Yeah 100% deet works but you still get bites here it seems they became immune. South dakota is like nebraska a few chiggars on hottest days but here think billions of seed ticks ,chiggars ,buffalo gnats, cottonmouth,copperhead,timber rattlers,gators. The north gets cold enough these do not exist in the densities comparable. I can walk out my door and if I step one foot outside where I sprayed i'll be ate up in seconds! I had to come home sometimes from work because I had literally 1000s of seed ticks crawling on me. I have worked in Nebraska ,Indiana,Michigan,Missouri,Texas,and here the first four states mentioned were a breeze the last two are virtually like bathing in stinging nettles not comparable lmao.
