Seeing house spiders in the winter? Chances are their web is near their food source (other pests). House spiders spin their webs in corners or creases near pest activity in your home.
To reduce spider activity -keep your house clean and pest free. Seal cracks and use window and door screens to prevent spiders from entering your home. Vacuum webs from the corners and creases to ensure adult spiders and eggs are removed.
House spiders are unwanted pests but generally pose no threats to humans.
