The biggest issues here are the last two, plumbing damage, and wire shorting. The most serious problem which can arise from these issues is fires. The reason rats are attracted to things such as wires, in particular, is unknown but it is safe to say that its related to their gnawing nature. As a result, you should always check every important wire in your attic and the rest of your dwelling once you have discovered a rat or an infestation, and replace all compromised wires to prevent things such as fires. As well as all this, the presence of rats in your property, in the attic particularly, will result in everything in the attic being contaminated with feces and urine, forcing you to pretty much throw out everything that’s in there including any insulation you may have.

Due to all this, if you think you may have rats anywhere on your property and in particular your attic, don’t just forget about it or hope it’s not happening out of fear or disgust. You should get on top of it immediately for your own health and safety and to mitigate the damage being done to your property. If you do think there is a rat problem in your attic, take the appropriate steps right away and possibly think about contacting a professional for help. You should never approach a serious rat problem if you do not have the necessary experience and knowledge as there are a number of dangers and health risks associated with the removal of these rodents.
