Should I Sleep If There’s A Spider in My Room?

Last Updated on February 11, 2024 by Louise Carter

You’re not alone if you’re horrified when you see a spider in your bedroom. The bedroom is supposed to be our sanctuary, but up to 15% of people have arachnophobia.

Of the 4,000 spiders native to the U.S., just 5 species bite humans.

If you’re afraid of spiders, an arachnid in the bedroom will prevent you from sleeping. If so, the spider should be removed. If you’re not scared of spiders, you can go to sleep as they rarely approach humans.

Spiders will remain in a bedroom if they have a reliable food source and feel safe.

If you want to keep spiders away while you sleep, keep the bedroom bright and tidy, seal cracks in walls, keep windows closed, and use peppermint oil because spiders detest the smell.

Is It Safe To Sleep with A Spider in The Room?

A spider is unlikely to approach while you’re asleep because they fear humans. You can adopt a live-and-let-live policy if you’re unafraid of spiders and the species isn’t venomous.

Not everyone likes spiders. According to the Bulletin of the Entomological Society of America, spiders (arachnids) are the third most common phobia in the U.S., behind snakes and rats.

If you’re an arachnophobe, the presence of a spider will likely prevent you from sleeping soundly. Therefore, the spider should be removed from your bedroom before you go to bed.

How Long Will A Spider Stay in Your Room?

A spider will stay in your room until you physically remove it or make the terrain inhospitable. Typically, spiders will be found in a bedroom for the following reasons:

  • Clutter. Spiders love hiding places. If your bedroom is messy, a spider will have plenty of opportunities to mask its presence.
  • Darkness. Spiders like corners where they won’t be disturbed, making closets a favored location.
  • Warmth. Spiders come inside during the fall and winter when it is cold outside. Keeping your bedroom cool will aid sleep and deter spiders.
  • Moisture. While spiders dislike damp and moist conditions, much of their prey favors them. Spiders gravitate toward rooms where they’re likely to capture insects in their webs.
  • Crumbs and food remnants. If they can’t find an insect, spiders will eat other food.

If you want to banish spiders from your bedroom, make the area unappealing.

Will A Spider Lay Eggs in My Bedroom?

If a female spider feels safe in your bedroom and plans to remain there, she could lay eggs. Spiders can lay up to 300 eggs at a time, but the survival rate of spiderlings (baby spiders) is low.

Spider eggs can be dealt with by sucking them up with a vacuum cleaner or calling a professional exterminator. Avoid removing them with your hands as a precautionary measure.

Identifying Dangerous Spiders

Over 4,000 species of spiders live in the U.S., but just 5 have a venomous bite. These include:

Brown RecluseThe violin-shaped marking behind its eyes means that it’s often called the Fiddler Spider. Brown Recluse spiders aren’t aggressive but may bite if disturbed.
Black WidowThe Black Widow is identified by a red hourglass marking on its abdomen. On a like-for-like basis, this spider’s venom is 15 times stronger than a rattlesnake’s. Black Widow spiders are most active in spring and bite if threatened or their nest is disturbed.
Hobo SpiderIdentifiable by a yellow sac on its underbelly, this spider may hide in clothing and bite when startled. It’s the most active biter, but its venom is mild.
Wolf SpiderWolf spiders are over an inch long, covered in hair, and lightning fast. They rarely venture indoors, and their painful bite is rarely life-threatening.
Yellow Sac SpiderIdentifiable by a yellow sac on its underbelly, this spider may hide in clothing and bite when startled. They’re the most active biters, but their venom is mild.

A spider bite initially feels like an insect sting, so the skin is sore to the touch and swells. Spider venom can cause necrosis. If you suspect you’ve been bitten, head to the ER.

Unless the spider in your bedroom falls under these categories, it’ll be harmless and frightened by your presence. There’s no need to be afraid, but you may want to remove the spider before it lays eggs.

Safely Removing A Spider from A Bedroom

Call a pest control expert if you’re concerned the spider in your bedroom may be dangerous.

If you see a common house spider, resist the urge to swat it with a shoe or newspaper. It’s easy to erroneously attack a Hobo spider or Brown Recluse and get bitten.

Trap the spider in a glass or bowl and take it outside, or chase it out of your bedroom with a flashlight. Shining a beam directly at a spider will usually get it to move.

Will A Spider Crawl on Me in My Sleep?

It’s a cliché to say that spiders are more afraid of us than we are of them, but it’s true. Spiders will do anything to avoid directly interacting with humans because we’re much larger than them.

We must remember that spiders aren’t aggressive creatures, but they will defend themselves.

Sometimes, a spider may be attracted to the warmth a human body emits or fall from the ceiling when traversing the room. If so, spiders will usually run away and hide.

When a spider gets too close to a human, it’ll likely lose its nerve and flee, even if it smells food.

Will I Swallow a Spider in My Sleep?

A spider is very unlikely to approach your mouth while you’re sleeping. Spiders aren’t keen to approach humans, so it would take a brave spider to get close enough to be swallowed.

Even if a spider was drawn to your bed, perhaps due to leftover crumbs, your presence would deter it.

Spiders detect noises through vibration receptors on their eight legs. Every noise you make sets off these receptors and is marked as a potential threat.

If you roll over in your sleep, spiders will sense this and run away to avoid being crushed.

Spiders notice the change in the atmosphere and respond if you breathe heavily. Although you can’t hear yourself snoring or breathing, the sound will be detected due to a spider’s acute sense of hearing.

Imagine an unlikely turn of events where a spider drops from the ceiling straight into your open mouth and down your throat before you know it. The chances of this happening once are slim.

Even if you swallow a spider, your body will process, digest, and eliminate it as waste.

How To Protect Yourself from Spiders While Sleeping

If you’re still concerned about spiders in your room while sleeping, take these precautions:

  • Keep the room clutter-free to remove hiding places.
  • Open your windows and leave the lights on, as spiders want a dark place to hide from the sun.
  • Get an electric pest repellent that creates ultrasonic waves to keep spiders away.
  • Never eat in the bedroom, especially in bed.
  • Turn on the AC. Spiders have no interest in setting up a home in a cold and draughty environment.
  • Apply peppermint oil to pillows and blankets, as spiders hate this aroma and will steer clear.
  • Place a riser between your bed and the floor, and move your headboard away from the wall.

Above all, keep your bedroom tidy. The more frequently you deep clean a bedroom, including laundering the sheets and blankets, the less likely spiders will remain in your bedroom.

While arachnophobia is a common concern, don’t let it prevent you from sleeping.
