Do Spiders Bite? Identifying & Treating Spider Bites

How many times have you noticed a red bump on your skin and assumed it was a spider bite without knowing where it came from?

Maybe you saw a spider scurrying around recently, so the answer seemed obvious, but that’s not always the case. Almost every home has spiders. Most human-spider contact happens at home with a harmless house spider. Some spiders are dangerous, but most aren’t anything to worry about. Find out how to tell if it actually is a spider bite, and what you should if you’ve been bit by a spider.

Identifying Spider Bites

Spider bites are often blamed for mysterious red bumps or itchy spots on a person’s body, but spiders don’t bite people as often as you may think. Identifying a spider bite is easiest if you see it happen. If you don’t see it happen, you can use other clues to figure out if it is a spider bite.
