How To Safely Remove Spider Eggs In The House In 3 Steps

Spiders will hide their eggs in your house in places that receive little to no light, are cluttered, and have no human footfall. 

Finding spider eggs in the house is a sign of spider infestation.

These egg sacs, containing hundreds of spider eggs, will produce spiderlings that will hide in your home.

So, removing spider eggs in your house is paramount for removing a spider infestation. 

If you don’t, the spiders will mate and lay more eggs. That will cause more spiders in your home.

You’ll find out how to do it in a minute, but before that, let’s find out where spiders hide their eggs.

Spider Eggs On The Walls

Spiders use their gluey saliva and silken webs to hook their eggs on hard surfaces. 

Spiders will make the eggs stick on the walls and the rear side of the furniture. But they choose the thin gaps and cracks on the wall to hide their eggs.

Spiders lay 200-300 eggs at a time. And they enclose the eggs in a silken egg sac. These egg sacs look whitish, and they’re in the shape of tiny ping pong balls.

Some spider species are more likely to hide their eggs in the wall crevices. These are the spiders that don’t spin webs to catch their prey. 

So, black widow spiders and brown recluse spiders are the common house spiders that hide their eggs in the walls. 

Female wolf spiders don’t deposit their egg sacs. They carry it on their abdomen.

So, if they’ve entered your attic or basement, the wolf spiders will bring the egg sacs with them from the outdoors.

Spider Eggs On The Window 

Spider Eggs On Window

Specific spider species can randomly hook their eggs on the windows and the edges of the windows.

Orb weaver spider is a type of spider that does it. So

The spider will stick the egg sacs, or the egg cases, with spider webs on the window and let them remain there until they hatch.

However, that makes it easy for you to spot the spiders in the window and remove them. 

Most of the time, the spider eggs on the window are attached to the window frame or screen. 

Spider Eggs In Cluttered Places

Spiders love dusty and cluttered places. And they have the propensity to lay and hide their eggs in their living areas.

Spiders hide in cluttered places like the attic, basement, storage rooms, and even the storage sections underneath your bed.

That’s why when the spider eggs inside the bed storage section or in cluttered dresser drawers hatch, many people notice tiny spiders on their beds and couches.

Cardboard boxes (spiders’ favorite), old shoes, and abandoned furniture like couches and chairs in the less frequented areas of your house are prime real estate where spiders will hide their eggs.

Also, these places are great food sources for spiders. Many insects and bugs in these areas make it easy for the spiders to hunt.

How Many Eggs Do House Spider Lay?

House spiders lay anywhere between 250-350 eggs at a time. They pack these eggs into a cream-white spherical silken egg sac. 

A female house spider can lay up to 3000-4000 eggs in her lifetime. And if the eggs are not damaged or destroyed, a female spider can produce 4000 spiders.

The baby spiders or the spiderlings undergo multiple molting for a year before they mature into spiders.

Predators hunt and eat many baby spiders. So, a very of them reach adulthood. 

Precautions To Take Before You Get Rid Of Spider Eggs

Before you get into how to get rid of spider eggs, which is essential in eliminating a spider infestation, there are certain precautions you need to take.

If you’ve found one spider egg sac in your home, then the chances are there are more.

And you’ll need to look for the remaining hidden spider eggs in the house. 

For doing that, please wear shoes, gloves, trousers, and a full sleeve shirt. 

It’s because female spiders are fiercely protective of their eggs.

And if you come across spider eggs in places like the attic, basement, and storage room, the spider lurking nearby can bite you.

You’ll also need a torch light to beam into the crevices of walls and floor to look for the eggs. 

How To Get Rid Of Spider Eggs In The House, Safely?

Now that you’re sure where there are spider eggs, it’s time to remove them. 

There are three ways of safely removing spider eggs: a vacuum cleaner, mixture of bleach and water, and using pesticides.

