Thought I had a mouse problem. I've had a visual and its a Noway rat (brown rat). Last week I tightened up to restrict food supply (thought it was mice then). Unnscrewed floor under the kitchen sink and cleaned out a rat luxury suite. Blocked up all entrances I could find with spray foam. Today the cat drew blood, but he got away. Had another sighting two hours later. Dog almost got him, but failed. Been sick with flu and today is the day to finally get him. Plan is to do another clean out. Use steel wool instead of spray foam to block holes and set more traps than I think I need since I only know of one, but obviously there could be more. Will trap areas I think he's going plus basement. Any advice on type of trap or other method is appreciated.
