While rats are most commonly known for their role in spreading the plague throughout Europe, they are likely not spreading the plague in your home, however there are still health risks that come hand in hand with rats in your dwelling. Just like any wild animal, they have the capability to bring many distinct sorts of ailments, insects, and bacteria to your house.
Rats have been known to carry several diseases that can be transferred to humans and other animals. The most common of these diseases is meningitis, but there are approximately 30 other ailments that have also been connected with rats. Most of these are transferred by unknowingly ingesting items that have been touched or eaten off of by the rats. Which makes the idea of them in your kitchen even more terrifying. Since any food that was able to be accessed by the rats could be a host for these diseases, it's important to throw away any food that may have been contaminated. Rats can also spread illnesses through feces, urine, or biting. Additionally, just like how the plague spread, if a flea is on a rat and bites them and then bites you, you are at risk for any diseases that rat may be carrying.
Most rats lived either in sewers or out in the wild before they found your comfy attic, they will likely bring bugs into the home as well. Most commonly, the bugs that come with rats are fleas and ticks. While fleas and ticks love households with pets, they can be a nuisance for you as well. Flea and tick infestations on top of a rodent infestation is no laughing matter and can become very serious.
While not a disease that they spread, rats can also induce high stress situations due to lack of sleep from their noises or from just the idea of them being in your home in general. Stress can make pre-existing conditions worse. If they are chewing on electrical wiring, they could potentially be creating a fire hazard, putting your family at risk.
