Rat? Mouse? in Cellar - Now What?
I can't believe I'm in this situation but, I was getting something in our cellar where we store food, beverages, cleaning products, clothes etc. - and something scurried by me, either a mouse or rat, I'm not sure which. We have owned the house (a brownstone rowhouse, attached on both sides) for almost 7 years and I've never seen anything like that anywhere in the house. Our former top floor tenant had a mouse problem but that was because mice had chewed through the back of his stove from the attached houses - an exterminator closed up the hole and the mouse problem went away.
We are in the middle of a renovation and have workers digging up dirt in our small backyard and setting down cement for a deck, and they opened our cellar's storm door in back and it was open all day and has been open for a couple of nights (the workers left it open and we have never used it before so didn't close it, our mistake) - the inside door to the cellar was closed at night but open during the day. Could whatever I saw have gotten in that way? I've never seen mice or rats in our backyard.
I'm confounded both as to how this thing got into our cellar and what that means in terms of numbers of them, and how we get rid of them. From now on the storm door needs to stay closed as much as possible obviously but this seems like a much bigger problem. I'm probably going to buy rat snap traps since I think a rat trap would catch a mouse because it's bigger. This is an urban location, in a brownstone, tiny backyard, cellar the size of the floor above it.
Any thoughts? Suggestions?
