Overview of Repel 100 Insect Repellent (Pump Spray, 4 oz)
If you’re heading into mosquito-heavy terrain or prepping for survival situations, Repel 100 Insect Repellent is one of the top-tier bug sprays on the market. With 98.11% DEET, this powerful formula is designed to offer up to 10 hours of protection against mosquitoes, ticks, gnats, biting flies, chiggers, and fleas. It’s especially effective in extreme environments where insect-borne diseases like Zika, West Nile, Dengue, and Lyme disease are a real concern.

✅ Compact and Portable (4 oz Pump Spray)
The 4 oz bottle is TSA-compliant and lightweight, fitting easily into backpacks, emergency kits, or glove compartments. The pump spray offers better control than aerosols, reducing waste and preventing over-application.
