10 Best Fly Repellents 2026 in the United States

The Sawyer Products SP874 Picaridin Insect Repellent Spray is a strong contender in the fly-repellent category. The active ingredient, 20% Picaridin, is highly effective at keeping flies at bay for up to 8 hours, making it suitable for extended outdoor activities like camping, hiking, and backyard gatherings. Additionally, it offers up to 12 hours of protection against mosquitoes and ticks, which is impressive for an insect repellent.

One of its major strengths is that it's fragrance-free, non-greasy, and dries quickly, ensuring a comfortable experience without causing damage to clothing or gear. This is a significant advantage for people who are sensitive to scents or don't want their outdoor equipment affected. The spray is also safe for use on the entire family, which adds to its versatility.

While it is effective and user-friendly, the product's environmental impact isn't highlighted, which might be a concern for eco-conscious users. Some users may find the need for reapplication after 8 hours for fly protection to be a slight inconvenience. The Sawyer Products SP874 is an excellent choice for those seeking reliable, long-lasting protection from various insects during outdoor activities.

The Absorbine UltraShield EX 32oz Sprayer Insecticide is a robust fly-repellent suitable for use on horses, dogs, and premises. One of its main strengths is its ability to kill and repel over 70 species of pests, including flies, mosquitoes, ticks, and fleas. The formulation is water-based and ready-to-use, eliminating the need for mixing, which can be a real time-saver.

Its UltraBond Technology provides weatherproof protection for up to 17 days, making it highly durable. Additionally, the product includes sunscreens and coat conditioners, which is an added benefit when used on animals exposed to the sun. Its made-in-the-USA tag assures a level of quality and compliance with safety standards.

While it offers extended protection, the scent might be a point of contention for some, as insecticides often have strong odors. Users looking for a strong, long-lasting insecticide with added protection features for their animals and premises may find this product meets their needs well.

Grand Tongo DEET-Free Insect Repellent uses 20% Picaridin, a gentle alternative to DEET, making it a good choice for those with sensitive skin or concerns about harsh chemicals. It offers strong protection against mosquitoes and ticks for up to 12 hours and defends against other biting insects like flies and gnats for about 8 hours, which is quite impressive for outdoor use. The aerosol spray is lightweight, quick-drying, and non-staining, so it feels comfortable on the skin and won’t leave marks on clothing.

Its citrus and sandalwood scent is refreshing and fades quickly, avoiding the typical strong chemical smell found in many repellents. Since it’s water-based and lacks DEET, it tends to be safer for the environment and more skin-friendly, though users should still apply it as directed. One downside is that aerosol sprays can be less ideal for windy conditions or indoor use compared to lotions or wipes.

While Picaridin is effective, some users might find DEET-based repellents slightly stronger against a wider range of insects. This product suits those who want reliable, all-day protection without DEET’s harshness, making it a solid pick for everyday outdoor activities and travel.
