The only way to control spiders in or around your house is to eliminate the places they live and their food source. Try vaccuming or sweeping away any webs you find. Clean up all woodpiles, rocks, trash, compost piles, old boards, and other debris. When working in the garden, remember to plant trees and shrubs far enough from the foundation to prohibit movement into the house from the plants, and to allow wind and sun to penetrate. Wear gloves when working in areas that spiders are likely to live, including stacks of firewood, boxes or lumber that have been relatively undisturbed.
Spiders get into the house do so through cracks and crevices.
Screening on all of your windows, properly fitting window frames and caulking in any cracks in the structure of the house will help. If you have fruitflies, consider storing ripe fruit in the refrigerator. Check your potted plants for rotting leaf debris and remove any you find. If you have living spiders in your living space, they must be finding something to eat. Eliminate their food source and they will go elsewhere searching for food.
