I think that is a myth, propagated by those very same Squirrels, to make you feel guilty!! When you are not looking they are writing books on that subject, so people don't throw them outside on their little butts.
For years we have been relocating Squirrels, always adding subsequent clan members to the same location. I am not giving this another thought. I tell them " stay out of my stuff and I leave you in peace." Works for me. Heh, they are even getting a delicious snack along with the gentle kick out the door. 🥜🍪
