More Rodents Carrying Hantavirus Found

Six more rodents trapped by County Vector Control technicians last week have tested positive for the sometimes-deadly hantavirus, County officials said this week.

The rodents, four Harvest mice and two California Meadow Voles, were trapped in Fairbanks Ranch and northern Escondido near the San Luis Rey River bringing this year’s total to 16 rodents testing positive for hantavirus, a news release stated. In 2010, a total of 21 rodents tested positive for hantavirus.

“Recent rains have created an abundance of food for rodents, which can increase the rodent population,” said County Environmental Health Director Jack Miller. “More rodents can lead to more hantavirus.” People should never sweep up or vacuum rodent droppings and nesting materials. Instead, ventilate closed areas and use wet cleaning methods with a 10 percent bleach solution or other full strength disinfectant. The best way to prevent the disease is to keep mice out of houses, garages and sheds by sealing all holes larger than the size of a dime, the news release stated.

Wild rodents, primarily deer mice, carry hantavirus. People can contract it by inhaling dust particles from rodent droppings and nesting materials that contain the virus. The virus can cause hantavirus pulmonary syndrome (HPS), which begins with flu-like symptoms, but can graduate to severe breathing difficulties and even death, according to the news release. There is no vaccine or specific treatment for hantavirus and the national Centers for Disease Control and Prevention report that HPS has killed 36 percent of all the people known to have contracted the disease.

How to Avoid Exposure:

• Eliminate rodent infestations immediately.
• Avoid rodent infested areas. Do not stir up dust or materials that may be contaminated with feces and urine.
• Clean up rodent droppings and urine using the wet cleaning method described below.

Use “wet-cleaning” methods to prevent inhaling the virus:

• DO NOT SWEEP OR VACUUM INFESTED AREAS.
• Ventilate affected area by opening doors and windows for at least 30 minutes.
• Use rubber gloves. Spray a 10 percent bleach solution (2 tablespoons bleach to 1 cup of water), or other full strength disinfectant onto dead rodents, rodent droppings, nests, contaminated traps, and surrounding areas and let the disinfectant stand for at least 15 minutes before cleaning. Clean with a sponge or a mop.
• Place disinfected rodents and debris into two plastic bags, seal them and discard in the trash.
• Wash gloves in a bleach solution, then soap and water, and dispose of them using the same double-bag method. Thoroughly wash your bare hands with soap and water.

We live in a world where technology is not only king but it is blazing fast. A picture or video can be taken and uploaded to Google or YouTube within minutes and seen by millions of people. What does this mean to your business? This technology should scare the heck out of businesses, especially food handling ones, as it pertains to pest control. Do you remember the fast food chain that became an internet sensation with rats inside the restaurant? The video became an internet sensation. What about the famous cheesecake company that had the mice inside the display case? Another internet sensation video. What about the monstrous fortune 500 chain store that had pictures of mice on inventory? Those pictures were on the front page of a big city newspaper then covered by media outlets nationwide.

Bottom line is EVERYONE has a Blackberry, iPhone, or some type of smart phone. Heck, even iPods do video now! If your establishment has a history of pests then you are at risk for being the next big news story. What would this do to your reputation? It cost the firms above MILLIONS of dollars!!! This could be crippling to a small business. Let’s say it is not as severe as above, what if a customer sees a pest then puts their poor experience review on a website. Experts say that a bad experience may now be told to 232 people on average because of the internet. If you are a restaurant or any business can you afford to lose hundreds of customers in today’s economy? Hopefully this makes you realize how priceless pest management is to your business.
