I have to curtail virtually all summer activities where mosquitoes or black flies are a problem. Have a cabinet with half a dozen “sprays” that seem to work more by drowning the little critters rather than repelling them. In August, I really like to observe the meteor showers and Wendy suggested your product. Covered my face and arms with it, the rest of my body in clothing and went and sat in a field. It worked!!! I got bunches of bites on my ankles through my socks but nothing around my face or hands. Yippee! So, all in all, it’s a pretty popular product at this house. Thank you for this great option.
