What You Need To Know About Spider Egg Sacs 

If you see an adult spider in your home, chances are good that there are more where that one came from. Spider eggs and baby spiderlings are also likely present, but more difficult to see. Knowing how to identify and dispose of spider egg sacs will help you take control of the spider population in your home.

The Spider Life Cycle

Spiders develop through a process known as simple metamorphosis. This means that baby spiders look and act very similar to the adults of the species. They are smaller and cannot reproduce, but their basic body structure is the same. The life cycle of a spider consists of egg, nymph, and adult. Spiders lay their eggs in egg sacs. These sacs are made out of woven silk and help to protect the eggs and maintain the right humidity. One female spider can lay up to 3,000 eggs in its lifetime, depending on the species. When the eggs hatch, they are known as spiderlings. These spiderlings are usually small and pale in color.

Identifying Spider Egg Sacs

Spider egg sacs vary greatly in size, shape, and color. Most tend to be cream, brown, or white in color. They may be round, tear drop shaped, or even spiky. One commonality is that egg sacs are generally about as big as the spider that produced it.

Getting Rid of Spider Egg Sacs

Spider egg sacs can be found in a number of places. Some leave them in their webs, some attach them to their body and carry them around, and others will leave them hooked to branches, leaves, or other objects. Disposing of spider egg sacs is much like cleaning away spider webs. The easiest method is with a vacuum cleaner hose. Simply suck up the egg sac, and then throw away the bag or empty the canister into an outside trash. If you do not have a vacuum hose or it is not long enough, you can use a broom. Wrap the broom with an old cloth or cover it with a pillow case, and then lift the egg sac off and dispose of it. Do this with caution, however, because accidentally opening up the egg sac can send dozens of baby spiderlings running in all directions.
