When Fievel Goes West He Leaves a Mess

When Fievel Goes West He leaves a Mess
Why Rat and Mice Feces are Dangerous to your health

Nov. 2020


Fievel was a beloved mouse in a beloved animated movie about a mouse that adventures west, however, in real life when mice and rodents venture out west to our homes it can create specific concerns.


Rodents, such as rats and mice, leave behind fecal matter that can transmit bacteria, contaminate food, cause allergic reactions, and can transmit diseases to humans. As temperatures begin to drop we see an influx of people in our community having to deal with mice or packrats looking to seek warmer accommodations.  These unwelcomed house guests create nests in an effort to find a warm place to shelter for the winter months.  Many times they find access to shelter in garages, sheds, and in basements or attics.  Many folks believe that the extermination of the rodents will be enough to eradicate the problem.  However, if the fecal matter left behind from the rodents is not also remediated you may have additional cause for concern.


Rodent droppings can spread several types of diseases. Including but not limited to:


Rat-Bite Fever - Potentially fatal infectious disease spread by infected rodents and the consumption of food contaminated by rodents.


Salmonellosis- is a type of food poisoning spread by rodent droppings particularly in contaminated food stores.


Bubonic Plague- spread by the bite of an infected rodent flea. Can cause fever, head ache, and painfully inflamed lymph nodes.


Hantavirus- Potentially life threatening disease passed through the inhalation of rat urine, droppings, or saliva.
