The Basics:

Although they are relatively hardy, House Geckos
can be nervous and jumpy. A light brown lizard with attractive markings, the House Gecko reaches an adult length of 4-5 inches, though some can be slightly smaller or
larger. Typically, they reach their adult size within 18 months. Although some House Geckos may live up to 10 years, a lifespan half that length is not unusual. Captive bred
House Geckos will have a longer lifespan. Nocturnal animals, House Geckos are not active during the day. Like the Day Gecko, this lizard can walk up smooth vertical surfaces and make a variety of vocalizations.

Enclosure:
Vertical Space With Lots Of Plants :

House Geckos like to climb, so provide them with an enclosure that offers ample up-and-down space, and plenty of climbing branches. It's also a good idea to attach cork bark to an inside wall to provide a climbing area. House Geckos are ideal pets for elaborately planted terrariums, planted with nontoxic plants like Pothos. Shy animals, they do best when secure hiding places are provided in their enclosures. House Geckos are rarely territorial or aggressive, so they can be housed in pairs or small groups. However, do not place more than one male in the same enclosure since they will fight. A 20-gallon aquarium or larger, with a secure screen top, should be used for a pair of House Geckos. Larger tanks should be used for larger groups.

Substrate:
Maintain Thick Bedding:

A House Gecko's enclosure should have 2-3 inches of
reptile bark, coconut fiber or mulch bedding. This will help maintain humidity levels and support live plants. This bedding should be cleaned daily, and replaced monthly. If a
House Gecko shows a tendency to eat bedding, the substrate should be switched to something edible, paper or indoor/outdoor carpet. Sand, aquarium gravel and any bedding prone to mold should be avoided.

Temperature:
Moderate Temperatures:

House Geckos must be provided with a thermal gradient, ranging from 75º to 88º Fahrenheit during the day. This will allow them to regulate their body temperatures by moving in the enclosure. Nighttime temperatures should be lowered to 70º. Temperatures in the enclosure should never be allowed to drop below 65º. The House Gecko keeper can maintain proper temperatures using an under tank heater and a lamp. A thermometer should be positioned in the warmer and cooler areas to monitor temperatures. Important - see the Note About Day/Night Light Cycles and Heating below.

Note About Day/Night Light Cycles and Heating:

All reptiles, including this pet, must have distinct day and night periods in their enclosure to maintain their biological rhythms. (See the lighting entry above for the specific length of this animal’s day/night cycle.) The day period must be light; and night must be dark. A timer should be used to set day/night periods. If a heat source is required to maintain correct nighttime temperatures, use heat mats or strips mounted below or on the side of the tank, infrared heat lamps, ceramic heat emitters, or a combination of these products. This will allow the enclosure to be heated while remaining dark. Follow directions carefully with all products. If ceramic heat emitters are used always choose fixtures with porcelain or ceramic sockets and to protect against fires do not place them by dry wood or flammable fabrics. Ceramic heat emitters must be kept out of the reach of children and all pets, including dogs and cats.

Humidity:
Relatively High:

It's important to maintain relatively high humidity levels in a
House Gecko's enclosure. The humidity level should be kept at 65-75%. This can be accomplished by misting the enclosure once or twice a day with chlorine-free water, and using live plants like Pothos. A hygrometer should be used to measure humidity levels. However, care should be taken not to create an enclosure environment that is too humid, since this will promote fungal infections and jeopardize the health of the gecko. Signs that an enclosure is too humid include: substrate that appears soaked or saturated rather than just damp, and moisture build up on the sides of the tank.

The following is a possible supplementing schedule for this reptile. Feeder insects should be dusted with a supplement every other or feeding or a little less often. However, this is only a general suggestion -- the best specific schedule may vary depending on the supplement products used and other factors. Please consult product package directions, outside literature and a veterinarian to determine the optimal supplementing program.
