How about "hot and bug-free" then? Most of the whiny little biters go away once the daytime temps are above 100 degrees and only the ants, scorpions, centipedes and tarantulas are around; and most of them at night. Ants are the daytime summer bugs "big ones, small ones, some as big as yer 'ead".

This is one of the reasons I don't use a tarp that much in the desert and when I do, it is mainly for shade; the creepy crawlies like shade as much as I do.
