Storing household items in pole barn
We have our house up for sale and plan to move into a rental while we build a new home out on our land. The land currently has an old pole barn that we are going to use to store things we don't need in the rental house, rather than moving them twice. It also makes our house less cluttered looking during the open houses etc . . .
We have inspected the around the exterior and interior metal walls and see no openings. We have caulked small screw holes in the roof to prevent rain from coming in. The only opening we can't get to is at the peak of the roof on one side of the pole barn. Birds are getting in and out--we see their droppings. But something else is getting in as well-- there is scat on the ground (it's a dirt floor) that is about 1/4" in diameter and about 1.5" long. Too big for a mouse or rat and not a bird. What could it be, how could it be getting in, and how can we discourage it?
We have put some pieces of plywood on 2x4's on the floor and are stacking boxes on top of that. Blankets etc have gone into those zippered plastic bags or giant ziplocks and then into cardboard boxes. Misc items are in cardboard boxes that have all opneings taped shut. We're thinking we'll put some sort of tarps over the boxes. Do you think our items will be protected from pests? Is there something else you recommend? The expected length of storage is about 6-9 months--well into the winter.
