If baby squirrels are separated from mother in attic how long will she try to get into house?

If baby squirrels are separated from their mother, she may try to access the house for several hours to a few days, searching for them. Squirrel mothers are very protective and will typically return to the nest frequently, especially if they can hear their babies. However, if she is unable to reach them, she may eventually abandon the search. It's important to handle the situation carefully and consider contacting a wildlife rehabilitator for assistance.
