You need to see it to understand it. If you hear animals in the attic get a good bright flash light and go up and have a closer look. It can be just starting and be at a point where you have no damage to speak of yet but it could have been going on for much longer than you think and you just not of heard them until now. They can chew up enough electrical wiring to burn it down.
People always ask me should I wait to hire an electrician until the animals are gone? I tell them to me it is like going to the doctor it is that important that I would hate to tell them sure wait it out lets save you some money and then the house burn down. If you have to have a dozen trips from an electrician while the animal problem is being handled it's worth every cent you have to spend. Always better to be safe than sorry. And it helps you to sleep better knowing a professional is keeping a close eye on things for you.
It comes as shock to everyone who has had animals in the attic once they see or hear what kind of damage the animals have caused. It hurts and comes at the wrong time in peoples lives and if the animal problem is corrected early enough can save you thousands in repairs.
