The best insect repellent depends on your activity, but DEET and Picaridin are the gold-standard, EPA-approved choices for skin. For clothing and gear, an insecticide called Permethrin is the most effective choice.
DEET is a reliable and highly effective insect repellent.
To prevent dengue, use an EPA-registered insect repellent containing one of these active ingredients: DEET, Picaridin, Oil of Lemon Eucalyptus (OLE), or IR3535. Since dengue is primarily spread by day-biting Aedes mosquitoes, consistent application is crucial.
For St. Lucia, the best bug sprays contain 20% to 50% DEET or 20% Picaridin to guard against tropical mosquitoes and sandflies (no-see-ums).
Whether DEET or a DEET-free repellent is better depends entirely on your destination and personal preferences. Both are highly effective, but they serve different needs.
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.
Body lotions that effectively repel mosquitoes rely on EPA-approved active ingredients like Picaridin or IR3535, or plant-based compounds like Oil of Lemon Eucalyptus (OLE). These options moisturize the skin while actively deterring bugs, avoiding the greasy feel and harsh chemical odors of traditional sprays.
Mosquitoes rely on their sense of smell to hunt for humans (detecting carbon dioxide and body heat). You can disrupt their sensors by using the smells they hate most:
Aruba is widely considered the Caribbean island with the fewest mosquitoes. As an arid, desert-like island, it lacks the lush rainforests and standing freshwater where mosquitoes breed. Additionally, constant 15 to 20 mph trade winds make it incredibly difficult for the insects to fly or bite.
Picaridin is generally considered slightly safer and much more comfortable to use than DEET. Both are approved by the EPA and CDC for repelling mosquitoes and ticks, but Picaridin causes less skin irritation, is odorless, and does not damage plastics or synthetic gear like DEET does.
The top ten worst states for mosquitoes are:
"In India, we observe a significant surge in dengue cases during the monsoon season (June to September), primarily due to stagnant water becoming breeding grounds for mosquitoes.
While DEET is effective at small concentrations, higher concentrations offer protection for a longer period of time. For example, about 5 percent DEET protects for about 90 minutes, while about 25 percent DEET may provide about five hours of protection. The highest recommended concentration is 30 percent.
The strongest and only CDC-recommended plant-based bug repellent is Oil of Lemon Eucalyptus (OLE). It provides up to 6 hours of mosquito protection, rivaling synthetic chemicals like DEET. For broad protection without OLE, cedarwood-based sprays are highly effective.
Yes, Vicks VapoRub can temporarily deter mosquitoes because of its strong scent, but it is not a reliable or recommended mosquito repellent.
The country with the worst mosquito problem depends on how you measure it: sheer insect population versus the severity of the diseases they spread.
Iceland is the only country in the world that is completely free of mosquitoes.
Where do the wealthy live in the Caribbean? They are often found in exclusive destinations like St. Barts, Turks and Caicos, Anguilla, and the British Virgin Islands, where privacy and luxury are prioritized.
When planning a Caribbean getaway, you should avoid or heavily research destinations with active U.S. State Department travel advisories due to high crime, civil unrest, or limited medical infrastructure. Always check real-time updates using the U.S. Department of State Travel Advisories before booking.
Natural Mosquito Predators
A mosquito repellent deodorant combines sweat protection with bug-deterring ingredients. These hybrid products target mosquitoes' attraction to the carbon dioxide and lactic acid in human sweat by masking your scent.
Iceland is widely known as the only country in the world completely free of mosquitoes. While some isolated locations and freezing environments have few mosquitoes, Iceland is the only sovereign nation with no native mosquito populations at all.
Mosquitoes are repelled by perfumes that contain strong herbal or citrus notes like lemongrass, citronella, lavender, peppermint, and eucalyptus. Interestingly, studies have also found that certain fruity-floral fragrances, like the popular Victoria's Secret Bombshell, temporarily repel mosquitoes.
Avoid being outside during peak mosquito hours – Mosquitoes are most active at dawn and dusk, though specific hours vary by species. Minimize your risk of being bitten by staying indoors or wearing long sleeves and pants if you're outside during these times.
That is foolishness. Even if we kill one mosquito, we are responsible. It is not man-made law, that “If you kill a human being, then you are punished, and if you kill another animal, you are not punished.” This is man-made law according to our convenience.