Use Vacuum Cleaner To Remove Spider Eggs

You can use the vacuum cleaner to remove spider eggs, provided you use it tactfully and don’t break the egg sac.

It’s best to use a vacuum cleaner in places where you can use it. 

Using a vacuum cleaner in tight places can break the egg sacs. 

That can lead to the spillover of tiny baby spiders that can spread elsewhere in your home.

In the worst-case scenario, it can also alert the nearby adult spiders that may come out and bite.

And if those spiders are venomous like the black widow spider, it can be risky for you. 

So, use the vacuum cleaner in places like behind the furniture, storage compartments, and boxes.

Dispose of the vacuum dust bag far from your property. Don’t dispose of the dust bag in your home or yard trash bins.

That’ll ensure that no baby spider will break through the vacuum dust bag and enter your home.

Use A Mixture Of Bleach And Water To Neutralize Spider Eggs

If you’ve noticed spider eggs in tight spaces, like inside the thin gaps and cracks, it’ll be best to use a mixture of bleach and warm water.

Take equal amounts of bleach and warm water. Stir the mixture well to form a solution. 

Ensure that bleach doesn’t meet your skin or eyes. Bleach is highly corrosive and will harm your skin and eyes.

Pour the mixture into a spray bottle. And spray it in the crevices where you’ve found spider egg sacs.

The bleach will destroy the eggs in the sac. It’ll also eliminate any baby spiders inside the egg sacs. 

Do not forget to use your vacuum cleaner to remove the dead baby spiders and damaged egg sac.

Pro Tip: Do not use a broom to remove the spider eggs or spider egg sacs. That can break the spider eggs which can cause the new born spiders to spillover into your house

Spider Spray

There are many spider sprays that you can use on the egg sacs to get rid of them. Terro and web out are two reliable spider sprays that do the job flawlessly.

On noticing the spider egg sac, spray the pesticide directly on the egg sac. The damage won’t be instant.

So, you’ll need to wait for 10-15 minutes for the spray to do it’s job.

After 15 minutes, use a vacuum cleaner to remove the neutralized egg sacs.

Always read the precautionary instructions on the labels of the pesticide spray, and follow them, before using them.

How To Prevent Spiders From Leaving Egg Sacs In Your Home?

Once you’ve removed all the spider eggs inside the house, it’s time to ensure that it never happens again.

To do that, you must remove the conditions that allow spiders to sneak inside homes and lay eggs.

Here’s how to do it in three easy steps.

Remove Clutter Inside Your Home

Spiders love clutter. And the first thing you must do is to nullify any chances of spiders hiding inside your home or leaving behind their egg sacs to clear the clutter inside your house.

These are the favorite places for spiders to hide and lay eggs.

Check out the storage sections in your bedroom and closet. Remove the clutter from these places too.

Maintain Cleanliness Both Inside And Outside Your Home

Regularly vacuum cleaning your home and storage places are the keys to keeping spiders away. 

Plus, ensuring there are no bugs in your home is also essential.

Bugs are food for spiders. And if bugs are in your home, they’ll draw the spiders.

Is there any place in your home you’ve neglected for a long time? If yes, then clean those places and remove the clutter from there.

Also, don’t forget to keep your outdoors clean.

If you’ve got a yard or garden, ensure that there’s no organic debris like rotting wood blocks, foliage, and mulch beds.

Organic wastes mixed with dampness draw many bugs. Those bugs, in turn, attract spiders.

So, maintain proper cleanliness in your home’s outdoor areas too.

To deny spiders from entering through the gaps and crevices on the walls, window sills, crawl spaces, and door frames, seal those gaps.

Use Scents That Repel Spiders

Many scents repel spiders. One of them is the smell of peppermint.

You can use peppermint spray in their hiding places to keep spiders away.

Savvy homeowners regularly use peppermint spray in their basement, attic, garage, and storage rooms because these places are favorites for spiders, mice, and many other bugs to hide.
