ThermalDots - Temperature Monitoring Stickers

At ThermaloStrike, we leave nothing to chance when it comes to bed bug heat treatment.  Our ThermalDot stickers have become the industry standard for checking temperatures inside of home dryers, validating the effectiveness of a home treatment, and essential when dealing with books and files.

ThermalDots change color from grey to black at 120°F. The sticker will continue to stay black as evidence even after the items have cooled.


Where To Use ThermalDots

Bed bugs die when exposed to temperatures above 113°F for several hours, however, it is widely accepted that 120°F / 49C° is the lethal temperature where all stages of life (adult, nymph, and eggs) are guaranteed to be exterminated within seconds.  It is not always easy to check the temperature inside items such as books or papers.

ThermalDots are designed to change color from grey to black at 120°F. The sticker will continue to stay black as evidence even after the items have cooled.

Provided as a pack of 21 temperature sensitive stickers, this product works with all heater manufactures.

Books & Papers

Books can take extra time to reach temperature. Place the sticker in the middle of the book.

Heat Treating Difficult Items

For hard to treat items like shoes and boots, place Thermal Dots in the toe area.


Checking Dryer Temperature

Stickers may be placed in pockets of jackets or inside sleeping bags, blankets, etc.

Professional Heat Treatments

Place stickers around the room. Including drawers, closets, bed frames, carpets, etc.
