What is grey house spider?

The grey house spider, also known as the common house spider, is a species of spider that is commonly found in and around homes in North America. They are small to medium-sized spiders, typically ranging from 4 to 9 mm in size.

Grey house spiders are typically grey or brown in color, with a mottled or chevron pattern on their abdomen. They have eight legs and two body segments, with two rows of eight eyes on their cephalothorax.

These spiders are known for their webs, which are irregular in shape and often found in corners, crawl spaces, and other secluded areas of the home. They primarily feed on insects and other small arthropods that get caught in their webs.

Grey house spiders are generally harmless to humans, as their venom is not toxic and they are not aggressive. However, they may bite if provoked or threatened, which can cause mild irritation or redness at the site of the bite.

Overall, grey house spiders play an important role in controlling insect populations in and around homes, making them beneficial to have around.
