throughout insulation, they chew on wood, they leave behind all kinds of debris and droppings, and worst

It's not just the annoying noise they make while scampering around in your attic, ceiling, walls, etc. They can pose a very real risk. The wire chewing can cause electrical shorts, and is a potential fire hazard. The droppings and urine leave a pheromone smell that attracts new rodents. Once an attic is full of rat poop, it's a magnet for new rats, and sometimes the predators that hunt them as well. The best way to get rid of rodents in the attic is not with poison, but with trapping and removal, then most importantly, the sealing shut of any and all entry points into the building.
