Nick shares the shocking fact that 21 million homes during the winter are infested with rats and confirms that most pests, including rats, continue to grow in size and adapt to the poison we use to kill them. He warns that rat feces, can spread bacteria and contaminate food sources, trigger allergies, and respiratory issues and can spread over 35 different diseases, including Hantavirus and Salmonella.

But should we be afraid of them attacking us? Nick says that while mice do not bite, rats have been known to bite, but explains they are usually found in your home’s walls and attic and not roaming around your open home.
