What does pregnant spider look like?

A pregnant spider looks like a normal female but with a significantly larger, rounder abdomen (opisthosoma), which swells as her egg sac develops inside; it's often hard to tell if she's "pregnant" or just well-fed until she produces a silk egg sac, which can look like a tiny cotton ball, papery lantern, or disc, or until the babies emerge, like the famous wolf spider carrying hundreds on her back.


How to tell a spider is pregnant?

You can tell a female spider is "pregnant" (carrying eggs) by looking for a large, silk-wrapped egg sac attached to her body or nearby, or by observing her behavior, like guarding a hidden sac or carrying it around (Wolf spiders), which often makes her abdomen look swollen and changes her posture as she guards her future babies.
 

How to tell if a spider has eggs?

Spider eggs are typically housed in silk sacs or cocoons, which can vary in shape and color depending on the species.

How to tell if a spider is female?

To tell if a spider is female, look for a plump abdomen (males are often smaller/thinner) and a distinct, often shiny, structure called the epigynum on the underside of her abdomen near the front; males have bulbous "boxing glove" pedipalps (mouth appendages) used for reproduction, while females have slender ones. These features are clearest in mature spiders, with females generally being larger and having rounder bodies, while males are smaller and more slender.
 


Why shouldn't you squish a spider?

“Squashing a female may release dozens of baby spiders if she's carrying eggs. And squashing spreads pheromones that attract more scavengers.

Many spiders lay eggs multiple times, producing hundreds of thousands of young.


What time of year do spiders have babies?

Spiders have babies (spiderlings) after the female lays eggs in a silk sac, typically in late summer or fall, though it varies by species, with hatching occurring when it's warm enough, often in spring, but sometimes weeks after laying. Mating happens, eggs are fertilized internally, then laid in a sac, and hatch into tiny spiders (spiderlings) that disperse, often via "ballooning," to start their own lives.
 

Should I destroy a spider egg sac?

Yes, you should generally remove spider egg sacs from inside your home to prevent large infestations, especially if you're unsure of the spider's type, as they can contain hundreds of eggs; use a vacuum or broom and dispose of them outside, or for venomous spiders like black widows, spray with a vinegar/water or bleach/water solution first before removal. For beneficial garden spiders, consider moving the sac outdoors or leaving it alone, as most hatchlings won't survive, but for safety indoors, removal is best. 

Where do spiders usually lay eggs?

Spiders lay their eggs in protective silk sacs, often in dark, secluded, and undisturbed locations like corners, attics, basements, behind furniture, in woodpiles, or under leaves and rocks, to shield them from predators and harsh weather. Some spiders, such as wolf spiders, carry their egg sacs with them, while others, like trapdoor spiders, hide them in burrows.
 


What kills spider eggs instantly?

To kill spider eggs instantly, the most effective methods involve physical destruction (vacuuming and immediate disposal) or using strong chemical sprays like oil-based insecticides or a bleach/water mix, which penetrate the water-repellent silk sac to kill the eggs inside, though physical crushing with a damp cloth also works for immediate removal. Boiling water can also kill eggs on contact, notes Pinnacle Pest Control.
