Exo Terra Heat Mat, Self Regulating 4W, 10cm x 18cm Safety Mat

Exo Terra 4w self regulating heat mat provides an excellent source of heat for all your critters. It is self adhesive. Simply attach externally to any side of your pet’s enclosure (never to the bottom of the enclosure) to create a heat gradient that your critter can use to regulate its body temperature. Do not place the heat mat inside of the enclosure, nor at the base of the enclosure, as heat will rise and burrowing critters will not have a place to cool down. Recommended for use with a thermostat. The Exo Terra self regulating heat mat is designed to not exceed a certain temperature thus reducing the chance of it overheating. It can be used without a thermostat though a thermostat is recommended for fine tuning the temperature. 4 Watts is the size you would need for a small enclosure, for example for a mantis or jumping spider, approx 15 x 20cm or smaller.
