It has happened to me hundred times to clean every spot in my house but still see spiders and other insects coming out. I believe that a lot of people experience this problem as well.
When it comes to making spiders and other insects stay away from your home, you are recommended to take a spray bottle and put in there a mixture of peppermint oil with water. You should spray all your windows and doors, and every corner of the house. After few days you will notice that spiders and other insects will disappear from your home.
