Mosquito pain receptors found to be less sensitive during extreme heat, which could nullify some natural bug sprays

Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study. Researchers found that a pain receptor called TRPA1 becomes less sensitive in mosquitoes when exposed to heat, meaning that the chemical cues that typically trigger insect avoidance behaviors are prevented from activating as strongly.
