That exact timeframe in '18 there were plenty of non-biting small insects at night, which was during one of the bug flow periods. If you're bunking out with a head lamp on for awhile you will attract larger flying insects like moths, which in turn will have bats up close and personal. Take a blacklight with you to find scorpions if you have the stomach for it. Might be better to be careful and not to know. Have fun.
I don't get mad, I get even.
