6 Best Natural Bug Spray Sunscreens That Last Through Sweat and Rain

You’re an hour into a humid climb in the Appalachians, the air thick with the drone of mosquitoes and the sun beating down through the canopy. You stop to reapply sunscreen, then realize you forgot the bug spray in the car. Or maybe you have both, and the sticky, greasy combination is making you miserable.

Simplify Your Pack with Dual-Action Protection

Every ounce matters when it’s on your back. Carrying two separate bottles for sun and bug protection is a classic packing dilemma—it’s more weight, more space, and more hassle on the trail. Combining these into a single, effective product simplifies your ditty bag and your entire routine.

This isn’t just for the ultralight thru-hiker, either. For a day hiker or a family heading to the lake, one less thing to forget is a huge win. The key tradeoff, of course, is specialization. A dedicated bug repellent might be stronger, and a standalone sunscreen might feel better on your skin. But for most adventures, from a paddle down a lazy river to a weekend backpacking trip, the convenience and weight savings of a two-in-one formula are hard to beat.

Badger Anti-Bug SPF 34 for Sensitive Skin Use

Picture a buggy, sun-drenched day at a mountain lake with the whole family. If you or your kids have sensitive skin, slathering on chemical-laden products can be a non-starter. This is where a mineral-based combo product really shines. Badger uses non-nano zinc oxide for sun protection, which sits on top of the skin rather than being absorbed.

The bug-repelling action comes from a blend of essential oils like citronella, cedar, and lemongrass. This makes it a DEET-free and chemical-filter-free option that many people find gentler on their skin. The main consideration here is reapplication. Essential oil-based repellents typically need to be reapplied more frequently than their chemical counterparts, especially after a swim or a good sweat session. For those prioritizing gentle, natural ingredients, this is a top-tier choice.

Avon Bug Guard Plus: Proven Picaridin Defense

When you’re heading into seriously buggy territory—think the Boundary Waters in June or the Everglades in the shoulder season—you need reliable protection. While not strictly "natural" in the essential oil sense, Picaridin is a fantastic alternative to DEET. It’s a synthetic compound inspired by a natural one found in pepper plants and is known to be effective without being as harsh on gear or skin.

Avon’s Bug Guard line pairs this proven repellent with solid sun protection. This is a workhorse formula for anyone who wants dependable, long-lasting defense without the oily feel and potent smell of DEET. It’s a smart choice for long days of hiking, fishing, or paddling where you can’t be stopping every hour to reapply. It strikes a great balance between performance and user experience.

Bullfrog Mosquito Coast: High SPF Water-Resistance

Some adventures are just plain wet. Whether you’re kayaking coastal mangroves, fly fishing a rushing river, or just hiking through a classic summer downpour, your protection needs to stick. Bullfrog built its reputation on water resistance, and the Mosquito Coast formula is designed for these exact scenarios.

This product typically features higher SPF values and a formula engineered to stay put through sweat and water. This is crucial when sun reflection off the water doubles your exposure. The bug defense is robust, designed to keep biting insects at bay even in damp, marshy environments. The tradeoff for this level of durability can sometimes be a heavier feel on the skin, but when conditions demand it, sacrificing a bit of comfort for lasting protection is a smart move.

Greenerways Organic for Chemical-Free Hiking

For some adventurers, the ingredient list is the most important feature. If you’re committed to an organic, chemical-free approach, a product like Greenerways is built for you. These formulas rely entirely on a potent blend of USDA Certified Organic essential oils, such as citronella and lemongrass, to repel insects, paired with a mineral sunscreen.

This is the go-to for a short day hike in a place with low-to-moderate bug pressure or for anyone with extreme chemical sensitivities. The primary tradeoff is performance duration. You’ll need to be diligent about reapplying, as sweat and rain will wash it away faster than other options. Think of it as a great tool for the right job, not an all-purpose shield for the deepest, buggiest woods.

Repel Lemon Eucalyptus: CDC-Recommended Ingredient

What if you want a plant-based repellent that packs a serious punch? Look for formulas centered on Oil of Lemon Eucalyptus (OLE). This is a refined oil, not the essential oil, and it’s the only plant-based ingredient recommended by the CDC as an effective alternative to DEET for mosquito protection.

Repel’s combination of this powerful, plant-derived repellent with sunscreen gives you the best of both worlds: natural origins and scientifically-backed performance. It’s a significant step up in effectiveness from classic citronella blends. The smell is distinct and strong—some find it pleasant, others don’t. For anyone wary of DEET but demanding high performance for buggy backcountry trips, this is a fantastic option to have in your pack.

Babyganics Mineral SPF 50 for Young Adventurers

Taking little ones on the trail requires a whole different level of care. Their skin is more sensitive, and you want to be incredibly mindful of what you’re putting on it. Babyganics focuses on this niche, offering mineral-based sunscreens (zinc oxide and titanium dioxide) that are gentle and effective.

Their bug-repelling formulas add a blend of gentle essential oils to the mix, creating a two-in-one product designed specifically for babies and kids. The high SPF 50 rating provides excellent sun protection for a long day outdoors. Always check with your pediatrician before using any new product on an infant, but for toddlers and young kids, this is a purpose-built solution that gives parents peace of mind.

Choosing Your Shield: Picaridin vs. Essential Oils

Ultimately, your choice comes down to your personal priorities and the demands of your trip. There is no single "best" option, only the best option for a specific environment and user. Think of it as a spectrum of performance versus ingredients.

• Picaridin & Oil of Lemon Eucalyptus (OLE): Choose these for maximum protection and duration.

  • Best For: Areas with high bug density (e.g., Midwest forests, southern swamps), regions with insect-borne illnesses, or multi-day trips where reapplication is a hassle.
  • Tradeoff: While generally considered safe and effective, they are still potent chemical compounds.

• Essential Oil Blends (Citronella, Lemongrass, Cedarwood): Choose these for sensitive skin or if you prioritize all-natural, organic ingredients.

  • Best For: Casual day hikes, backyard use, people with skin sensitivities, or areas with low bug pressure.
  • Tradeoff: You must be diligent about frequent reapplication, as their effectiveness fades much more quickly, especially with sweat or rain.

Your decision hinges on this key question: Are you optimizing for ingredient purity or for repellent performance and longevity? Answering that will point you directly to the right product for your pack.

Don’t let the fear of sun or bugs keep you inside. The right dual-action spray simplifies your gear, lightens your load, and keeps you comfortable. Pick the shield that fits your adventure and your philosophy, throw it in your pack, and get out there. The trail is waiting.
