Not all brown spiders in homes are big and prominent like the brown recluse spiders.
There are species of tiny brown spiders that sneak and hide inside homes. Although these spiders are harmless, their sudden appearance can be scary for many people.
This guide will reveal small brown spiders common in many homes.
In this guide you’ll find out what are those little spiders, why they sneak inside home, and what are the most common places they hide and spin their webs.
Plus, there are hacks to get rid of these spiders safely and prevent them from coming back.
That’s not all. You’ll also get to know why sightings of certain tiny brown spiders can signify a spider infestation.
Why Are There Tiny Spiders In Your House?
The reasons for the appearance of tiny spiders in your home are four –
- They’ve sneaked inside for food and shelter
- The tiny spiders want to escape the bad weather outdoors
- Mating calls from the spiders that are already in your home
- Spider eggs in your home have hatched
All the above four reasons cause spiders in the home.
And these reasons are not only for the tiny brown spiders you’re noticing now but also for most spider species entering homes.
So, now that you know what draws these little spiders let’s find out the most common tiny brown spider species that enter homes.
5 Types Of Tiny Brown Spiders In Homes
The most common brown spiders that are small and can sneak inside human homes are –
- False widow spider
- Common house spider
- Orb weaver spider
- Cellar spider
- Jumping spider
The jumping spider and the orb weaver spider are accidental intruders to your home. Whereas the other three can easily live in the human habitat without you ever finding them.
Sightings of these little spiders shouldn’t be a cause of concern. It’s because they’re harmless.
However, too many crawling tiny spiders should ring your alarm bells.
Those little spiders can be spiderlings, or spider babies, of big venomous brown spiders like brown recluse spider, wolf spider, and the hobo spider.
You must also not rule out the presence of black widows in your home if you’ve are noticing too many baby spiders.
These spider babies hatch out of the egg sacs and spread all over your home.
Later in the post, you’ll go deeper into the topic.
For now, let’s get into the tiny spiders from the list and find out where they hide and how they get inside.
Steatoda Grossa Or The False Widow Spider
Steatoda Grossa, also known as the false widow spider, got its name because it has the same shape and size as the black widow spider.
But the false widow spider isn’t shiny black like the black widow spider.
It’s brown. However, the shades of brown vary depending on the sex of the false widow spider.
The female false widow spider is blackish brown, whereas the male is reddish brown.
Like in most spider species, the female false widows are bigger than the males.
An adult female false widow is 6-10 mm in size. The adult males grow up to 4-9 mm.
But their shapes are similar to the black widows.
Like the black widow spider, the false widow spider has a bulbous abdomen that is very prominent.
It overshadows the head and the thorax of the false widow. The abdomen of the false widow spider can be blackish with tan random spots on it.
But apart from the color, one more factor distinguishes between the false and black widows.
It’s the red hourglass on the abdomen. The false widow spider doesn’t have it.
The false widow spider is also shiny and has random marks on its abdomen.
Where Do False Widow Spiders In Your Home?
Like all house spiders, the false widow spiders love clutter. They prefer hiding in messy, dusty dark places with less human footfall.
But the false widow has a unique habit of hiding in cabinets, closets, wardrobes, cupboards, behind books on the bookshelves, and even underneath electrical appliances.
That’s why when people are cleaning these places, they get startled by the sudden appearance of this spider.
But the truth is that the false widow spider has been hiding there for quite some time.
The false widow spider is also a solitary spider. It won’t hide in groups in one place.
But the presence of one false widow spider does indicate that there can be more.
After all, if your home can provide shelter to one spider, it can provide the same to many of them.
The American Common House Spiders Or The Cobweb Spiders
No home in America is stranger to the American house spider. Also known as the common house spider, these are like year-long intruders in American homes.
The legs’ colors are pretty distinct from their body colors. They’re brown. However, some American house spiders can also have white and gray patches on their bodies.
They’ve got slender and long legs. The legs, however, have different colors than their bodies.
The common house spiders have yellow and orange stripes on their legs.
The females grow up to 6 mm in size. The males being smaller, grow up to 4 mm. The hairy bristles on their bodies
Where Do The American Common House Spider Hide Inside Homes?
