Do Tarantulas Drink Water

Many people, especially new tarantula owners, often wonder if these fascinating creatures need to drink water. While it may not be immediately obvious, tarantulas do indeed require water to survive and thrive.

In fact, water is much more important to them than food, as they can go days or even weeks without nourishment, particularly during mating season or when preparing for a molt.

Tarantulas can acquire water not only from a dish or water source placed in their enclosure but also through humidity in their environment.

High humidity levels provide essential hydration to these creatures, helping them stay healthy and comfortable.

In nature, tarantulas might drink from puddles, the bases of plants, or even raindrops that have collected on leaves and other surfaces.

So, the next time someone asks if tarantulas drink water, you can confidently inform them that it plays a critical role in their survival and health.

Do Tarantulas Drink Water?

Yes, tarantulas do drink water. In fact, water is more important than food for these creatures, as they can go days or weeks without food, especially during mating season or before molting.

Tarantulas obtain hydration from various sources, with drinking water being only one of them. Humidity also plays a significant role in keeping tarantulas hydrated.

Tarantulas typically do not consume large amounts of drinking water.

In the wild, they may drink from puddles, the bases of plants, or even raindrops that settle on plants and other surfaces.

It is vital to provide pet tarantulas with fresh drinking water, as they can die from dehydration without access to water.

How Tarantulas Drink Water

Tarantulas do drink water and need it to survive.

They obtain it in different ways such as from their food, humid air, or substrate.

When it comes to drinking water from a dish or bowl, tarantulas have their own unique way of doing it.

Their actual drinking process begins with the tarantula getting as close to the water source as possible.

They will then balance themselves carefully to ensure they don’t fall into the water.

Once stable, they lower themselves so that their chelicerae, the mouthparts near their fangs, touch the water.

The tarantula’s mouth is located behind their fangs and they use it to “sip” water in small amounts with the help of little mouths present behind their chelicerae.

This method ensures the tarantula stays hydrated and healthy.

When setting up a water dish for a pet tarantula, it’s important to choose a shallow dish large enough for them to submerge their chelicerae and fangs into it without the risk of drowning.

Small rodent or reptile water dishes can be suitable alternatives for providing water to tarantulas.

How Often Do Tarantulas Drink Water?

Tarantulas are known for their ability to survive without water for long periods.

However, they still require water to live, and it’s essential to provide them with a source of hydration.

The frequency at which tarantulas drink water varies depending on several factors, including their size, species, and environment.

Most tarantulas get their water from their prey, which is usually insects. They extract the moisture from their prey’s body and use it to hydrate themselves.

However, this method of hydration may not be sufficient, especially in captivity, where the tarantula’s diet may not be as varied as in the wild.

Therefore, it’s essential to provide a water source for your pet tarantula. You can use a shallow water dish or a damp substrate to increase the humidity in the enclosure.

However, it’s crucial not to make the substrate too wet, as it can lead to mold growth and other health issues.

As for how often tarantulas drink water, it depends on several factors.

Generally, tarantulas can go for weeks or even months without drinking water, as long as their environment provides enough moisture. However, it’s still important to check their water source regularly to ensure that it’s clean and fresh.

Some species of tarantulas, such as the Mexican Red Knee, are known to drink water more frequently than others.

These species may require a water source more often, and it’s essential to monitor their hydration levels closely.

In conclusion, tarantulas can survive without water for long periods, but it’s still crucial to provide them with a source of hydration.

The frequency at which they drink water varies depending on several factors, but it’s essential to monitor their water source regularly to ensure that they are adequately hydrated.

How Much Water Do Tarantulas Drink?

Tarantulas require very little water. In fact, providing too much water can be harmful to them.

It is important to note that tarantulas do not drink water frequently. They may only need to drink once a week or even less often.

In some cases, they may go months without drinking. This is because tarantulas can store water in their bodies and do not require frequent hydration like other animals.

How to Provide Water to Tarantulas

Tarantulas require access to water to maintain their health and well-being.

