I have had this problem too! I talk to an exsterminator and he said there is no real way to get rid of spiders. He also said to make sure all clutter outside near you house/building is cleaned. Specially the stuff near doors or windows. Get ride of plant debri, leaves, check the headges, etc... Specially the hedges, the spiders love hedges. If they are in the hedges, the best way is to get rid of the hedges. It was the only way we were able to get rid of ours. We had the big black wolf spiders. They also come from under the doors. So you can block out the space from the doors, that will help too! Good luck and God speed! Hope this helps a little!
I spotted a spider web In my room 2 days ago. I've been sleeping in my guest room ever since. How do I find out where it/they are and are there any traps I can set if I can't find them?