The American house spider spins snarly webs on the corners of windows, ceilings, and in the nooks and corners of cluttered places like attics, garages, and basements.
That’s why they’re also known as cobweb spiders.
These spiders’ webs are designed mostly to catch flying bugs. When the prey is stuck on its webs, the house spider will insert its fangs into the prey and inject the venom.
It leaves the carcass of the prey to consume later. Like the false widow spider, the American house spider also has bad eyesight.
It reaches its prey on the web by following the vibrations the prey creates after it gets stuck on the silk web.
The American common house spider is harmless to humans. And it plays dead if you try to poke it.
However, like most spiders, it can bite if it feels threatened. But the American house spider tries its best to avoid human contact.
The Orb Weaver Spider
The orb weaver spider is a common spider you will come across in many homes.
Have you ever noticed a small brown spider resting quietly on a spun web in the window corners? Yes, that’s the orb weavers.
The most common method to identify these spiders is the web they create.
They make large circular webs like what you see in Halloween decorations.
The web looks like a spoked bicycle wheel and has multiple concentric webs in the same web structure.
Orb weaver spiders are brown or gray. But many orb weavers are also golden and yellow.
They come in a range of colors. Some even are reddish.
These spiders are outdoor spiders. That’s why they’re also known as garden spiders.
Where Do Orb Weaver Spiders Hide Inside Your Home?
But heavy rains or extreme temperatures outdoors can make the orb weaver spiders sneak inside homes.
But they won’t stay inside for long. Most of the time, these spiders will quit your home when outdoor weather becomes normal.
They don’t spin their webs in the corners of walls and ceilings.
They spin their webs on the windows, vents, and places where an opening leads to the outdoors.
That’s their strategy to entrap bugs and flies trying to sneak inside homes through these gaps and openings.
The female orb weavers aren’t tiny. A fully grown, mature adult female grows up to 6 inches in size.
But the males are really small. An adult male orb weaver grows only up to 0.5 to 2 inches (12 to 50 mm) in size.
The Cellar Spiders
You’re no stranger to cellar spiders. Have you ever seen a tiny brown spider with long thin legs and a small brown body hanging on the ceiling?
Yes, that’s the cellar spider.
Many homeowners confuse them with daddy longlegs and harvestman spiders.
But they’re all distinct spider species.
Where Do Cellar Spiders Hide Inside Homes?
Cellar spiders build random clumsy webs in the corners of your home. They hang upside down on the web, patiently waiting for a bug or fly to get stuck on the web.
They’re more prone to make their webs high up on the ceiling.
But they got their name because they build their flimsy and haphazard webs on dark and damp places like cellars, inside the corners of the shelves, underneath sinks, and basements.
An adult female cellar spider grows up to 8 mm (or 5/16 inches) in size, excluding the long legs.
If you include their legs’ length, add 2-3 more inches to their size.
The adult male cellar spider is smaller than the females. The males grow to 1.6 mm (1/16 inches) in size, excluding the legs.
The cellar spiders don’t bother humans and pets at all. They don’t bite humans and pets either. And they’re flimsy and delicate.
The Jumping Spider
Jumping spiders are accidental intruders to your home. Like the orb weaver spider, the jumping spider is also an outdoor spider.
Jumping spiders can accidentally jump inside your home, but they don’t actively seek food and shelter inside human homes.
They can also enter homes by latching onto wooden blocks, packages, potted plants, and even on your clothing.
Jumping spiders got their name from their ability to lurk and pounce on their prey to hunt them.
These are not those species of spiders that trap their prey by spinning cobwebs.
Where Do Jumping Spiders Hide Inside Your Home?
As mentioned, jumping spiders don’t actively seek shelter inside human homes.
However, if they get inside, they’ll hide in places like underneath furniture and appliances.
The cracks on the floor, walls, doors, and windows are also hiding places for jumping spiders.
There are many species of jumping spiders. But the tiny brown jumping spiders grow to 2 mm (0.8 inches) in size.
Their shape varies depending on the shape of their abdomen. Jumping spiders’ abdomen can be circular, oval, or elliptical.
