Spiders have been bad around my house for the past couple of years, but unless they are trying to usurp my chair or bed, I am mostly resigned to their presence, because they eat other insects that can be real pests. Black widows are the only ones I will not tolerate. If your spiders are really unbearable, you can try squirting (food grade, if it matters to you) diatomaceous earth along the edges of the room and other places where spiders might hide. You should also keep after their webs to discourage them.
