Nothing ruins a hike faster than swarms of mosquitoes—or turns a backyard BBQ into a scratching frenzy. But with so many bug sprays (DEET, picaridin, “natural” options), how do you choose the best bug sprays in 2025?
Our team spent weeks researching top-rated insect repellents, analyzing CDC/EPA safety standards and expert recommendations from leading entomologists. We focused on real-world performance factors like greasiness, scent, and ease of use—not just marketing claims.
