What is red house spider?

The red house spider (Nesticodes rufipes) is a common species of spider found in homes and buildings throughout the United States and Canada.

These spiders are relatively small, with females reaching about 5-8 mm in size and males being slightly smaller. They have a reddish-brown coloration, with a distinctive red stripe along their back.

Red house spiders construct messy, irregular webs in corners, crevices, and other dark, secluded areas of buildings. They are primarily nocturnal hunters, feeding on small insects and other arthropods that become trapped in their webs.

These spiders are not considered dangerous to humans, as their venom is not potent enough to cause any serious harm. However, they may bite if threatened or handled roughly, which can result in mild irritation and swelling at the site of the bite.

Overall, red house spiders are beneficial creatures to have in and around homes, as they help to control insect populations. Keeping a clean and clutter-free environment can help deter these spiders from taking up residence indoors.
