How to Identify Spider Egg Sacks

Updated February 21, 2017

Spiders are nature’s way of keeping down the insect population. The spiders eat insects like mosquitoes and other bugs. However, the spiders do not always remain outside in the garden doing their jobs. Finding a spider’s egg sack in your home can be a little surprising. Most spiders are harmless and do not bite people, but spiders like the black widow and brown recluse are poisonous to humans and animals. Knowing what type of spider eggs they are will help you decide how to deal with them.

  1. Check your house for spider webs or egg sacks. Egg sacks are small pouches that may contain hundreds of tiny eggs. These sacks are covered by a thin layer of silk and attached to a hard surface for support. When the eggs hatch, the tiny spiders will emerge and leave the nest area in search of food.

  2. Look in dark, damp areas such as basements and cellars. Spiders often choose to make their home in isolated areas where their webs will not be disturbed. The egg sacks may be sheltered in an area of the web or left by itself. If the egg sack is in a web, then the mother spider will be close by to keep an eye her young.

  3. Check garden sheds and outdoor structures for webs. Garden spiders are beneficial to the environment as they keep down the garden pests that would otherwise ruin plants.

  4. Exam the webs to identify the type of spider that made the web. Black widow spider’s webs are made haphazardly with no design or pattern and the egg sacks appear as small round sacs attached to the web. The more elaborate webs with designs typically belong to house or garden spiders. Wolf Spiders carry their egg sacks on the underside of their abdomen and when the eggs hatch, the mother carries them on her back for safety.

  5. Tip

    Most house or garden spiders are small, black or brown spiders with or without stripes on the back or legs. Black Widow spiders are small to medium size with shiny black colour on their back and legs and a red hourglass design on their abdomen. The spider’s body is round and bubble-shaped. If you find a spider in you house the easiest way to remove them is to trap them under a cup and slide a piece of paper under the cup to encase the spider. Take it outside and release it into the garden. Remove spider webs and egg sacks with regular vacuuming and cleaning to discourage spiders from living indoors. When a spider’s web is disturbed, they will leave it and move on.
