What Diseases Do Rodents Carry? A Comprehensive Overview


Rodents are a common sight in urban and rural areas alike. Despite their innocuous appearance, they can harbor numerous illnesses that pose risks to human health. Knowing what diseases rodents carry can help people take preventative measures to protect themselves and their families.

One of the most well-known diseases that rodents can carry is the bubonic plague. This illness stems from a bacterium known as Yersinia pestis, which spreads to humans via the bites of fleas carrying the infection and residing on rodents. Other diseases that rodents can carry include hantavirus, leptospirosis, and salmonellosis. These diseases can be spread through exposure to rodent urine, droppings, or saliva.

It's crucial to acknowledge that not all species of rodents carry diseases, and not all individuals who come into contact with rodents will become sick. However, it is still crucial to take precautions to avoid contact with rodents and exposure to potential diseases. This can include sealing any entry points for rodents in homes or buildings, practicing good hygiene when handling or disposing of rodent droppings, and contacting a pest control professional if a rodent infestation is suspected.

I’d give a 10 star review if I could! We had a great experience with Critter Stop. Everyone I dealt was friendly, professional, and reassuring. Phillip was very helpful and knowledgeable about the work he was doing. He walked me around the entire house to make sure I saw and understood the services he provided. He was also really nice and answered all my questions — he is exactly the type of person that should be interacting with customers.I love the fact that they will come back for up to 1 year after installation if any problems occur — this shows me they stand behind their work.The owner was great too, he personally came to my house and walked me through their offering.

Critter Stop is a fantastic business! Everyone involved is extremely professional and very easy to communicate with. Chisam, the owner, did a great job of explaining the process to get the squirrels out of my attic during the initial free estimate. The exclusion crew who did all of the initial work was fabulous. The crew consisted of Phillip, Nick and Corey who arrived promptly when they said they would. They are happy, positive employees. Everyone is very polite and patient in explaining their work and answering questions. They came back several times to check the traps and finish it off with the fogging. Lester was very good about following up to schedule each trap check with me, and the office staff who took care of the billing was very efficient. Critter Stop is a well run company with honest, trustworthy employees! Thank you to all of you who worked hard to make my attic critter free and for the peace of mind that you guarantee your work. Great to know I can call them if for some reason a squirrel figures out a way to get back in!
