House Spiders Can Survive Outside: Fact or Myth?

For people who were never fond of having spiders inside their homes, considering relocating them outside may seem like an act of compassion. Is there a truth behind this?

The truth is, while house spiders can technically survive outside, it’s not likely they will for long. House spiders are used to living in the warm, humid conditions that are found inside most homes.

When they’re suddenly exposed to the elements – such as cold weather, rain, or snow – it can be quite a shock to their system. Take note, however, that not all house spiders can survive the outdoors. It depends on the species.

There are some hardy house spider species that can withstand living outside for short periods of time. But even then, they will eventually start to feel the effects of being in an environment they’re not used to.

Additionally, house spiders are what’s known as “opportunistic feeders.” This means that they’ll eat just about anything they can get their hands on – including other bugs, like ants and flies. However, these same opportunistic eating habits also make them more likely to starve to death if they can’t find enough food.

So, while you may feel like you’re doing a good deed by releasing a house spider into the wild, odds are it’s not going to end well for the spider. House spiders play a critical role in keeping homes free of pests. It’s like having a natural pest-control system right in your own home.

Which House Spiders Can Survive Outside?

Many people are surprised to learn that not all spiders can survive outside. While most species of spiders are perfectly content to live in the comfort of your home, there are a few hardy types that can endure the rigors of life in the great outdoors. Let’s find out:

Wolf Spider

They are also very agile, making them difficult for predators to catch. In addition, wolf spiders have excellent eyesight and are able to see in low-light conditions.

Their ability to hunt effectively in any environment makes them well-suited for life outside the home.

Do House Spiders Go Back if You Take Them Outside?

Some people are tempted to take their house spiders outside, thinking they will be doing them a favor. However, this is not the case. While it’s true that some may make it and survive the outside world for a while, most will not.

And even if they do survive, it won’t be for long. House spiders are not equipped to deal with the rigors of life outside and will eventually succumb to starvation or predators.

When you take a house spider to your backyard, for instance, it could find a crevice to hide in. It could be back to your home, or somewhere near it, in a few hours.

If you live in an area with many predators, the spider may not be so lucky. Spiders that are taken outside are more likely to become prey than to find their way back home.

These home spiders may likely feel disorientation, fear, and even stress when outside. They will also be more prone to dehydration since they’re not used to the heat or the direct sunlight.

There are different factors that can take effect on a spider’s survival outside your home, and most of them are not in the spider’s favor.

Final Thoughts

In conclusion, while a few house spiders can survive outside, most will not. If you take a spider from your home and release it into the wild, it is unlikely to survive for long.

House spiders are simply not equipped to deal with the hazards of the outdoors. If the spider doesn’t pose a threat to you or your family, the best thing to do is to leave it alone.

A single spider inside your home won’t cause any harm. In fact, it is more likely to help you by preying on other insects that might be pests.

If you have a spider problem, the best solution is to call a professional exterminator. They will be able to safely and effectively remove the spiders from your home.
