-month season for under $100 with free shipping, and there's nothing to set up, charge or reapply, plus an empty-bottle guarantee. We scored all eight on seven points, and the capsule finishes first at 27 of 35. We make it, so check our math.

Column order: maker and track record, price, running cost, skill and everyday practicality, proof so far, safety, wow. Prices marked "roughly" are typical retail estimates.

Reading the chart: MosquitoNoBite leads at 27 on price, ease and safety, and its weak spot is wow. Daily spray use runs about $0.75 to $2.20 a day, and it has to be reapplied every few hours, though sprays have the best proof of anything here. Wearable netting is cheap and safe, and a fashion disaster nobody will wear. Going where the mosquitoes aren't wins on wow and loses on price and practicality, and mosquito dunks only help where there's standing water to treat.

Why each one scored what it did

#1 · 27 of 35

MosquitoNoBite

Expected $49.95 for a 90-day bottle with free shipping, or $24.95 for a 30-day bottle without it. Two 90-day bottles cover a six-month season for under $100 with free shipping, about 55 cents a day. One 30-day bottle covers four people for a week, which matters because sharing is common. Nothing to charge, aim or reapply. source (source: MosquitoNoBite pricing page, opens in a new tab)
Tested since 2009, sold from 2012 until it was discontinued in 2017, used in numerous field operations, and now coming back for everyone, with user-verified reviews on the way. Intended to dramatically reduce mosquito interest when taken as directed, building over 12 to 24 hours. Backed by the empty-bottle guarantee. source (source: MosquitoNoBite home page, opens in a new tab)
The active ingredient is a compound already found in the human body, so side effects are minimal even at high doses and none are expected when taken as directed. Wow: it's a capsule.

#2 · 24 of 35

Sprays

The benchmark ingredient, DEET, was developed by the U.S. Army in 1946 and registered for public use in 1957. Sprays work, but EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)'s range for DEET is 2 to 12 hours depending on concentration, and UF/IFAS puts typical protection at one to three hours. The OFF! Deep Woods listing says up to 8 hours. source (source: EPA: DEET, opens in a new tab) source (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab) source (source: Staples: OFF! Deep Woods Insect Repellent, 6 oz, opens in a new tab)
EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab) says normal use of DEET isn't a health concern, including for children. Labels say to keep it off cuts and not to use it under clothing. source (source: EPA: DEET, opens in a new tab)
A 6 oz can of OFF! Deep Woods (25% DEET) was $7.39 at Staples, with other listings up to about $13, and for daily outdoor use a month of spray is more like three to five cans, more if it's shared, which is common. That's roughly $22 to $65 a month, or $0.75 to $2.20 a day, against about 55 cents for MNB, and both are seasonal costs. source (source: Staples: OFF! Deep Woods Insect Repellent, 6 oz, opens in a new tab)
The catch is also reapplying every few hours, and more often when you sweat, which outdoors is most of the time. UF/IFAS says sweating or swimming shortens protection. It also has a distinct smell and feel that many people dislike, which adds up when you use it daily. source (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab)

#3 · 24 of 35

Wearable netting

A mesh body suit (a jacket with a hood, plus pants) runs about $15 on Amazon, and a basic head net was $3.99 at Campmor. It's a physical barrier on whatever it covers, and almost nobody will wear one to a barbecue. It suits people who are already suited up, like anglers, hunters and gardeners. source (source: Amazon: mosquito net suit listings, opens in a new tab) source (source: Campmor: Coghlan's Mosquito Head Net, opens in a new tab)
For the rest of the body, CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) advises long sleeves and long pants. UF/IFAS reports that factory-treated clothing can cut mosquito bites by 37% to 94%, and says EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab) reviewed long-term use and found no health risks. source (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) source (source: UF/IFAS: Effectiveness, Safety, and Use of Permethrin-Treated Clothing to Prevent Mosquito Bites, opens in a new tab)
Cheap, safe, and a fashion disaster. Effectiveness drops to a 2 because a net only protects what it covers, and almost nobody will wear one.

