Build your houses without windows yall. The time it takes for their eyes to adjust to the darkness of a nearly pitch black foyer is enough time to make them suffer casualties. Keep furniture on hand that they will have to climb over. Put a good muzzle flash suppressor on your weapon. Keep high powered ammo loaded and dry. Use good magazines and good weapons that you know won't jam up or have failure to eject or feed issues. If they knock on your door, put your dog in her cage and quietly set up your battlefield.
