I think how to keep spiders out can be a very common question, especially for those who live in the suburban area. And my suggestion for you would be to keep your home clean and free of clutter. Spiders like to reside in clutter amidst old books, stacks of papers and other items. Clean out the spaces that hold hiding spots for spiders.
You want to vacuum all of the rooms in your house. Touch the hose in the corners and small spaces where spiders could live. Spiders lay eggs, so you want to clean the whole area thoroughly.
Knock the spider webs down. Get a broomstick or fly swatter and go at it. It is a form of stress relief, too. When the spider webs get knocked down, they will probably not return to that spot. After they leave, you can paint over the walls with a strong paint as a preventative measure.