The tiny size makes the jumping spider very hard to spot if they’re inside your home.
Many people come across these tiny jumping spiders when cleaning or repairing their homes.
Jumping spiders are also harmless. And they bite people in the rarest of rare cases.
How To Prevent Tiny Brown Spiders From Getting Inside Homes?
The tiny brown spiders are harmless. And there have been many instances when homeowners didn’t know that these spiders exist inside homes.
These spiders are shy, avoid human contact, and seldom bite.
But suddenly, coming across these spiders inside your home isn’t something you’d like to experience.
So, the best way to deal with these little spiders is to ensure they don’t get inside.
But if you find these little brown spiders, use a vacuum cleaner on them. And dispose of the dust bag away from your property.
That’s the easiest and safest way to get rid of these spiders without even touching them or killing them.
To prevent them from entering your home, ensure that there are no bugs and critters inside your house.
These bugs and pests are food for the spiders, which causes many spiders, including the big brown recluse, to sneak inside your home.
Seal the gaps and cracks on the walls, windows, and doors to prevent their entry.
Keep your house clean and clutter-free. It’s because spiders love messy and dusty places to hide.
Spiders hate the peppermint smell. Spraying peppermint oil spray in your home repels spiders and keeps spiders away.
Also, ensure that the outdoor area, like your yard and garden, is bug-free and does not harbor spiders.
Tiny Brown Baby Spiders
Some tiny brown spiders in the house can be the baby spiders of two big spiders that sneak inside homes and hide – the brown recluse spider and the wolf spider.
The baby spiders, also known as spiderlings, signify one thing. There’s a spider infestation in your home.
Infestation occurs when the spiders can breed and lay eggs inside your home.
And that’s what the wolf spider and the brown recluse can do.
Inside your home, these spiders will mate and lay eggs. Both these spiders can lay hundreds of eggs at a time.
They combine the eggs by forming a silken ball, which is known as the egg sac.
And when these eggs hatch, multiple baby spiders emerge out of the egg sac, spreading everywhere in your house.
In case of a spider infestation, you may see tiny spiders on the bed and in places like dresser drawers and closets.
So, how do you differentiate between tiny brown spiders and the baby spiders of the brown recluse and wolf spider?
In all honesty, it’s tricky to do that.
The baby brown recluse spiders have three sets of two eyes (or six eyes). And they’re all at the frontal portion of their heads.
In contrast, the other spiders on the list have eight eyes.
The wolf spider babies are also tiny and brown. But they’ve got random dark markings all over their bodies.
These markings help the wolf spiders camouflage the debris and vegetation outdoors to hunt their prey.
Getting rid of spider infestation on your own can be tricky as it requires eliminating the hiding spiders and spider eggs.
And venomous spiders like the brown recluses, wolf spiders, and the black widows hide their eggs in cluttered places. That makes it hard to spot those eggs.
On top of that, there can be more of them inside your home.
Hence, hiring professional pest control is a wise choice to eliminate a spider infestation in your home, especially when your home has the brown recluse or the black widow spider.
Also, these spiders are aggressive. And they’ll fiercely defend their egg sacs from any threat.
So, that can lead to painful spider bites.
Brown recluse bites are painful, and they can go undetected for hours until the bite symptoms emerge.
Bites from the brown recluse spiders cause skin necrosis (the cells around the bite wound start to die) which can get complicated if you don’t consult the doctor asap.
On the other hand, black widows and wolf spiders can bite too.
Their bites can cause nausea, vomiting, headache, and many other symptoms, including pain and itching on the bitten portion.
So, if these venomous spiders bite you, always seek medical attention.
The tiny brown spiders that enter homes are harmful and don’t bite.
This guide revealed why they enter homes and the most common hiding places.
However, many people confuse these tiny brown spiders with the babies of venomous spiders like the brown recluse, which also hides inside homes.
This guide explained the differences between the brown spiderlings and the adult tiny brown arachnids.
Getting rid of these little brown spiders isn’t difficult. A vacuum cleaner is enough to scoop them off the surface.
But if you notice baby brown spiders, then it means an infestation. In that case, hiring a pest controller is your best action.
