I have an infestation of Flying Squirrels. I've blocked what I believe to be all the possible entrances, except one. I know the entrance is used as they chewed through some expanding foam at the site. I set up a one-way door contraption that leads to a cage. Got up this morning -- no squirrels in the cage.

Does anyone know if their are nights when they don't leave or know if the one way door made them not attempt to leave?
