Tarantula Care Sheet

Developed with and approved by a qualified veterinarian.

This care sheet covers a variety of tarantula species, including: 

  • Pink toe 
  • Red knee
  • Rose hair


Typical tarantula appearance & behavior 

  • If feeling threatened, they may bite or run  
  • As part of their natural defense, some may “flick” urticating hairs, which may cause an allergic reaction or skin irritation in humans 
  • Their bite is equivalent to a bee sting.  Some individuals may be especially sensitive. If bitten, seek immediate medical attention 


Care Difficulty Moderate
Average Life Span 2 to 10 inches,
depending on species
Average Adult Size Depending on the species and with proper care:
Up to 30 years (females)
Up to 7 years (males)
Diet Carnivore/insectivore
Minimum Habitat Size 10-gallon



Habitat size

An appropriately sized and shaped habitat at least three times their leg-span long and two times their leg-span wide is required to accommodate normal behavior and exercise. Minimum height for ground dwellers should be the length of the tarantula. Tree-dwelling tarantulas require a 10-inch minimum height.

Building your habitat 

  • Décor - Provide a place to hide such as a half log. Tree-dwelling tarantulas also need cork bark, branches and plants to build their webs.  
  • Substrate - Mulch-type substrate such as coconut fiber bedding, reptile bark or dampened sphagnum moss. Avoid gravel and artificial turf, which is too harsh for the skin 
  • Temperature - 68 to 82°F, depending on species. Use of an under-tank heater can help maintain appropriate habitat temperature 
  • Lighting - Keep in a darker part of the room away from sunlight. Avoid incandescent lights, which can dry out a tarantula. Use a low-wattage nocturnal or infrared light to watch your tarantula after dark 
  • Humidity - Maintain 40 to 90% humidity, depending on species, by misting as needed every day 

Cleaning your habitat 

Thoroughly clean and disinfect the habitat at least once a month, or more often if needed:  

  • Place tarantula in a secure habitat 
  • Scrub the tank and furnishings with a reptile habitat cleaner or 3% bleach solution 
  • Rinse thoroughly with water, removing all traces of habitat cleaner or bleach smell 
  • Dry the tank and furnishings and add clean substrate before placing the tarantula back in their habitat 


What Do Tarantulas Eat

A well-balanced tarantula diet consists of:

Things to remember when feeding your tarantula:

  • Fresh, clean, chlorine-free water should be available at all times (in a shallow bowl). Your tarantula may not drink from a bowl but will rely on moisture on plants 
  • Feed juveniles daily, adults every other day. Since they are nocturnal, feeding should occur at night 
  • Be sure that food is smaller than the tarantula. Remove any uneaten live food as it may cause injury to a resting tarantula 
  • Replace water daily 



Handling tarantulas is not recommended. If feeling threatened, they may bite or even run and fall. A short fall can cause a serious or even fatal injury.

When tarantulas molt, they lie on their back with their feet up in the air. Juveniles molt about four times a year and adults once a year. They may stop eating up to two weeks before a molt; do not disturb during this time. Be sure to remove all live food from enclosure, as even a cricket could harm them during this period.


Where to buy 

Tarantulas are available for purchase at your local Petco location. Please call ahead to check availability.




Tank mates 

Pink toe tarantulas are one species of tarantula that can sometimes be kept in groups if the habitat is large enough and all are well fed. House other tarantula species separately and do not house different invertebrate species together.
