As the number of people keeping pet tarantulas continues to increase rapidly, the number of questions that we have seen people asking about keeping a pet tarantula has also been increasing over the last couple of months.
One thing that often worries people who are new to keeping a pet tarantula is when their new pet refuses to eat.
This is why we see so many people reaching out with various questions about how long a tarantula can live without food each month.
For the most part, this will actually depend on a number of different factors as different types of tarantula are different so there is no one size fits all answer to this and the actual reason that your tarantula is not eating can be different from tarantula to tarantula too.
This is why we have decided to publish this dedicated article going over how long a tarantula can live without food to try and help as many of our readers as possible who are having problems with their tarantula not eating.
What Happens If A Tarantula Doesn’t Eat?
In many cases, a tarantula that doesn’t eat will usually be fine due to how little energy a healthy tarantula will use up each day.
Some types of tarantula have been known to literally go years without eating without issue but this is very rare and usually specific to a small number of tarantulas.
The actual reason that your tarantula won’t eat will also come into play on what happens if a tarantula doesn’t eat too.
If your tarantula is just refusing food due to it needing to molt then there won’t be much of a long term problem with your tarantula and it will usually eat normally again soon.
If your tarantula is not eating due to having problems with internal parasites or health issues then this can be totally different and you may find that your tarantula can quickly develop serious health issues.
Due to this, we usually recommend that you try to take your pet tarantula to see a vet as soon as possible to try and get some confirmation on the potential issue with your tarantula and get any required treatments quickly.
How Long Can A Tarantula Live Without Food?
Some tarantulas can live for a surprisingly long time with minimal issues without food but many people who are new to keeping tarantulas are usually not aware of this.
The most common things to factor in when it comes to a tarantula not eating are:-
- The age of the tarantula.
- The sex of the tarantula.
- The type of tarantula you have.
- Any prior health conditions your tarantula has.
- The environment that your tarantula is living in.
- If the tarantula is due a molt or not.
- What your tarantula’s diet is usually made up of.
These all play a role in how long your tarantula can live without food before it starts to have some serious issues so it is usually better to take a more in-depth look at the various types of tarantula to try and offer some more specific advice.
Due to this, we will be going over the more commonly kept types of tarantula that are commonly kept as pets below to try and offer you more specific advice.
That said though, as we mentioned earlier in the article, if you are worried about your pet tarantula not eating then you really should be looking to take it to see a vet as soon as possible.
How Long Can A Juvenile Tarantula Go Without Eating?
When it comes to juvenile tarantulas, their food intake is usually more important than an adult tarantula due to the amount of growing they need to do.
Although the general recommendation is to try and feed a juvenile tarantula every couple of days, this is not the best advice to go by.
In our opinion, you should be trying to monitor the size of the abdomen on a juvenile tarantula and then try to feed it once the tarantula’s abdomen starts to shrink again.
Depending on the specific type of tarantula you have, this time frame can take anywhere from a couple of days to a week but the shrinking of the abdomen is usually the best indicator of when your juvenile tarantula will need to be fed again.
Just keep in mind, some types of tarantula can molt as often as once every three to four weeks when they are juveniles with this playing a role in short dietary breaks in when your tarantula will eat.

Once male Mexican red knee tarantulas get to around four or five years old, they usually stop molting and will have a more consistent eating pattern.
Female Mexican red knee tarantulas will continue to molt for longer than the males but once the are a couple of years old their growth rate tends to slow so they will molt less frequently reducing the interruption to their diet.
Mexican red knee tarantulas can be extra quirky as far as tarantulas go and this can cause your Mexican red knee tarantula to stop eating randomly for no apparent reason.
We have seen multiple people report that their Mexican red knee tarantula suddenly stops eating and just holds up for a couple of weeks or even months for no apparent reason only to start eating again at random.

The majority of curly hair tarantulas will want food once per week, sometimes twice depending on their ages and it is rare for them to go for more than two months without eating at all.
