Where do Spiders Come From? A List of Spider Entryways in the House

Spiders are tiny, so they have a lot of ways to enter human homes.

Doors and Windows 

The most obvious culprits are the entryways we use ourselves. Doors and windows have welcomed spiders inside our houses for as long as anyone can remember. With huge gaping holes that lead them indoors, spiders are free to enter and leave whenever they want to.

To combat this, install properly fitted fine mesh screens into your doors and windows. Thick curtains block out the light from the inside, keeping flying insects out and the spiders that prey on them out as well. You can also attach sweeps or cinch door seals for those annoying gaps at the bottom of your doors.


If you have spiders in your home and everything’s been sealed off, the most possible scenario is that you brought those eight-legged creepy crawlies with you.

Just like bed bugs, spiders are good hitchhikers. They can hitchhike inside storage boxes, furniture, toys that stayed out a little too long on the yard, camping and trekking equipment and even in jackets. So make it a habit to routinely inspect your things, even your clothes, before entering your house.

Potted Plants

Speaking of hitchhiking, spiders are notorious for hiding inside potted plants. They’d then emerge out of them some time after they’ve successfully infiltrated your home.

To avoid this, don’t leave your plants out for too long so that they won’t bring in unwanted guests. And you should thoroughly check them before bringing them in. That goes for bouquets and flower baskets too.

Cracks and Crevices

Cracks, gaps, crevices and lines along the wall can invite tiny spiders inside. These arachnids can also go through the holes that utility wires pass through. So make sure you seal every one of them with caulk.

Plants Near Your House

Where do spiders come from? Well, they can also come from overgrown plants that are now too close to your home’s walls, doors and windows. Branches, vines, shrubs and even thin wispy greens can turn into makeshift bridges for spiders, connecting the outside world to your warm and cosy house.

Unused Chimneys

If you don’t like using your chimney, chances are, you’ll get a lot of cobwebs inside it. So burn a few logs to stop the spiders from getting inside the living room. You can also fit fine mesh screens inside the chimney to keep the creepy crawlies out.

Air Vents

If spiders can’t get in through the windows, they’ll use the vents. Attracted by insect prey, they habitually explore secluded areas just to land on strategic hunting spots.

Your Yard

One of the most common reasons why spiders enter houses is that they’re already living in your yard. Venturing into your house is just something that they do to find food. After all, your home is conveniently near their dwelling spot.

Spiders outside usually stay underneath a pile of dead leaves, patches of grass, stacks of firewood, compost bins and rocks. So it’s always a good idea to keep the yard tidy and mowed down to control spider infestations.


As we mentioned above, a lot of spiders love to stay below stacks of wood. This is probably because wood is typically rich in moisture, and that attracts different kinds of insect. With this, the spider has plenty of prey to hunt and eat.

Keeping a pile of wood near your home invites spiders inside. With that in mind, position the wood a few feet away from the nearest door or entryway. You can also store them inside a shed, one that’s also a few feet away from your house.



Like woodpiles, crawlspaces also have abundant moisture inside them. So it makes sense why spiders love to build their webs inside crawlspaces. Having a weekly or monthly clean up on that part of your house will do wonders to an infestation problem.

The Garage

When you find spiders literally hanging from somewhere in your house, another tendency is that they didn’t sneak their way inside. They came from one of the rooms in your house, specifically, from a very cluttered and messy garage.

Garages have a lot of things kept inside them, so there are plenty of hiding spots for spiders. You also have that big door that’s constantly kept open all the time.

What you should do here is to apply repellents since you really can’t afford to keep the garage door permanently closed. You should also try to keep a clean space where there’s less clutter and less mess for the spiders to exploit.

The Attic and Basement

Finally, we have the attic and basement. These rarely used rooms are home to a lot of tools, boxes and unwanted junk. If you have a hard time looking after them, then you undoubtedly have spiders crawling somewhere inside them. Like your garage, you should declutter and clean up your attic and basement to get rid of these arachnids.

So that’s it, a complete list that answers the question we raised earlier – Where do spiders come from? By reading this, you can now thoroughly plan out strategies that will ultimately help your house become spider-free in the near future.
