Are Rodents Dangerous?

Rodents will not only contaminate your food and surfaces, but they are known to spread bacteria and diseases including Hantavirus, Salmonellosis, Rat-Bite Fever, and bubonic plague.

Rodents also love to chew. “Why?” Because their teeth never stop growing. They’ll chew anything they come into contact with, including your personal belongings, pipes, and wires. Not only will their destructive habit of chewing cause thousands of dollars in damage to your home, but it can also lead to house fires. In fact, it’s estimated about 25% of house fires with unknown causes are due to rodent damage.