#4 · 24 of 35

Mosquito dunks

They only work where there's standing water you can treat, and they treat larvae, not you. No standing water, nothing for them to do, and mosquitoes from a neighbor's yard are untouched. Bti has been used for more than 30 years, and CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) says it doesn't control biting female mosquitoes. source (source: CDC: Larvicides, opens in a new tab)
CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) says larvicides used by the label don't harm people, pets or the environment, and Washington State's health department calls Bti nontoxic to mammals, birds and fish. source (source: CDC: Larvicides, opens in a new tab) source (source: Washington State Department of Health: Mosquito Larvicide, Bti, opens in a new tab)
A six-pack of Summit Mosquito Dunks was $11.99 at Tractor Supply, about $2 a dunk. The listing says each treats up to 100 square feet of surface water for up to 30 days. source (source: Tractor Supply: Summit Mosquito Dunks, 6 pack, opens in a new tab)

#5 · 22 of 35

Vitamin B-12 pills

CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab)'s Yellow Book calls ingesting vitamin B ineffective, and the American Mosquito Control Association says controlled lab studies found no impact from vitamin B12. A University of Wisconsin study of vitamin B supplements also found no effect on how attractive people were to mosquitoes. source (source: CDC Yellow Book: Mosquitoes, Ticks, and Other Arthropods, opens in a new tab) source (source: PubMed: Ives and Paskewitz, Testing vitamin B as a home remedy against mosquitoes (2005), opens in a new tab)
Cheap, easy and harmless at ordinary doses, which is exactly why it's so popular. A 100-count bottle of 1,000 mcg tablets was $9.48 at Walmart. source (source: Walmart: Nature's Bounty Vitamin B12, 1000 mcg, 100 count, opens in a new tab)
Wow: none.

Photon Matrix laser

$988 for the indoor infrared version and from $1,088 for the outdoor blue version on the maker's store, as a preorder that ships within 120 days. source (source: Photon Matrix official store: products and prices, opens in a new tab)
Maker claims up to 30 mosquitoes per second. One unit covers a 90-degree fan up to 6 meters, so bigger areas need more units, and the rotating base is a $19.99 extra. It targets flying insects 2 to 20 mm at under 1 m/s. source (source: Interesting Engineering: Photon Matrix laser mosquito killer, opens in a new tab) source (source: Photon Matrix official store, opens in a new tab)
Runs on a power bank. The maker's September 2026 update says mass production begins that month, and the coverage we reviewed has no independent test results. source (source: Photon Matrix on Indiegogo: production update, September 2026, opens in a new tab)

Go where they're not

Outside the tropics, winter pushes mosquitoes into diapause, so a cold-season trip or a cold-season home works. In the tropics they're active all year. source (source: UF/IFAS: As climates change, prepare for more mosquitoes in winter, opens in a new tab)
Antarctica is the only place believed to have none, now that Iceland logged its first mosquitoes in October 2025. source (source: OPB: Iceland reports the presence of mosquitoes for the first time, opens in a new tab)
Not a realistic plan for most people: a trip costs hundreds to thousands of dollars, you still have to come home, and it only works if you can choose the season and the place. Best wow on the list, worst value.

Mosquitoes are seasonal in most places. Outside the tropics, winter pushes them into diapause, so you only pay for the months you need protection. UF/IFAS (source: UF/IFAS: As climates change, prepare for more mosquitoes in winter, opens in a new tab) A machine costs the same whether or not it's mosquito season.

At the expected prices, two 90-day bottles of MosquitoNoBite ($49.95 each, free shipping) cover a six-month season for under $100, about 55 cents a day. It takes 9 to 10 seasons of that to match the laser's sticker price and 11 to 12 to match the drone's.

The chart isn't rigged in our favor. A net suit, B-12 pills and mosquito dunks all cost less than the capsule, but a net only protects the skin it covers, B-12 doesn't work according to CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) and a University of Wisconsin study, and dunks only help where there's standing water to treat. Sprays land near the capsule at three cans a month and far above it at five, before you count the reapplying. Going where the mosquitoes aren't has no sensible season price, so it isn't charted.

Sharing is common with sprays, and a shared can empties fast. At one capsule a day, one 90-day bottle covers four people for about three weeks.

Capsule prices are expected launch prices and aren't final. Net suit: about $15 on Amazon (source: Amazon: mosquito net suit listings, opens in a new tab), where the top listings ran $14 to $33, bought once. A basic head net is $3.99 at Campmor (source: Campmor: Coghlan's Mosquito Head Net, opens in a new tab). B-12: two 100-count bottles a season at $9.48 (Walmart (source: Walmart: Nature's Bounty Vitamin B12, 1000 mcg, 100 count, opens in a new tab)), one tablet a day. Dunks: three treated spots, one dunk each a month, a six-pack at $11.99 (Tractor Supply (source: Tractor Supply: Summit Mosquito Dunks, 6 pack, opens in a new tab)). Sprays: three to five cans a month of OFF! Deep Woods (25% DEET), from $7.39 (Staples (source: Staples: OFF! Deep Woods Insect Repellent, 6 oz, opens in a new tab)) to about $13 a can. Laser: the indoor model at $988. Drone: $1,100 outright or $50 a month. Six-month season. Shipping and taxes excluded.

