My friends were discussing how to deal with insects bites from mosquitoes and sandflies. One idea is to apply heat web page like using the lighted end of a cigeratte or using a heated spoon. I don't smoke but have my surefire 9P/P90. Tried it and it works, relieving itch I mean. My friend do it all the time with an M2/P61. It should be hot enough. Not with the L4 though.
