Flip the switch; turn off itching

A 20- to 30-second application of heat will deactivate a mosquito bite.

If stings and bites bug you this summer, there’s a new way to alleviate the itch without chemicals.

Therapik is a small, portable hand-held device confirmed by the FDA to deliver bug bite relief from mosquitoes, bees, wasps, hornets, black flies, ants, fleas, ticks, chiggers and even jellyfish and stinging nettle.

Therapik’s design is based on the principle that most insect venom is thermolabile, or sensitive to heat. The Therapik delivers heat in the precise temperature range necessary to deactivate the venom from more than 20,000 different species of insects and sea life.

As the heat neutralizes the venom and increases blood flow to the affected area, swelling, redness, pain and itching are reduced. Therapik can be reapplied as often as necessary, on adults and children.

The manufacturer says a 20- to 30-second application will usually stop the itch and pain permanently. Not always, our test subjects found. But it’s nice to know that more applications as needed are not dangerous. And the product worked eventually.

As with many non-traditional treatments, users need to ponder the extra time chemical-free therapy involves. Treating a dozen or more bites is certainly more time consuming than dabbing the bites with antihistamine cream.

At $13 plus a set of batteries, the Therapik would likely pay for itself over years of use compared to chemical alternatives. For more information, visit
