I would use it,if there isn't any bugs great but if you get bite up its miserable.I used the stuff with the sunscreen and bug repellant. My daughter used nothing and neither one of us had a problem. I still felt better( protected )for the just in case theory.We just returned the 5th and also the only bug we saw was a few lovebugs,until on the drive home and our windsheild was plastered with the ugly critters.We was washed our car when we stopped for gas.Susan
