Thank you! I'm using Picksan, which uses the same active ingredient as (p)icaridin, and it did seem to work. I was just spooked a few days ago when a mosquito sat on me while I was wearing the stuff. It didn't bite though; and maybe I had forgotten a spot, and I'm pretty sure I didn't shake before using it like it says on the bottle. I'll definitely try the heat thing. I have tried After Bite, and it didn't seem to do much. I do have a bottle of ammonia in the house; maybe a stronger solution works better.
