Spiders are among the most misunderstood creatures in the insect world (technically, they’re arachnids). Often associated with fear and myths, spiders are actually essential in maintaining ecological balance by keeping pest populations in check. But a common question many homeowners have is: how long do spiders live without food or water? Understanding the survival behavior of spiders not only satisfies curiosity but also helps property owners stay proactive in pest prevention and home hygiene.
How Long Can Spiders Live Without Food?
When it comes to food, spiders are remarkably resilient. While their exact lifespan without food varies by species, many spiders can survive for weeks or even months without a meal. Factors that influence this include the spider’s age, species, size, environment, and prior nourishment.
For example:
- Adult house spiders can live several months without food.
- Jumping spiders, due to their higher metabolism, may last only a few weeks.
- Tarantulas and other larger species can go for months without eating, particularly in colder seasons when prey is scarce.
Spiders enter a low-energy state called torpor when food is unavailable. This state helps conserve energy, allowing them to wait until prey becomes available again. Some even intentionally fast during molting or reproductive cycles.

Can Spiders Survive Without Water?
While spiders can go for long periods without food, water is a different story. Most spiders still require hydration to survive, though the amount and method of water intake can vary.
Spiders typically obtain water in one of the following ways:
- From the prey they consume, which often provides enough moisture.
- By drinking dew or condensation in their environments.
- Some desert species even extract moisture from sand particles or the air itself.
On average, a spider can live for 1-2 weeks without direct access to water, though again, this varies depending on environmental humidity and species type. In humid environments, spiders can last longer without needing to drink water directly. However, in dry indoor conditions or arid climates, spiders may not survive long without some form of moisture.
Why Are Spiders in Your Home in the First Place?
If you’re spotting spiders around your home, it’s usually a sign that other pests are present. Spiders are drawn indoors in search of food sources such as ants, flies, and roaches. They prefer quiet, undisturbed corners, garages, attics, and basements where these prey are plentiful.
They are also more likely to seek shelter indoors when outdoor conditions are harsh, such as during:
- Extreme heat or cold
- Heavy rainfall
- Dry seasons where insects (their prey) are scarce
So, while you may not see spiders drinking or eating frequently, their presence often points to a larger pest control issue.
Should You Be Worried About Spiders?
Most spiders are harmless and actually beneficial by reducing the populations of other insects. However, a sudden increase in spider activity might be a signal to investigate and address an underlying pest problem.
Here’s what to look for:
- Webs in corners or around windows
- Egg sacs
- Sightings of small insects or bugs in your home
- Frequent spotting of spiders, especially near light sources or water
If spiders can find regular access to prey or moisture in your home, they’re likely to stick around. Left unchecked, this can create discomfort or even lead to bites in rare instances.
How to Prevent Spiders from Settling In
To make your home less attractive to spiders:
- Seal cracks and crevices around windows, doors, and foundations.
- Declutter storage areas, basements, and garages.
- Remove webs as you find them this disturbs spider habitats and encourages relocation.
- Control other pests reducing their food source will make your home less appealing.
- Use professional Leander pest control services to get to the root of the issue.
Consistent cleaning and maintenance play a significant role in keeping spiders and other pests at bay. But for complete peace of mind, especially in spider-prone areas like Central Texas, partnering with a professional pest control provider ensures ongoing protection.
What Happens to Spiders During Starvation?
Spiders without access to food or water don’t die immediately. Instead, they undergo metabolic changes:
- Lower energy output
- Reduced movement
- Minimal web-building or hunting activity
Eventually, without sufficient nourishment or hydration, the spider will succumb to dehydration or organ failure. Interestingly, some spiders will cannibalize smaller or weaker spiders in the same area to survive longer yes, it’s a spider-eat-spider world.
Spider Infestation or Just a Few Stragglers?
One or two spiders in a home are common and not usually a cause for concern. However, regular sightings, egg sacs, or web clusters may indicate a larger issue. That’s when it’s time to contact a trusted pest control Leander TX provider who can assess the situation and create a tailored plan.
