Storing a dollhouse safely?

Hello! Some background info: I have inherited two gorgeous dollhouses from my grandmother. They are both made of wood and have grass and trees on the outside. In their prime, they had working lights in every room and seasonal decor we would switch out together every month. Over the years, they have yellowed and the lights don’t work anymore. Regardless, I am very attached to these dollhouses and would love to restore them someday.

Right now, I have them in a spare bedroom, but we are expecting a baby and that bedroom needs to be turned into a nursery. The dollhouses are definitely not for children, and I need to store them away for a while so we can work on getting ready for our new arrival. It seems like the easiest places to store them would be either in our basement or attic (both unfinished), but I wanted to see what the folks on this sub think. Neither area is temperature controlled. We have dehumidifiers in our basement because when it rains, one corner of the floor gets wet. Across the basement is dry and has never flooded; I store my Christmas decorations and some other things over there. Our attic does get bats every once in a while. The reason I am concerned is because both dollhouses are made of wood and are over 30 years old. Do you think covering them in plastic would keep them safe? Or should I find another solution? Does it matter if they are in a temperature controlled space? I’m a pack rat so I don’t have a lot of closet space, but if I need to make room for them I will.

Thank you in advance for your thoughts!
