Thanks to all for reply's. I am one of those O C D type of guys and have spent a great deal of time under Trailer sealing off any access point I can fine. Even with that said here in NY when I put it into storage I do put out bait. I use the pvc pipe method of making a T and setting one by each side between the duels. This is something I can keep an eye here at home.
I guess I out thought myself down there thinking by baiting I might be just drawing them into me.
I do remove all food and water and give it a good cleaning when leaving it. Like some said nothing I can do but hope. I have not heard of fresh cab but I will look it up thank you.
