Yes, you can easily control chip monks with rat traps- if only squirrels were so easy. Bait them with raisins and almonds and cover with a box or a tall enough tray so the trap can work under it. This way you won't inadvertently trap a cardinal or robin which kind of breaks my heart. I use the plastic kind from Gemplers that have a nice baiting indentation that holds my bait well.
