Did you recently acquire a Tarantula? Now you wondering what pet Tarantulas eat? Tarantulas are insectivorous carnivores. They feed on a wide variety of insects in the wild. Bigger Tarantulas also feed on other smaller animals and other spiders.
Tarantulas are large hairy spiders classified under the family Theraphosidae. About 1,000 species of Tarantulas have been identified and their sizes and color vary widely depending on location and species.
But what do they eat?
What do pet Tarantulas eat?
We recommend feeding pet Tarantulas on crickets supplemented with other insects. If you have bigger Tarantulas you can feed them on pinky mice or small lizards.
Feeding of Tarantulas depends on their body size, their age and molting state. Ideally feed your Tarantula on prey that is smaller than their body size.
List of preys Tarantulas can eat at home
- Crickets – you can never go wrong with crickets as all Tarantulas love and eat crickets.
- Meal worms
- Super worms
- Roaches – such as Dubai roaches or cockroaches
- House flies
- Grasshoppers – feed to Tarantulas who are larger in size than the grasshopper
Bigger Tarantulas can be fed on other small animals such as;
- Pinky mice
- Baby rodents
- Small lizards
- Small birds or hatch-lings
- Small snakes
Make sure that the prey is smaller than the Tarantula.
Most Tarantula owners prefer to feed their tarantulas on a diet of crickets supplemented occasionally with other insects.
What do Tarantulas eat in the wild?
Tarantulas are nocturnal (active at night) carnivores.
In the wild, Tarantulas eat a wide variety of insects. Some larger species however may hunt mice, frogs, small lizards, small snakes, small birds or other spiders.
How do Tarantulas catch their prey?
Most spiders use webs to trap their prey.
Tarantulas are different. They prefer to actively ambush and pursue their prey. Tarantulas however may spin a trip wire to signal them when potential prey approaches their burrows.
Tarantulas use their strong jaws to grab and kill their prey. They then use their fangs to inject the prey with venom.
How do Tarantulas digest their food?
The Tarantulas venom contains chemicals that digest the preys flesh. Tarantulas also coat the body of bigger preys with digestive enzymes.
Tarantulas have short straw like mouths which make them unable to eat solid food. Once the prey is liquefied the Tarantula then sucks up the liquid using their straw like mouths.
Tarantulas have a large sucking stomach. When the muscles of this stomach contract, they create a sucking action that allows Tarantulas to suck the liquid from their dissolved prey.
These liquid is then broken into small particles in the intestines. The particles are then absorbed through the walls of the intestines into the Tarantulas bloodstream. They are then distributed throughout the Tarantulas body.
The tarantula then converts the left over prey into a small ball and throws it away.
How should I feed my Tarantula?
To feed your Tarantula, drop the cricket using a pair of round nosed forceps near your Tarantula.
DO NOT feed your Tarantula using your hands.
Tarantulas are snappy eaters. Feeding them using your hands can lead to Tarantula bites.
That would be nasty!!! read here to see if tarantulas are dangerous.
If you do not have a pair of forceps you can drop the prey into the terrarium.
Most Tarantulas prefer live prey. They rely on prey movement to spot their prey. You can poke the prey to provoke them to move so your Tarantula is able to spot them.
When should I feed my Tarantula?
Tarantulas are nocturnal hunters. They prefer to hunt at night.
It is advisable to feed your Tarantula in the evening or early in the morning when the spider is most active.
How often should I feed my Tarantula?
You can feed Adult Tarantulas once per week.
Juvenile or growing Tarantulas have more dietary requirements. You can feed them for as long as they will eat. They may need to be fed every day or every other day (Skip one day).
Growing Tarantulas molt more often. Do not feed them when they are molting.
As Tarantulas grow older their growth rate slows down. They may end up eating only once every 2 or 3 weeks
What size of food should I feed my Tarantula?
The ideal size of meal to feed a Tarantula is half its leg span or prey smaller than their body size.Some Tarantulas may however eat prey as big as their body size.
You can feed your tarantula 1 to 5 crickets per feeding depending on the size of the cricket and the size of your Tarantula.
When your Tarantula is full they will stop responding to the prey.
Check the abdomen size to know when your Tarantula is full. If the abdomen is twice bigger than the cephalothorax you should stop feeding him or her.
What about the left overs?
Remove any uneaten food within 24 hour of feeding. Crickets or other preys if uneaten and left in the burrow may disturb your Tarantula causing them to be stressed.
The crickets may also injure your Tarantulas who have delicate bodies.
Left over food should also be removed from the terrarium if your Tarantula is not interested in them anymore. These may start decomposing producing favorable media for bacteria and fungi that could harm your Tarantula.
Do tarantulas need water?
Tarantulas need a constant supply of clean drinking water.
In the wild they rely on dew and water droplets found on plants.
Provide a clean bowl of water at all times. Ensure that you change the water regularly.
The water bowl should be shallow to avoid the risk of your Tarantula falling into the water and drowning.
As a precaution and to provide support to your Tarantula, you can add some pebbles into the bowl of water.
Can Tarantulas eat fruits and vegetables?
Tarantulas are carnivorous animals. They rely on a diet of insects or other small animals in the wild.
To satisfy their water requirements, Tarantulas sometimes eat some fruits and vegetables.
You can try giving your Tarantula vegetables like carrots or fruits such as grapes, apples or pineapples to see if they will be interested in them. Do not make it a habit to feed them on this however.
Why is my Tarantula not eating?
Tarantulas may sometimes refuse to eat. There are many reasons why your Tarantula may refuse to eat including the following:
- If they recently had a large meal. Your Tarantula may simply be full. We recommend feeding Tarantulas once per week and to give them food smaller than their body size.
- Wrong prey. Tarantulas are fuzzy eaters and use prey vibration to pursue their meal. Some prey like the Dubai roach play dead when they feel threatened which may make your Tarantula lose interest on the meal.
- Molting. Tarantulas periodically change their exoskeleton in a process called molting. During the last few days before molting your Tarantula may abstain from food.
- Damaged fangs. If your Tarantula has damaged fangs, they may refuse to eat. Sometimes if Tarantulas have a meal too early after molting they may damage their fangs. Be careful not to feed your Tarantula too early after molting.
- Change of environment. Tarantulas suffer from depression when their environment is changed. They may refuse to eat when they are moved into a new environment. Therefore choose a terrarium that closely resembles the original habitat of your new pet Tarantula.
Do not be panic if your Tarantula refuses food for 2 or 3 consecutive feedings.
Tarantulas can survive for 1 month or more without food.
Raising insects to feed Tarantulas
It is important to note that you may have to keep Tarantulas together with some insects such as crickets or roaches to have a constant supply of food for your pet Tarantula.
You can keep the crickets or roaches in a separate Terrarium or pot. The enclosure should be kept closed to prevent the insects from coming out. Crickets require damp sand or soil.
Buy your first batch of breeding crickets from a pet store. Do not collect them from the street as they could be a source of disease to your Tarantula.
The crickets will have to be gut full. Meaning they have to fed on nutritious diets prior to being fed to Tarantulas. You may even dust the cricket with vitamin powder before feeding it to the Tarantula.
Note that crickets chirps are noisy and can be a nuisance to you or other residents in the house.
