The Exo Terra Forest Bark is a 100% natural, biodegradable reptile substrate made from sustainable wood bark. Forest Bark is the ideal decorative substrate for humidity-loving reptiles, amphibians and invertebrates from tropical and forest environments. Its hygroscopic properties regulate the terrarium’s humidity in a natural way by absorbing and slowly releasing moisture. The unique size and shape of the bark particles stimulate natural digging and burrowing behavior, and discourage crickets to hide in the substrate. The fir bark is extensively tumbled to smoothen the bark pieces and remove dust, than heat-treated to reduce bacterial
Exo Terra substrates are all dust-free and heat-treated at our state-of-the-art European production facility.

Care & Use
Spread a 1-2” layer (3-5 cm) of the bark on the terrarium floor. Water or mist the substrate according to the humidity level required. Use an Exo Terra Hygrometer to monitor the level. To increase air humidity in well-ventilated terrariums or those with very high humidity requirements, place an Exo Terra terrarium substrate heater underneath the terrarium. The small chip-size of the bark increases heat conductivity even when left dry. Spot clean the bedding on a daily basis, rinse the substrate in hot water for intermediate cleaning, and completely replace with new bedding every 8 weeks or when necessary.
