There is bats in the upstairs of my boyfriends house, theyve owned this house for 20 years and dont think its a problem since they used to sleep upstairs, it needs to be rennovated before they can be turned into rooms again but they want to have a room upstairs for my son when hes born, im not sure when they plan on that and iv been staying here half the time because my bf would rather be here than my apartment, they have picked up the poop thats up there but your not suppose to do it yourself your suppose to have a proffesionall remove it which costs thousands of dollars, they dont think its an issue but i can still hear the bats up there at night and will not allow my son to sleep up there let alone be up there, but since they dont think its a big deal how do i tell them without confilict? I feel like it will offend them and anytime iv said something before i just hear well weve lived here for years and were fine.. but i dont want my son sleeping in a room with guano.. help?
