Crocodile Gecko


Your rating: None


Traits & behavior

This means they eat mostly live insects.

This means they're active during the day and sleep at night.

Crocodile geckos can be territorial, and are healthiest and happiest living alone.

Things to remember

Always supervise children when they're observing your crocodile gecko.

Crocodile geckos are very fast and have fragile skin, so it's best to limit handling them. Take care to never handle him by the tail - it could break off.

Food safety
Remove uneaten insects from the habitat at the end of the day; do not allow to remain in habitat overnight.

Safety & cleanliness
Please remember that all pets may bite or scratch, and may transmit disease to humans. Keep your pet's home clean and wash your hands before and after handling your pet or cleaning his home. Infants, young children, pregnant women, people with compromised immune systems, and the infirm or elderly are at greater risk of infections and should use caution when in contact with the pet or its habitat. Consult your doctor for more information.


Crickets & worms
Crocodile geckos eat live, "gut loaded" (feed the insects a special supplement so they have extra nutrients) crickets, mealworms or waxworms

Feeding frequency & amount
Feed juveniles twice a day; adults 3-4 times a week - offer an amount that can be consumed by the end of the day.

Calcium dust

"Dust" the insects with a calcium supplement twice a week - ask a PetSmart associate for details.

Provide drinking water in a shallow dish and change it daily.

Use a 20-gallon or larger, tall glass terrarium with a screen lid for proper ventilation.

Thoroughly mist the habitat daily to maintain a humidity level at 50%-70%. Use a hygrometer (humidity gauge) to help you keep track.


  • Day - Maintain a daytime temperature between 75-85° F
  • Basking - Use basking lamp to create a localized area of 90-95° F
  • Night - Maintain a nighttime temperature between 65-75° F
  • Place a thermometer at each end of the home to monitor temperatures

Plants Use artificial or live plants such as a pothos or ficus to create hiding, climbing and basking areas.

Use a daytime UVA/UVB fluorescent bulb for approximately 12 hours of light per day to help your pet process calcium.

Line the home with a 2"-3" layer of bark bedding or calcium sand. Clean out waste weekly and change bedding at least once a month.
