Seeing a spider in the corner of your ceiling can trigger instant discomfort — even if you know most spiders are harmless.

The truth is, many house spiders actually help control other pests like flies, ants, and mosquitoes. Still, understanding which type you’re dealing with matters. A few species require caution, while others are simply unwanted guests.

Below are 10 of the most common house spiders in the United States — how to recognize them, where they hide, and the safest ways to manage them.

• Some are harmless and beneficial
