Follow Adam as he takes you scorpion hunting at night with a blacklight. Here, he notes how scorpions are "thigmotropic" and feel uncomfortable when they don't have pressure on two sides of their body.
Do you have anything to flush him with? Oh my gosh, did you see the bug? Those things are so fast. Scorpions. They'll only come out the open like this at night. They are thigmotropic, which means that they like to feel pressure on at least two sides of their body. When we scratch the wall...He's struck...and they run to a crack.
