Zap away the itch from bug bites

Posted: Updated:

(WILX)  When bug sprays don't work, and you're left with the itchy red welts so common this time of year, you can reach for anti-itch cream, or now you can reach the Therapik.

Its makers claim the device ends the pain and itch in 30 seconds by using heat from a tiny light bulb.

"It may be destroying some of the proteins that are injected by the female mosquito, and those are the things that elicit the immune response, that you get itching and that sort of thing with it," says Dr. Michael Kaufman, an associate professor of entomology at Michigan State University.

The device is also supposed to work on bee and wasp stings and even jelly fish stings. If it doesn't work with one 30 second treatment, you can use it multiple times until you notice some relief. There are no warnings against use on children, but that bulb is warm, and you have to hold still to use it.

 The device recently got FDA approval and is being sold at Wal-mart and online at retailers like It sells for around $12.
