Be on the lookout for mice. They chewed through cardboard boxes my Dad had stored blankets in. They had babies cozily tucked away in between the folds. Another time we had some rags stored in shed they chewed it up and packed it under the hood of the riding lawn mower That resulted to a trip to the repair shop. If its hot they won't likely be in there but if they stay out there when the temps start to get chilly they might.
