Top 7 Best Spray for Sand Fleas in 2024

1. REPEL Lemon-Eucalyptus Spray

REPEL Lemon-Eucalyptus Spray is your go-to solution for warding off those pesky sand fleas. What sets this repellent apart is its reliance on the power of lemon eucalyptus oil, making it a safer yet highly effective alternative to DEET-based repellents.

According to the CDC, both DEET and lemon-eucalyptus oil sprays have shown promise in combating insects responsible for transmitting diseases like Zika and malaria, particularly in regions such as Africa. However, the key is to ensure that your chosen repellent offers long-lasting protection.

When you apply REPEL Lemon-Eucalyptus, you can bid farewell to ticks attaching themselves to your skin, as they simply cannot cling on. Additionally, any surface treated with this spray becomes a no-go zone for these unwanted critters. As a bonus, it’s also safe for your pets, though using a tick shampoo for them is advisable.

What truly sets this sand flea spray apart is its natural composition. Enriched with a blend of essential oils, it effectively eliminates both sand fleas and mosquitoes without resorting to harsh chemicals. This makes it an ideal choice for those with sensitive skin, like myself. I used to suffer from unpleasant rashes after using chemical-laden bug repellents, but REPEL Lemon-Eucalyptus has been a game-changer for me.

The Good:

  • The DEET-free formula provides up to 6 hours of protection.
  • Non-sticky and non-greasy lemon eucalyptus formulation.
  • Effectively repels insects such as sand fleas and mosquitoes.
  • Boasts a refreshing scent.

The Bad:

  • None to report.

Say goodbye to sand flea woes with REPEL Lemon-Eucalyptus Spray – your natural, skin-friendly defense against these tiny terrors.

Choosing the Right Sand Flea Repellent: Key Considerations

When it comes to selecting a sand flea repellent, you’ll encounter various options like lotions and sprays. Your decision largely hinges on your preferred active ingredients, such as DEET, IR3535, and essential oils. Let’s explore these choices and the factors to consider.

1. DEET: The Ultimate Sand Flea Defense

If you’re seeking the most potent bug repellent, DEET should be your top pick. Whether in lotion or spray form, DEET stands as one of the most effective defenses against sand flies.

Rest assured, it’s extensively researched and EPA-approved for safe use when used as directed. Embrace DEET, and bid farewell to those relentless sand fleas!

2. IR3535: The Versatile Sand Flea Fighter

Meet IR3535, a versatile superhero among active ingredients. It not only combats sand fleas but also tackles body lice, deer ticks, and mosquitoes – biting flies

While not as powerful as DEET, IR3535 is both EPA and EWG-approved for safety. Be mindful not to overuse it due to its shorter re-application intervals, especially when combined with sunscreens.

3. Plant Oils: Nature’s Bug-Repellent Arsenal

For a natural approach to sand flea control, consider repellents infused with essential oils like lemon eucalyptus, lemongrass, and Citronella.

These oils effectively ward off sand flies and other biting insects while posing minimal risk to humans and pets, according to the EPA. Harness the power of nature to keep sand fleas at bay!

4. Marmite: The Unconventional Hero

In a surprising twist, New Zealanders have found an unconventional ally against sand fleas: Marmite. Rich in vitamin B, Marmite can help control sand fleas.

Yes, you read it right! If you can stomach the taste, consuming some Marmite might provide a unique way to fend off sand flea bites without applying lotions or sprays. It’s a tasty addition to your bug-repelling arsenal! 

2. Avon Skin So Soft Bug Guard Plus: On-the-Go Protection Repellent With SPF

Avon’s SPF 30 formulation harnesses the power of IR3535, aloe, vitamin E, and SPF 30 to create a highly effective shield against sand fleas and other insects.

While Avon recommends re-applying the SPF 30 every 80 minutes, we understand that it might not always be practical, especially on long outdoor excursions. If you’re in search of the ultimate sand flea repellent, look no further!

Our yard is often besieged by gnats, sand fleas, and mosquitoes, which can pose serious risks in the spring. Wondering if sand flea sprays actually work? Sand fleas thrive in hot, humid climates like Florida and the Caribbean, and Avon SPF 30 offers excellent protection against their bites. It’s also fantastic for warding off regular flea bites.

I’ve been a loyal user of this product for years, and in my opinion, it’s the best bug spray on the market. It not only provides exceptional bug protection, especially during the summer, but also offers reliable sun protection. Gone are the days when I’d get devoured by bugs while camping or fishing. Plus, its sunscreen is a game-changer for fair-skinned individuals like myself.

The Good:

  • Non-staining and non-greasy
  • PABA and DEET-free
  • Provides sunburn protection
  • Water-resistant

The Bad:
