answer:If you’ve got that many squirrels in the attic, then you’ll soon have that many in the walls and eventually in the kitchen. What you absolutely must do is find their entrance into the attic and seal that off. And if you do that before you evacuate the attic completely, then those squirrels will become desperate for food and water and work their way into the house sooner than they might have otherwise. Either that, or they’ll die horribly and slowly. If you can manage it, sealing off all of the opening/s during the daylight after all of the animals have left for the day to feed might work to simply keep them from returning.
