The most effective bug bite relief we've found for serious anglers. Heat It Classic is a small, smartphone-powered medical device that uses concentrated heat to stop the itch and pain of insect bites within seconds. No chemicals, no batteries, no creams — just plug it into your phone, place it on the bite, and the itch is gone. Small enough to live on your keychain or in a sling pack pocket, this thing has become an on-stream essential for guides and anglers fighting summer bugs.
The science is straightforward. Heat It applies a brief burst of concentrated heat (around 124°F) to the bite for 4 to 9 seconds, depending on the setting in the free Heat It app. The heat denatures the proteins in mosquito and horsefly saliva that cause itching, and it interrupts the nerve signals that tell your brain to scratch. A 2023 scientific study with over 1,700 participants and 12,000 treatments confirmed what anyone who's used one already knows — it works fast and it works on real bug bites.
For fly anglers, this matters. The Lower Gunnison in summer can be a gnat factory, the Uncompahgre tailwater pulls horseflies, and any high country trip means mosquitoes. Heat It fits in a wader pocket, runs off your phone (no batteries to replace, ever), and treats bites on the water within seconds of getting bitten. It's effective on bites from mosquitoes, horseflies, gnats, bees, and wasps. App offers settings for adults, sensitive skin, and children ages 3 and up.
USB-C — for most current Android phones and iPhone 15 and newer.
Lightning — for iPhone 6s through iPhone 14.
Not sure which you need? Look at the charging cable that came with your phone. If the small end that plugs into your phone is oval and reversible, you need USB-C. If it's a flat rectangle, you need Lightning.
