Short answer: usually no. Most house spiders are shy, avoid people, and their bites are rare. When they do bite (typically only if trapped or handled), the symptoms are generally mild, similar to a mosquito bite or a wasp sting. The well-known medically significant species (like black widows) are uncommon indoors and are not the typical “house spiders” you see in corners and basements.

Bottom line: most “house spiders” help by eating other pests and aren’t a threat to your family or pets.
