To protect yourself from itchy bites and even infections, you'll want to snag one of the best sand flea repellant. Below, I’ve rounded up highly rated bug repellents, ranging from all natural picks to the strongest stuff on the market. Whether you call them sand flies, no-see-ums, or beach fleas, there’s surely a repellent below to keep you as bite-free as possible.
Repellents abounds, so let this be your guide to effective ingredients that should help you avoid the dreaded sand flea bites.
- Deet: If you’re looking for the most powerful bug repellant available, go with a DEET-based spray. While it’s potent and far from natural, DEET is considered an effective bug repellant for sand flies. Further, DEET has been studied for decades and the Environmental Protection Agency (EPA) says it poses no health risks.
- IR3535: This is an active ingredient that can also be effective against biting flies, (like sand fleas) plus mosquitoes, deer ticks, and body lice. IR3535 is deemed safe by both the Environmental Working Group (EWG) and the EPA. However, it’s generally considered less effective than DEET, and like with all synthetic bug repellants, it’s also important not to over-apply IR3535 — which can be tricky, since it’s often combined with sunscreens that need reapplied every two hours.
- Plant Oils: For a more natural way to repel sand fleas, bug sprays infused with plant oils might be your best bet. Citronella is a popular sand flea repellant, and lemongrass naturally repels sand fleas as well. Oil of lemon eucalyptus is commonly used against sand fleas and other biting bugs also. While the EPA hasn’t evaluated essential oils for effectiveness against bugs, it has evaluated them for safety, concluding that essential oils pose minimal risk to human health.
- Marmite: Admittedly, this may sound a bit wacky, but New Zealanders, who are no strangers to sand fleas, say it just might help you avoid sand flea bites. Evidently Marmite is high in vitamin B, which helps to keep sand fleas at bay. If you can stand the taste, marmite could be a way to avoid fleas without having to spray anything on your skin.
With all that in mind, below you'll find all the best sand flea repellents whether you are looking for the most powerful or the most natural.
