Believe it or not, a rodent problem may be a sign of a break in your sewer lines. Rats live in sewers and can make their way from your city/mainline tie-in to the pipes running behind your walls. An average rat can squeeze through a crack or opening in your sanitary sewer the size of a quarter (about 3/4 inch) and invite themselves to dinner.
Rodents are responsible for the spread of many life-threatening diseases including Plague and Hemorrhagic Fever. Certain diseases can be transmitted simply by breathing in dust that has been contaminated with rat urine or droppings as well as being directly bitten by an infected rodent.
If you have a persistent rodent problem that pest control tactics can’t seem to solve, try getting a video inspection of your sewer system to see if you have any possible entry points for rodents.
