How Long Can A Wolf Spider Live Without Food?


On average, a spider will eat up to 3,000 insects per year. This may seem like a lot, but it’s actually not that much when you consider how many insects there are in the world.

Because wolf spiders are relatively large, their diet is usually very high in protein and fat. Which allows them to survive for weeks at a time without little to no food.

But, how long can a wolf spider live without food exactly? Well, this question is a bit tricky as it depends on the age, size, and sex of the wolf spider.

Typically, a full-grown adult wolf spider can go for one month without any food. However, at this point, the spider will be weak and will look very thin as it will be feeding off its own body reserves.

How Long Can Baby Wolf Spiders Live Without Food?

While adult wolf spiders are generally quite resilient when it comes to going without food, young baby wolf spiders are much more vulnerable and will struggle with this.

In general, most baby wolf spiders will only be able to survive for a week without eating any food. This is because hatchlings need a lot of protein and nutrients that they typically get for their prey in order to grow and develop properly!

If baby wolf spiders don’t eat enough food they will become malnourished, which can have a significant impact on their health.

What Happens To A Wolf Spider When It’s Starving?

When a spider goes without food for too long, it can have a huge impact on its health, and the mighty wolf spider is no exception.

Although wolf spiders can last longer than your average house spider, they can still experience negative effects when starving.

Some of the most common symptoms that a wolf spider experiences when starving includes:

  • Weight loss: Since they are unable to find any food, wolf spiders will begin to lose weight and body mass over time. This is because they continue to use stored fat to create energy even when they are not eating.
  • Reduced Mobility: As their energy levels decrease and their muscles begin to weaken, the wolf spider will become less mobile and struggle to hunt for prey.
  • Change In Behavior: As the wolf spider becomes hungrier and weaker, its behavior will change. For example, the Wolf spider will be more notable during the day which is not normal for these spiders and some may even become more aggressive.
  • Loss Of Coordination Or Balance: Wolf spiders may also experience problems with their coordination and balance, especially when they are walking, which can make it difficult for them to capture prey and defend themselves.

Do Wolf Spiders Often Go Without Eating?

While there may be some wolf spiders that go without eating for a few weeks or months, most will do their best to find food as quickly as possible in order to survive.

In general, wolf spiders are very good hunters and tend to have high rates of success when it comes to capturing prey. As such, they rarely experience long periods of time without food.

However, there are some situations where a wolf spider may struggle to find food.

For example, if their normal hunting grounds have been disturbed due to natural disasters or human activities, they may be forced to go for longer periods of time without eating.

Additionally, if the prey in their environment becomes scarce, it may be difficult for them to find food on a regular basis.

Last Resort!

If the wolf spider’s prey starts to drop in numbers and is becoming harder to find then it may need to take drastic measures in order to survive. At this point, the wolf spider will be forced to turn to “cannibalism”, eating its own kind.

However, this is typically a last resort for wolf spiders, as it can be extremely dangerous and can lead to injury or even death.


So, how long can a wolf spider live without food? As before, the answer varies depending on the individual spider and its environment but, in general, wolf spiders are incredibly resilient creatures that can go for long periods of time without eating.
