Why Are Brown Recluse Spiders In Your House And Where They Hide?
Brown recluse spiders are outdoor spiders.
But they’re also adaptable enough to live and thrive in human dwellings.
Outdoors, brown recluse lives under rocks, organic debris, logs, and woodpiles.
Indoors, brown recluse spiders live in cluttered, dark spaces and areas where you don’t go often.
So, their hiding places are similar to those of a black widow’s.
Below are the 13 most common places in your home where brown recluse spiders hide, for sure –
- Crawl spaces
- Attics and cellar
- In the Voids and gaps on the wall-floor junctions
- Behind clutter and inside items like abandoned cardboard boxes and between piles of newspapers
- Behind walls
- In the crevices on the concrete blocks of your home’s foundation
- Above suspended ceilings
- Behind baseboards and headboards
- Inside ducts
- Inside shoes
In these places, there can be one or more brown recluse spiders.
Brown recluse spiders love to hide in cardboard and wooden boxes because they resemble a tree bark under which they’re accustomed to hiding outdoors.
Brown recluse spiders are resilient.
They can survive severe winters in an unheated basement and harsh summers in an attic.
Brown recluse spiders can also survive without food and water for months.
So, why do they get inside your home?
They get inside your house searching for an ideal hiding place and prey.
Brown recluse spiders sneak inside your house through the cracks on your home’s walls.
Other entry points are open windows and doors.
They can also sneak in through the gaps between the door and the floor.
Brown recluse spiders are nocturnal. Nighttime is the time when they hunt.
During the day, brown recluse spiders will retreat in their hiding places.
It’s unlikely to see a brown recluse spider during the day.
If you do, then it’s because it’s searching for a new place to hide, or it’s hungry, or due to pesticide application.
Many homeowners spotted brown recluse spiders in their bathrooms, especially in the bathtub and sinks.
So, they believe that brown recluse spiders can sneak in through the drains.
Brown recluses can crawl anywhere inside your home in search of prey. And your bathroom is no exception.
They can land up in the bathtub or sink while looking for prey. But brown recluse can’t get out from there.
It’s because the spider can’t crawl on a slick and slippery surface.
Signs Of Brown Recluse Infestation
In all honesty, it’s hard to detect signs of brown recluse infestation.
It’s because infestation levels vary from one single to maybe hundreds living inside a home.
Only a licensed and experienced pest controller can accurately gauge how many brown recluses are inside your home.
Here are three signs of brown recluse infestation –
- Egg sacs.
- Molted skin
- Spun web in the hiding places
A female brown recluse spider can lay up to 5 egg sacs in her entire lifespan of 2-4 years.
Each egg sac contains 40-50 eggs. The egg sacs are circular and off-white, with one-third of an inch as its diameter.
The eggs take 2 to 3 weeks to hatch.
Brown recluse spiders molt or shed their skin to grow. They can molt 5-8 times before they turn into an adult.
A baby brown recluse spider takes one year to become an adult. It’s during this one year it molts 5-8 times.
Both of these signs of brown recluse infestation are visible in and around their hiding places.
That’s why it’s tough to spot the signs of infestation.
Brown recluse spiders also spin webs where they hide. But they use the web to relax during the day.
Unlike other spiders, brown recluse spiders don’t spin a web to catch their prey.
Brown recluse spiders hunt in an old fashioned by lurking and pouncing on their prey.
Along with living insects and bugs, brown recluses can also eat dead insects.
How To Get Rid Of Brown Recluse Spiders?
If you want to get rid of brown recluse spiders, it’d be best if you leave it on a pest controller to do it.
There quite a few reasons.
First, it’s hard to get rid of brown recluse spiders by yourself.
They hide in the deepest corners of your home, and they’re sneaky creatures.
Insecticides and foggers do not eliminate these spiders either unless you spray them directly on the spiders.
Both have low residual toxicity, and the spiders walk on tiptoes avoiding contact with the surface.
Second, you might know how big is the infestation.
It’s possible to live in a home with hundreds of brown recluses without ever being bitten or seeing a single one of them.
And third, you can confuse other spiders with the brown recluse, especially when you’re unsure how a brown recluse looks.
But there are a few steps that you can take right away to stop brown recluse spiders and other bugs from entering your home.
Step # 1 – Clean The Clutter Inside Your Home
Clutter is what all types of spiders, including the brown recluse, love.
It provides them enough hiding spaces.
And the first step to making your inhabitable for spiders is to clear the clutter in your home.
Step # 2 – Seal The Gaps And Cracks On Your Home’s Walls
Brown recluse sneak into your home through the tiniest voids on the walls, windows, and doors.
If there are any, seal them.
Look for any gaps on doors and window sills. Seal them too.
It’d be best if you use a silicone-based sealant to caulk the gaps.
Silicone-based sealants are the toughest and can easily last two decades.
Step # 3 – Trim Bushes And Shrubs Touching Your Home’s Walls
Brown recluses can exploit these shrubs and bushes to get inside your home.

Step # 4 – Keep Your Yard Or Garden Clean
An unclean yard can be a home to brown recluse spiders and many invasive and destructive pests like roaches and termites.
Clean the debris, reduce the dampness of the yard by fixing water leakages, and ensure that the firewood pile is dry and free of bugs.
You can also use a plant-safe insecticide spray to kill the bugs in your yard and garden.
Step # 5 – Use Spider Traps
Use spider traps if you’ve got a doubt that there is a brown recluse inside your home.
Keep the spider traps for a night near places where brown recluses hide.
The traps lure the spiders out of hiding.

It’ll stop further incursions by brown recluse spiders to your home.
