Eastside mosquitoes are as ruthless as they make them, so come prepared. This Picaridin insect repellent is similar to DEET yet is safer on gear and equipment. This topical repellent works for eight hours against mosquitos, ticks, biting flies, gnats, chiggers, and fleas. As a bonus, it is more effective than DEET at repelling biting flies. 

It will not harm gear or equipment!
