Tarantulas need water to survive, but they don’t need water daily for survival. If you own a tarantula, then it’s best to keep a water dish to keep it hydrated. Just know that it doesn’t require great amounts of water to survive.
In the wild, tarantulas survive just fine without water dishes. They get most of their water through their prey, as they get moisture from prey. They also rely on rain, water puddles, and other water sources they can find in nature.
Do Tarantulas Need Water?
Yes, tarantulas will need water to survive. However, they only require small amounts and they’re capable of getting it from the environment easily.
When tarantulas hunt, they will go after animals that can provide them with the most nutrients possible. This also means they’ll use all the resources they can get from their prey, including moisture.
Often, this moisture will be enough for the tarantula to keep hydrated for a long time. But if there is not an abundance of food and if the prey is relatively small, then the tarantula will look for other sources of water for survival.
The tarantula will look towards water puddles, rain, and other sources of water in nature for hydration.
Alternatively, they can also rely on morning dew that collects on the leaves of plants, so they’ll suck on the leaves to get their intake of water. This will suffice to keep them well hydrated for quite a long time.
If you’re a tarantula owner, then it’s still best to keep a water dish for your spider, though. This will make their life much easier as they won’t have to rely on the food you give them for hydration.
Whenever they feel thirsty, they will start drinking from the water bowl, which will keep them well hydrated for a long time.

When a tarantula is dehydrated, you will see symptoms such as:
- Wrinkled body
- The tarantula will shrink in size

If you notice any of the above-mentioned symptoms, you must provide your tarantula with water immediately. Placing a bowl or a water dish next to the tarantula should do the trick in this case.
Tarantula dehydration can occur after a prolonged period without water. A tarantula can go up to four weeks without water and still be fine, especially if you feed them foods that have a lot of moisture inside. However, anything longer than that without a real source of water can cause dehydration.
The best and only treatment for dehydration is water. So these symptoms should be a clear sign for the owner to provide water immediately, or else the tarantula is going to perish soon.
If you see the signs of tarantula dehydration, then you could try providing it with a water dish. However, it may not be the case that your tarantula is dehydrated. If the tarantula is not interested in water, then it could be a worse prognosis. In that case, seek the help of a vet that specializes in small pets.

How to Provide Water for a Tarantula
The best way to provide water for a tarantula is to keep a water dish near the tarantula that the spider could use occasionally to get hydrated.
You don’t need to do anything else but keep the water dish near the tarantula. Occasionally, you should change the water if it starts to get dirty, which will provide a good, healthy source of water for your spider.
An important thing to keep in mind is that you should not use a water dish or bowl that is too deep, or else the tarantula could drown inside the dish.
You must make sure that the water level is not higher than the body of the tarantula, or else you’re running the risk of having your tarantula struggle to drink water or even drown.
As a general rule, you should aim to replace the water in the water dish at least once a week. The tarantula is fine with having dirty water, but it’s optimal for the health of the tarantula to ensure that it gets the cleanest water possible. Some tarantula owners even swear by giving their tarantula rainwater.
How do Tarantulas Drink?
Tarantulas drink by using their mouths. They will submerge their chelicerae into the water, and then start drinking the water with their mouths.
Tarantulas have straw-like mouths, which makes it easier for them to suck up fluids. To drink water, they will submerge to drink with their mouths directly, which makes it easier for them to drink smaller amounts of water at once.
This is why you mustn’t provide them with water dishes that are too high or have too much water. The tarantula will need to submerge to drink, so if the water levels are too high, it might struggle to drink. In that case, the tarantula might even drown if the water is too high.
Tarantulas will drink water once every few days when it feels the need to hydrate. It will not drink often, but when it wants to, it should have a water supply ready nearby that would help it get hydrated easily.
