Hello! Thanks for all the advice about the monster under my RV bed! Now, I'm wondering about the spring break party on my roof. These are not mice, they are bigger, maybe crows, squirrels or raccoons. Sometimes it even sounds like a person. My 5th wheel is parked partly under several trees, that I can't cut back. (I live in it full-time.) I don't mind the noise, I've named whatever's up there Edward, and he's good company late at night. (Also all day.) But is there any harm he could be doing? nesting in the A/C? doing his business in the exhaust fan? renting out rooms? Thanks for any advice!
