Food & Water: Their main diet will consist of insects . Feed them a varying diet of crickets, mealworms, locusts, waxworms and spiders. If your Asiatic House Gecko is large enough, baby mice can also be offered sparingly. Make sure to dust the food items with a calcium and multi-vitamin supplement three or four times a week.
The Geckos will lick water that collects on the glass and items in the habitat. Some Asiatic House Geckos tend to lick water from a shallow dish as well.
Lighting, Temperature & Humidity: Keep the daytime temperature in the habitat from 73°F to 86°F. At night, drop this range down to 68°F to 77°F. Humidity levels should remain constant around 80%. Use full spectrum UVB lighting along with a heat source; like a ceramic heat emitter working with a pulse proportional thermostat.
Housing: A tall habitat is required for Asiatic House Geckos, as they like to climb. The overall habitat does not need to be very large however, with a minimum of 12" x 12" by 16" being sufficient. The bigger the better though. Fill the habitat with branches and plants. Asiatic House Geckos will lay their eggs on the branches and other items, so make sure they are easy to remove and transfer them to an incubator. Use a Orchid bark or coir (coconut husk) or similar as a substrate.
