I live in the deep south and mosquitoes are a year round problem. This has always been a problem for my because if one of those nasty little bugs bite me I have a whelp the size of a golf ball. Off Deep Woods Insect Repellent is a product that helps me deal with my itchy problem. Off Deep Woods offers long lasting protection and lives up to the promise. They also claim to repel ticks, biting flies, gnats and chiggers. I have fortunately not had the chance to put that claim to the test. Off Deep Woods Insect Repellent contains 25% DEET which is the active ingredient that makes this product work. The smell is not pleasant and the spray is greasy on you skin but the mosquitoes will not bit. Another problem is if get Off Deep Woods in your eyes, either by misdirected spray or rubbing your eyes with spray covered hands, you will have an eye that will painfully burn for a long time. All in all I still use this product very happily.
