Which Eggs Do Spiders Lay?

Among the spiders that reside outdoors, there are 137 species. These species vary in size, shape, and color. Some are harmless to humans while others can be a health hazard. Some live indoors and others prefer secluded, dark, or dry spaces. Some may even enter your home through window frames or cardboard boxes.

Among the 137 species, there are eight that can survive both inside and outside. Several of these spiders live throughout the year, laying eggs and building nests. Some of them lay thousands of eggs. A few even molt multiple times.

The female spider takes precautions to keep her eggs from being eaten by predators. She will often lay her eggs in a silk sac. She will also create a silken bed or “blanket” around them to protect them from the elements.

There are a number of different types of spider egg sacs. They can be round, oval, or tear drop-shaped. They can be brown, white, or cream. They usually have a small diameter, usually between 3/8 and 1/2 inches. Some of these egg sacs have uncovered portions, though. The surface silk layer usually is dull brown or green.

Some species of spider carry eggs in their mouths and others spin a silk line to hold them together. There are even parasitic wasps that can lay their eggs in a spider egg.

Besides the spiders that live outside, there are 25 species of spiders that live in homes. These include wolf, cellar, and nursery-web spiders. They will hide in corners and under furniture. Some will even enter your house through cracks in walls or used furniture.