Providing water to tarantulas is a simple process that can be accomplished in a variety of ways.

Here are some common methods for providing water to tarantulas:

Water Dish

One of the easiest ways to provide water to a tarantula is by using a shallow water dish.

The dish should be small enough to fit inside the tarantula’s enclosure without taking up too much space.

Fill the dish with clean, fresh water and place it in a location where the tarantula can easily access it.

Make sure to clean and refill the dish regularly to prevent bacterial growth and ensure that the water remains fresh.


Some tarantulas prefer to drink water droplets from the sides of their enclosure or from plants.

Misting the enclosure with a spray bottle can provide the tarantula with access to water droplets.

However, it’s important not to over-mist the enclosure, as high humidity levels can be harmful to some tarantula species.

Food Hydration

Many tarantulas obtain water through the food they eat. In the wild, tarantulas often prey on insects and other small animals that contain a high water content.

In captivity, feeding tarantulas fresh fruits and vegetables can help keep them hydrated.

However, it’s important not to overfeed the tarantula or provide it with foods that are high in sugar or fat.

Why is my tarantula not drinking water?

One of the main reasons is that tarantulas get most of their moisture from their food rather than directly drinking water.

Insects they consume, like crickets and mealworms, consist of a high percentage of water, which helps in keeping your tarantula hydrated.

Moreover, tarantulas are more likely to drink water post molt when they lose the most moisture.

Another factor to consider is that tarantulas are nocturnal creatures, meaning they are active during the night, and this might be when they’re drinking water.

So, if you’re observing your tarantula during the day, chances are you won’t see them drinking.

Also, tarantulas are generally secretive animals, and they might prefer to drink water when they feel unobserved and safe.

Signs of Dehydration in Tarantulas

Behavioral Signs

Tarantulas are not very active creatures, but they do have some behaviors that could indicate dehydration.

One of the most common signs of dehydration in tarantulas is sluggishness.

A dehydrated tarantula may move slower than usual or may be less active than normal. They may also be less responsive to stimuli, such as touch or movement.

Another behavioral sign of dehydration is a lack of appetite.

Tarantulas may go for extended periods without eating, but if a tarantula is dehydrated, it may refuse food for even longer periods of time.

Physical Signs

Physical signs of dehydration in tarantulas are more noticeable than behavioral signs.

One of the most obvious signs of a dehydrated tarantula is a smaller than normal and shriveled abdomen.

It looks like the abdomen is sunken in and wrinkled.

Another physical sign of dehydration in tarantulas is a lack of urination.

Tarantulas typically excrete waste in the form of uric acid crystals, which are visible as white deposits in the tarantula’s enclosure.

A dehydrated tarantula may produce little to no uric acid crystals, indicating that it is not drinking enough water.

Dehydrated tarantulas may also be more prone to shedding problems.

When tarantulas are dehydrated, the exoskeleton may not separate from the new skin properly, leading to problems with molting.

In conclusion, it is important to be aware of the signs of dehydration in tarantulas.

A dehydrated tarantula can become seriously ill or even die if not treated promptly.

If a tarantula is showing signs of dehydration, it is important to provide it with fresh water and monitor its behavior and physical condition closely.


Tarantulas are fascinating creatures that require proper hydration to thrive. They can drink water from a dish, but they also get moisture from their prey. It is important to provide a clean water source for tarantulas to prevent dehydration and keep them healthy.

Tap water is generally safe for tarantulas as long as it is safe for humans to drink and does not have an unpleasant taste or odor.

However, it is important to research the specific needs of your tarantula species to ensure that they are getting the proper hydration they need.

While there is some controversy over whether or not tarantulas need water dishes, providing one can have benefits for the spider’s overall health and well-being.

Water dishes can also help maintain proper humidity levels in the tarantula’s environment.

Overall, providing a clean water source for tarantulas is an important aspect of their care.

By understanding their unique hydration needs and providing a suitable water source, tarantula owners can ensure that their pets remain healthy and happy.
