Female spiders can lay between 2 to 1000 eggs, which usually differs based on species.
These eggs are well protected in an egg sac, which are usually hidden until they hatch into a bunch of baby spiders.
Or in the case of wolf spiders, she keeps the sac (and later the baby wolf spiders) on her back.
Meanwhile, raft spiders put their egg sacs in a little web tend and guard it until the spiderlings disperse.
What Do Baby Spiders Look Like?
Unlike many insects or other small critters, newborn spiders look like tiny versions of their adult form.
Homeowners might have noticed little, tiny black dots crawling in spiral patterns up and down your ceiling or walls.
Since an egg sac usually contains hundreds of eggs, you’ll usually notice a bunch of baby spiders within a small area.
This differs from the mother spiders which tend to be solitary.
Newborn garden spiders often create little web parachutes to disperse on the wind, which isn’t as easy to do indoors.

What Do Baby Spiders Eat?
Baby spiders are born with a yoke sac, similar to birds, fish, reptiles, and other egg-bound embryo-based animals. The yoke sac also serves as a food source for the spider babies immediately after they hatch.
They keep feeding on the yoke sac until they can get other means of feeding aside from the sac. Some spiderlings feed on other small items such as tiny flies and even pollen.
Araneus diadematus baby spiders (and other orb weavers) may begin creating their trademark webs soon after birth to catch food with. Some species (like wolf spiders) actively care for their babies after hatching.

Benefits of Having Baby Spiders Around Your Home
Although they come in great numbers which may seem like they’d be difficult to control, most baby spiders are harmless and have many benefits.
Spiderlings will eventually mature into allies against many insect pests.
Of course, if they make an appearance in your bed at night, it’s time to let them know they’re unwelcome.
Here are some great reasons to keep these little guys around:
#1 – Spiders Feed on Pests
Adult spiders feed on all sorts of pests, such as ants, roaches, mosquitoes, flies, and moths.
When you let them live, the spiders will eventually locate and feed on most of the insects hiding inside your home.
Also, not all spiders build webs, making them more mobile.
Jumping spiders, the misunderstood hobo spider, and wolf spiders will actively hunt for food.
#2 – Spiders Kill Other Spiders
Two or more different species of spiders often can’t coexist, leading to a gladiator-like competition.
This means those orb weaver baby spiders may help eliminate a species you don’t want in your home or garden.
#3 – Spiders May Help Curtail Disease Spread
Spiders find these household pests quite tasty, helping to keep you and your family healthy.
How to Get Rid of Baby Spiders

Here are 3 tried and true methods for when the rate of baby spiders becomes a little too much to bear.

Preventing an Infestation
A house spider female will lay her eggs somewhere there’s plenty of food.
This is especially true of orb weaver spiders which often die in the winter.
By keeping your house clean and free of leaks, you’ll help prevent bug infestations.
These infestations provide an abundance of food for adult spiders and increase the chances of survival for spiderlings.
Regular cleaning will also eliminate a nest of baby spiders before they have a chance to hatch, as well as displacing adult spiders.
It sounds simple, but these little tricks can deter a mother spider with baby spiders in tow from moving in.
