Identifying spiders can be fairly simple if you know what to look for. Although for some people finding a spider isn't always a pleasant experience, they are still found in almost every home. With thousands of different varieties of spiders,classified into over a hundred different types of families identifying them by their eggs may seem a little overwhelming especially when there can be four to 600 eggs in a single sac. However, here are a couple of hints and tips to look for when trying to identify a particular spider.

Instructions

  1. 1

    Know your area. Doing a little research on common spiders in your geographical area can help significantly reduce the type of spiders. Some spiders are more common due to factors like climate and environment. It helps to take some notes of the most common spiders in your area. This doesn't have to take a lot of time, it's more a reference for you to help in your search.

  2. 2

    Locate the spider web. Noting the shape and appearance of the web can help identify what type of spider it is. Many spiders have their own unique web designs, which might help narrow your search.

  3. 3

    Once the web is located, look around for any signs of an egg sac. Some spiders carry their eggs sacs on their lower abdomen; others leave the egg sacs entwined in the web. The egg sacs are wrapped in a silk-like texture and can vary in colour from a pearly white to green. If possible, take a picture of the spider. Documenting the spider will help comparing the photos to other spiders and you can go back and reference the photo at any time.

  4. 4

    Observe the size and shape of the egg sac. Egg sacs come in all shapes, sizes and colours, although the majority of egg sacs are round. For example, the common household spider, or garden spider, has egg sacs that are spherical and narrowed at one end and covered with a tough brown, paper-like silk.

  5. 5

    Eggs sacs can be found in places other than on the web or spider. Finding the exact location of the egg sac can be a helpful guide. A trapdoor spider, for example, will leave the egg sac inside a burrow. Two-tailed spiders will have their egg sacs suspended on a long line. One of the most common spiders found around the house and garden is the daddy-long-legs spider. These spiders carry the egg sacs in their jaws. Some species of spiders abandon their eggs and leave them protected in the leaves.

Tips and warnings

  • If you think you have a spider infestation, consult a local pest control company to resolve the issue.
  • Do not touch the spider web or egg sac. Many times the mother is close by and will try to defend her eggs if she senses danger.
