Green Tree Frog (Hyla cinerea) Care Sheet

Green tree frogs are found throughout the east coast and Midwest.  They are small frog and typically only reach 1-2 inches.  They are an arboreal species and can be found hunting for food at night, when they are most active.  Sexing these frogs is difficult and males are smaller than females.  Another way to determine sex is to listen to them, if you hear your frog calling or singing it’s definitely a male. 


Green tree frogs need to be maintained in the mid 70’s during the day.  Nighttime temperatures can drop into the low 60’s.  Normal household temperatures are fine and no supplemental heating will be necessary. UVB lighting is not necessary but is recommended for green tree frogs.  The UVB light will benefit any live plants and enhance the colors of your frogs.  Humidity is important and you should mist your cage every day in the evening hours.


Green tree frogs can be housed comfortably in 20-29 gallon or larger terrariums.  The cage should include plants (live or silk), branches and a water bowl.  Do not use distilled or purified water for any amphibians.  Never place a cage near a window where sunlight can directly shine on your cage.  Cages placed in direct sunlight can easily overheat and ultimately lead to the death of your frog. 


We recommend using bark, Zoo Meds’ Eco Earth, or coconut bark.  The substrate should be deep enough for potted plants if you choose to setup a live vivarium.


Green tree frogs should be fed appropriate sized crickets, waxworms, and fruit flies.  Ideally, you should feed your green tree frogs 3-5 times each week.  These frogs also need a vitamin/mineral supplement and you should dust its crickets at least twice a week. 

Cleaning and Handling

The terrarium should be cleaned as necessary. Any fecal matter or left over food should be cleaned out several times a week.  Fresh clean water should be provided at all times.  The inside of the terrarium can be cleaned out with an appropriate reptile cage cleaner, we recommend Natural Chemistry’s Healthy Habitat.  Green tree frogs can be handled on a limited basis and always wash your hands before and after handling them.
