A company called MorePower2U is marketing a new device called "Therapik", claming to provide temporary relief from bug bite irritation by the use of heat.

While this concept is not new, (see our write up on Mosquito Mouse), it's the first such device I've seen marketed in the USA.

It works on the notion that insect venom is sensitive to heat, and by applying heat, neutralizes its ability to bother you.
