Ultrasonic Pest Repeller
Six plug-in units, three sweep modes, and a night light you can actually sleep next to.
Personal · IA-B1
The Bite Relief Heat Pen applies 45, 48 or 50 °C to a bite for three seconds and then switches itself off. Concentrated heat at the bite site is a well-established way to take the edge off itching, and doing it with a ceramic contact plate avoids another layer of cream. It charges over USB-C and runs for roughly 500 applications per charge. At $21.99 it lives in a day bag rather than a bathroom cabinet. It is for intact skin on adults and children aged three and over, never on broken skin or near the eyes.

Concentrated heat at the bite site is a well-established way to take the edge off itching. This pen puts a ceramic contact plate at 45, 48 or 50 °C for three seconds, then shuts itself off. No cream to reapply, no battery to replace — it charges over USB-C and runs for roughly 500 applications.
It feels like a hot spoon held briefly against the skin. Most adults describe it as warm rather than painful; start on the 45 °C setting.
From three years old, with an adult holding the pen. Do not use on infants.
45 °C. Move up only if the first pulse did not settle the itch — the point of three levels is that the lowest one often is enough.
It is a personal-care device for the temporary relief of itching, not a treatment for any condition. If a bite swells badly or shows signs of infection, see a doctor.
Six plug-in units, three sweep modes, and a night light you can actually sleep next to.
UV light pulls them in, a quiet fan pulls them onto the board. No zap, no tray of ash.
Twelve coils and six stands — roughly seventy hours of patio cover per box.
