For example, if you find something that is the size of a soccer ball, then this is not likely to be a spider egg sac. However, if you find something the size of a dime, then there is a good chance that it is a spider egg sac. A spider egg sac will be about as big as the spider that made it. [4] X Research source For example, if you have spiders in your area that are about the size of golf balls, then the spider egg sacs may be about the same size. Keep in mind that some spiders make just one egg sac, while others make several small ones.
Observe the color to determine if what you are looking at might be a spider egg sac. For example, if the color of the sac is pink or black, then it is probably not a spider egg sac.
Some species of spider lay their eggs in sacs that are on the ground, so there might not always be visible webbing.
If you see any small, pale-colored spiders crawling around what you think might be an egg sac, then it probably is one.
Orbs. Circular patterned webs. Cobwebs or tangle. Messy looking fluffy webs that often appear in the corners of ceilings. Funnels. Webs in the shape of a tunnel that are located in low-traffic areas. Sheet webs. Flat sheet-like or bowl-shaped webs. Wooly webs. Slightly sticky webs with an indistinct shape.
For example, tarantulas often live in burrows in the ground with a thin web covering the opening, disc web spiders often make their small grey webs on tree bark and brick walls, and comb footed spiders often make their webs in houseplants. [12] X Research source
If you do find the spider that made the egg sac you are trying to identify, getting a good look at the spider is your best chance at getting an accurate identification. [14] X Research source
Try to notice the details. For example, if the spider is brown, what shade of brown is it? Does it have any other markings? Is it the same shade of brown over her entire body?
For example, does this spider have hairs that are visible from a distance, like the Bold Jumping Spider, or are the hairs practically invisible even up close, like the hairs on a Brown Recluse?
Try to be objective. Is the spider the size of a pencil eraser? A quarter? A golf ball? Your fist? Most species of spiders have an average size range in inches or centimeters. Try to estimate its size in inches or centimeters to help you as you try to identify it.
