Yesterday I bought the one that has +15 and kills ticks as well. I sprayed the horses with it this morning and the wind changed suddenly so a fine mist got on my hand.......within minutes I noticed a small section near my thumb was getting a little puffy.......then a little more puffy........so when I came inside I washed it for like, 10 minutes and it looks better, although it's still just a tad puffy. It's not painful, it's almost back to normal but it's still not right. And since washing it the puffiness hasn't gotten any worse.
Sooooooo I'm thinkin if this stuff works for the horses I just need to wear gloves or find something else. We were using Tri-Tec but that isn't working as well this year.
