Baby spiders in my back door and window sills, please tell me they will leave soon?!?

Your never more than 10 foot from a spider. Your house is a nesting area. Outside I assume. Small cracks? Some were they nested. Now they are hatching. They will probably leave in 5 to 7 days. No you are not a spider carrier. Habitat was ideal for nesting on or near the home. They will hatch and leave most likely. Look to see if you can see were they are coming from. And seal the area with caulk or foam. After they are hatched. So they don't return next year.
