I'm sure you already know the answer to this question. And, because there are so many different types of businesses, it is hard to specifically describe how these two pests will affect your specific business. Instead, I will cover the general dangers of having mice and rats inside a man made structure, and you can extrapolate how it relates to you.
Mice are known to carry many diseases, but the most deadly is the Hantavirus, which leads to Hantavirus pulmonary syndrome, a potentially fatal disease. The CDC has also concluded that mice and rats can carry any of the following: Hemorrhagic fever with renal syndrome, lass fever, leptospirosis, lymphocytic chorio-meningitis, omsk hemorrhagic fever, plague, rat-bite fever, salmonellosis, tularemia, and many South American arenaviruses.
Because of their foraging habits, mice and rats come in contact with harmful bacteria and spread them to the counters, tables, dishes, silverware, and stored food in your business. These bacteria can produce flu-like symptoms, such as: vomiting, diarrhea, fever, stomach cramps, and dizziness. Rodent illness can do permanent damage to a company whose brand is connected to growing, transporting, storing, or selling food products.
Mice and rats can carry parasites in their fur, like lice, fleas, mites, ticks, etc. If you have rodents in your business, you have the potential for parasite outbreaks. Lice can fall off onto couches, chairs, rugs, and other fabrics and upholstery. If you run a daycare, this can be a significant problem.
Mice and rats chew wood, sheetrock, insulation, food packaging, and wiring. They are both considered a fire hazard, but rats can do significantly more damage to a man-made structure.
You only get one chance to make a first impression. A rat sighting, tainted food, a lice outbreak, a disease epidemic, and such, can damage your companies reputation. Whether it will drive customers, clients, or guests away, depends on the temperament of the person visiting your establishment. But you can make a good first impression by maintaining a rodent-free business.
Don't let mice and rats threaten your business. Partner with a pest management company like McCall Service, and get your property sealed. You've sacrificed too much to allow rodents to ruin your business.
