Can you provide a tall tank with climbable furnishing for a house gecko?
Can you maintain a daytime temperature gradient of 75 to 90 F with a nighttime low of 65 to 75 F?
Can you provide a UVA/UVB light bulb?
Can you maintain a humidity level of 60 to 75 percent in gecko's enclosure?
Can you provide a variety of small prey items for a gecko daily?
Do you have an exotic animal veterinarian who specializes in reptiles?
A 20-gallon terrarium is sufficient for a pair of common house geckos but bigger is better when it comes to their housing. Keep in mind that house geckos always want vertical space for climbing so use a tall tank rather than a long one. House geckos need climbable furnishings in their tall enclosures so provide branches, driftwood, and silk or live plants.
Common house geckos are from a humid subtropical climate, therefore, you will need to mimic this in their enclosures. Try to maintain a daytime temperature gradient of 75 to 90 F with a nighttime low of 65 to 75 F. Heat can be provided by utilizing ceramic heating elements or reptile bulbs in a reflector fixture.
Common house geckos are nocturnal, so they do not need as much special UVB lighting as day-dwelling reptiles. However, providing UV lighting to mimic sun rays is still beneficial to the overall health of nocturnal animals that sleep during the day. It is recommended to use a UVA/UVB light bulb during the daytime.
House geckos need a moderate to high humidity level in their enclosure so you will need to aim for 60 to 75 percent relative humidity which you can measure with a hygrometer. You should provide humidity with regular misting, a shallow bowl of water for evaporation, or a fogger.
House geckos should be fed a variety of small prey items. Crickets can make up the main part of their diet with the addition of fruit flies and other small flies, silkworms, the occasional mealworm, and other insects. You'll also need to gut-load the prey before feeding a gecko and dust the prey with a calcium supplement two to three times a week. Juveniles should be fed daily but adults can be fed every other day.
You can take care of a common house gecko!
All geckos can develop a metabolic bone disease (MBD), which is the result of insufficient dietary calcium and vitamin D. These geckos also get respiratory infections, including pneumonia. Seek out an exotic animal veterinarian who specializes in reptiles and especially lizards. Most geckos will recover from these maladies if they are treated in the early stages.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
