I've also had great success with picaridin! Though I used the dry powder spray.

It's been in my rotation for a year or two now, works great.

Except for whatever reason, last weekend, it seemed to worked a little, but largely not. We got absolutely destroyed. We planned 3 days 2 nights, but we cut out the second day.

I've seen thick clouds of mosquitoes before, this wasn't that. But there were plenty of them, and no matter how often we reapplied, we got bit.

Only in the direct sun were we safe. Or if the wind picked up for a bit.

I'm not against picaridin, I'll try it again. But I wished I had some deet with me to do an A/B comparison.
