One Spray. Covered All Day.
Most natural sprays wear off in about an hour, so you're either reapplying constantly or getting caught unprotected. That's not really being in control — that's hoping.
GuardEX is EPA-registered and lasts a full 8 hours on one application. Spray it once in the morning and you're covered through the hike, the yard work, and the walk with the dog — no reapplying, no guessing.
