Do House Spiders Drink Water? Fun Facts About Your Average Spider

House spiders, like any other living creature, need water to survive. They get most of the water they need from the insects they eat, but you can also find them near water sources, like sinks and bathtubs, where they drink from droplets or puddles.

These spiders are not aggressive and usually only bite humans if they feel threatened. If you have a fear of spiders, don’t worry too much about these little guys – they’re more scared of you than you are of them!

If spiders don’t get the water their body needs, they risk dehydration and death. Most spiders can survive without water for up to 2 months, but they will be weaker and more susceptible to predators during that time.

Do House Spiders Need Water?

House spiders may be one of the hardiest living creatures on Earth, but they still need water to survive. Water plays a crucial role in a spider’s life, providing them with the hydration they need to live and hunt. It helps transport nutrients and oxygen around their body and keeps their joints lubricated.

While most spiders get the majority of the water they need from the insects they eat, they will also drink from droplets or puddles of water when they can. If you find a spider in your sink or bathtub, it’s likely because they’re looking for a drink.

Dehydration is a serious threat to spiders, and similar to humans and other living creatures, it can quickly lead to death when dehydration kicks in. Most spiders can survive without eating for months. However, they can only last up to 8 weeks without water on average. This still depends on the spider species, as the ones usually found in the desert can live without water for much longer periods.

Water Sources: Where Do House Spiders Drink?

House get water from various sources, depending on the spider species and their habitat. Most spiders will drink from any water source they can find, including rain puddles, dew on leaves, or even the water droplets that condense on the sides of their webs.

Some spiders will also build “water traps” near their prey to attract insects looking for a drink. These traps are made of silk and are often hidden near leaves or other objects. The insect will become tangled in the trap as they try to drink, making it easy for the spider to catch their next meal.

For pet house spiders, it’s a different story. Assuming your spider isn’t able to catch their own food, you will need to provide them with a water dish. The best way to do this is to fill a shallow dish with water and place it in their enclosure.

You can also mist the sides of the enclosure with water, but be careful not to make it too wet as this could create mold or mildew.

How Do Spiders Drink Water?

Spiders are strange creatures, with their long legs and beady eyes. But one of the strangest things about them is the way they drink water. Spiders have what are called “internal muscles” that allow them to suck water up through their bodies and into their mouths.

This process is called “osmosis.” When a spider drinks water, its internal muscles contract and pump the water up through its body. The water then flows into the spider’s mouth, where it can be used for hydration or for making spider webs. While this process may seem strange, it’s actually quite efficient and allows spiders to drink water without using their legs.

How Long Can House Spiders Survive Without Water?

On average, most house spiders can survive up to 8 weeks without water. But there are many other factors depending on the species, humidity, and temperature.

Daddy Long Legs

Daddy long legs, or cellar spiders, are some of the longest-lived house spiders. They have the ability to regulate their water and metabolic needs. Because of this, they can survive up to 2 months on average without feeding and drinking.

American House Spider

Similar to daddy long legs, American house spiders can store food and water for long periods of time. They typically live for around a year, but can survive from 3 to 8 weeks without food and/or water.

Brown Recluse

The brown recluse is one of the most feared spiders because of its venomous bite. But what many people don’t know is that this spider can actually go without food and water for up to SIX MONTHS! This is due to their extremely slow metabolism and ability to survive in dry conditions.

Hobo Spider

The hobo spider, characterized by its brown and hairy appearance, can live for up to 3 weeks without food and water.

Wolf Spider

Known for their large and intimidating size, wolf spiders usually can live up to 7 days without any water. If they do reach the 7-day limit, it’s known that these spiders are already pushing their limits and are in danger of dying.

Jumping Spider

Jumping spiders, as their name suggests, are able to jump long distances. Adult jumping spiders can live for one month without a food source, but they typically die within a week if they don’t have access to water.

Why Do Some People Think That Spiders Don’t Drink?

Spiders are often maligned creatures, feared by many people despite their harmless nature. One of the most common myths about spiders is that they don’t drink water. It’s easy to see where this idea comes from – spiders don’t have mouths like we do, so how could they possibly drink?

However, spiders do consume water, though they don’t do it in the same way that we do. instead of using their mouths, spiders absorb water through from their prey, or from dew and raindrops that they collect on their webs.

They don’t need as much water as other creatures because they are mostly made up of water themselves – a spider’s body is approximately 60-75% water.

Final Thoughts

Even if we don’t see them drink often, it doesn’t mean that spiders don’t need water to survive. Depending on the species, spiders can live for anywhere from a week to six months without food or water. They drink their predator’s fluids, dew from their webs, and raindrops.
