Spider egg sacs vary greatly in appearance, depending on the species of spider. They are made out of woven silk and are typically cream or brown in color. Some have a smooth texture, and some may appear fluffy or soft. They also come in a variety of shapes, from round or teardrop shaped to spiky. Even though there are a lot of variations, it is typically true that the egg sac is similar in size to the spider that created it. Larger egg sacs generally mean it was created by a larger species of spider.

Egg sacs can be found in many different places outdoors and indoors. They usually place them in dark, hidden locations where they will be protected from predators. This may include: under leaves, in wood piles, in ground burrows, in closets, amidst storage boxes, and in corners of rooms.

Disposing of Spider Egg Sacs

It is very tempting to want to smash an egg sac after finding it, but this should be avoided. Smashing it may release hundreds of baby spiderlings throughout your home. The best way to get rid of them is to grab a vacuum with a hose and suck the egg sac up. When you are finished, you can seal the bag and dispose of it in an outdoor trash can. Sometimes a vacuum hose may not be long enough. If this is the situation, you can wrap a cloth around a broom and sweep the egg sac down, being careful not to break it open. You can then take it outside in a sealed container and dispose of it.