The case for the capsule

Lasers and drones are trying to win a fight. A capsule is trying to skip it.

Illustration of a person's silhouette with rings radiating outward and a mosquito approaching, labeled with the cues mosquitoes follow: carbon dioxide, body heat and skin odor. — Illustration, not to scale.

A laser has to spot every mosquito first. A capsule doesn't need to see anything.
The drone flies for 3 minutes, then naps for 30. An adult female mosquito lives 2 to 3 weeks, so you can do that math yourself.
Quadcopters are loud, and the coverage we read flags that for night use. A capsule stays quiet unless you rattle the bottle.
There's no tripod to level, no app to pair and no firmware to update, and no base station with 380 microphones either.
A repellent on your skin wears off in a few hours, and UF/IFAS (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab) says sweating or swimming shortens that. A capsule isn't on your skin.
A net suit only protects what it covers, if you can get anyone to put one on, and mosquito dunks only help where there's standing water to treat.
If MNB doesn't work for you, we'll refund the full purchase price, even if the bottle is completely empty.

Fair is fair

Where the others win

Sprays have the best proof. EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellents have the strongest evidence of anything on this page, and CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) recommends them. The benchmark ingredient, DEET, is the standard for a reason.
The machines win on wow, and it isn't close. A laser that shoots mosquitoes or a drone that hunts them will always out-demo a bottle.
A power bank costs less to run than a monthly bottle of anything, and a net suit costs nothing after you buy it.
If you'd rather not swallow a supplement, that's a fair reason to choose a spray, a net or a device.
If the laser's 30-per-second claim holds up outside the lab, it's remarkable. We'd like to see someone test it.

We can't promise you'll never get a mosquito bite. That would be an unreasonable claim. When used according to directions, MosquitoNoBite is intended to dramatically reduce mosquito interest, naturally. It is not intended to diagnose, prevent or treat malaria (source: CDC Travelers' Health: Malaria, opens in a new tab) or any other mosquito-borne illness. If you're traveling somewhere with mosquito-borne disease, follow CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) guidance and use an EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellent. A capsule, a laser and a drone are not substitutes for that. Talk to your doctor before taking any supplement, and before giving one to a child under 12.

Questions people ask

Mosquito FAQ

Do mosquito lasers actually work?

The maker says the Photon Matrix can hit up to 30 mosquitoes per second within about 20 feet. Those are the company's numbers. In the coverage we reviewed, no independent test results were published, so treat the claim as unproven until someone outside the company checks it. Sources: Interesting Engineering (source: Interesting Engineering: Photon Matrix laser mosquito killer, opens in a new tab) and Fox Business (source: Fox Business: Laser-wielding mosquito killer hits market, opens in a new tab).

Is there really a drone that hunts mosquitoes?

Yes, in prototype form. Tornyol's 40-gram drone finds insects with ultrasonic sonar and hits them with a propeller. Its first air-to-air kill was a moth, not a mosquito, and the company says mosquitoes are next. It flies about 3 minutes per charge. Sources: New Atlas (source: New Atlas: Tornyol drone uses sonar to hunt mosquitoes, opens in a new tab) and Ecoticias (source: Ecoticias: Tornyol's first autonomous kill was a moth, not a mosquito, opens in a new tab).

How much do a mosquito laser and a mosquito drone cost?

The Photon Matrix laser costs $988 for the indoor infrared version and from $1,088 for the outdoor blue version on the maker's store, as a preorder. The Tornyol drone is $1,100, or $50 a month on a subscription according to press coverage, and its site shows a refundable $100 deposit with US shipping targeted for 2027. MosquitoNoBite's expected pricing is $24.95 for a 30-day bottle, or $49.95 for a 90-day bottle with free shipping. That pricing isn't final. Sources: Photon Matrix store (source: Photon Matrix official store: products and prices, opens in a new tab), Tornyol (source: Tornyol (official site), opens in a new tab), New Atlas (source: New Atlas: Tornyol drone uses sonar to hunt mosquitoes, opens in a new tab).

What actually works to prevent mosquito bites?

CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) recommends EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellents with one of six active ingredients: DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone. CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab)'s Yellow Book adds that the effectiveness of repellents not registered with EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab), including some natural ones, is unknown. Skin repellents do work, but they don't last: UF/IFAS puts DEET at one to three hours of protection in typical conditions and says sweating or swimming shortens it. MosquitoNoBite takes a different route: it's a dietary supplement made from a proprietary blend of organic ingredients, intended to naturally dissuade mosquito interest, with no smell and no unwanted chemicals. Its active ingredient is a compound already found in the human body. It isn't an EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellent. Sources: CDC Travelers' Health (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab), CDC Yellow Book (source: CDC Yellow Book: Mosquitoes, Ticks, and Other Arthropods, opens in a new tab), EPA ingredient list (source: EPA: Skin-applied repellent ingredients, opens in a new tab), UF/IFAS (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab).

How long does a repellent spray last?

UF/IFAS says DEET usually provides one to three hours of protection in typical situations, and that sweating or swimming shortens it, so it has to be reapplied. EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab) puts the range at 2 to 12 hours depending on the concentration in the product. Sources: UF/IFAS (source: UF/IFAS: Use and Application of Insect Repellents, opens in a new tab), EPA (source: EPA: DEET, opens in a new tab).

Do mosquito dunks work?

Mosquito dunks are floating briquettes of Bti, a soil bacterium that's toxic to mosquito larvae. They only help where there's standing water you can treat, and CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) says Bti doesn't control biting female mosquitoes. CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) also says larvicides used according to the label don't harm people, pets or the environment. Source: CDC (source: CDC: Larvicides, opens in a new tab).

Does wearable netting work?

A net is a physical barrier on the skin it covers. CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) advises long sleeves and long pants, recommends sleeping under a mosquito net when you're outside or in a room without screens, and says permethrin-treated clothing keeps working after multiple washings. A mesh body suit or head net only protects what it covers, so it suits fishing and gardening better than a barbecue. Source: CDC Travelers' Health (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab).

Are mosquitoes around all year?

In the tropics, yes. Outside the tropics, winter pushes mosquitoes into a dormant state called diapause, which is why one way to avoid them is to travel to a place or season where they aren't active, though that's rarely cheap or practical. Antarctica is the only place believed to have none, now that Iceland logged its first mosquitoes in October 2025.

Do oral mosquito repellents, like garlic or vitamin B, work?

CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab)'s Yellow Book calls ingesting vitamin B or garlic ineffective, and the American Mosquito Control Association says controlled lab studies found no impact from garlic or vitamin B12. A University of Wisconsin study of vitamin B supplements also found no effect on how attractive people were to mosquitoes. MosquitoNoBite is a dietary supplement, not an EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellent, so where mosquito-borne disease is a real risk, follow CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) and use an EPA (source: EPA: Find the insect repellent that is right for you, opens in a new tab)-registered repellent. Where you just want fewer backyard bites, the empty-bottle guarantee lets you test MNB without risking the purchase price.

Do ultrasonic repellers and mosquito wristbands work?

CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab)'s Yellow Book says sound-emitting devices and repellent-impregnated wristbands are ineffective. Lasers and drones are a different category because they try to kill mosquitoes rather than repel them, but the lesson carries over: if there's no money-back option, ask for independent test data before you buy any gadget.

Why do mosquitoes bite some people more than others?

Mosquitoes track the carbon dioxide in your breath (from about 35 meters away), plus body heat, lactic acid and compounds from skin bacteria. The American Mosquito Control Association says differences in how attractive people are come down to body chemistry.

Do only female mosquitoes bite?

Yes. Females need blood so their eggs can mature. Males never take blood meals and feed on plant nectar, much like honeybees. Source: AMCA (source: American Mosquito Control Association: FAQs, opens in a new tab).

When are mosquitoes most active?

Many species bite most at dawn and dusk. CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) says Aedes aegypti, which spreads dengue (source: CDC Travelers' Health: Dengue, opens in a new tab), chikungunya (source: CDC Travelers' Health: Chikungunya, opens in a new tab), yellow fever (source: CDC Travelers' Health: Yellow Fever, opens in a new tab) and Zika (source: CDC: Zika Virus, Recommendations for Travelers, opens in a new tab), peaks after sunrise and at sunset, Culex peaks after sunset, and Anopheles bites in the evening and at night. CDC (source: CDC Travelers' Health: Avoid Bug Bites, opens in a new tab) also notes mosquitoes can live indoors and bite day and night.

What diseases do mosquitoes spread?

Is a mosquito laser safe for kids and pets?

The maker says the device includes human detection, background detection and short-pulse laser control to prevent unsafe firing, and that pets are treated as non-targets. Neither the coverage nor the maker's store pages we reviewed state a laser safety class or an eye-safety certification, so look for one before you buy.
