The disease carriers: Deer Mice

They seem tiny, though their presence in homes can cause deadly diseases!

I am speaking of deer mice, one of the widely known carriers for Lyme disease and hantavirus.

The deer mouse is a small, native rodent in the family Muridae with an almost worldwide distribution.

The size and color of deer mouse are highly variable. Its body length ranges 2.8–3.9 in (7–10 cm), the tail 2–5.1 in (5–13 cm), and the body weight 0.6–1.2 oz (18–35 g). There are many subspecies of deer mice found in different geographies. The color of the deer mouse is between grayish to reddish brown. It’s body which is dark on the upper side and white on the lower side. The two-colored coat of these mice gives rise to its common name, a reference to a superficial resemblance to the coloration of white-tailed and mule deer.

The deer mouse will find a place to stay in burrows dug in the ground, or in stumps or rotting logs. They also at times nest in buildings. Deer mice are good climbers as they do the same very often in some regions. They are active at night and can feed on a wide range of nuts and seeds, and when this sort of food is abundant it is stored for leaner times because deer mice are active all winter.

Deer mice are a nuisance in forestry. They feed on large quantities of tree seeds and are responsible for the natural regeneration of harvested stands. They are known as the carriers of dangerous diseases such as hantavirus. Hantavirus pulmonary syndrome can develop from inhaling the virus when deer mouse urine or feces is disturbed.

Common deer mice carrying Lyme disease and hantavirus in your home

Posted Thursday, November 13, 2014 10:00 am

The Fall Harvest and colder weather trigger a massive migration — the rather the innocuous deer mouse is moving into homes across Massachusetts and Connecticut.

The deer mouse came to the attention of the public when it was discovered to be the primary reservoir species for hantavirus in the west and/or Lyme disease along the Eastern seaboard. A recent study in British Columbia showed that 30 percent of studied deer mice were positive for Lyme disease, hantavirus and even the bubonic plague.

Hantavirus attacks the lungs and causes Adult Respitory Distress Syndrome (ARDS). Roughly 50 percent of the cases of ARDS have been fatal. ARDS is contained in mice feces and infects its victims when particles of airborne feces get lodged in the lungs. This is why when disposing of mice feces, you should never vacuum the area — use a damp cloth to pick up the feces and then clean the area with bleach.

Deer mice also harbor Lyme disease, which is passed onto humans through bites from ticks. In fact, Deer Ticks are often misunderstood for passing the Lyme disease from deer, when it is, in fact, the tiniest of “deer mice” who are the culprits. The deer mouse is the primary winter host for the deer tick.

Risk of a rare but deadly mouse-borne virus increases in the spring
By Lena H. Sun April 12, 2017
As the weather warms and people turn to spring cleaning and outdoor activities such as camping and hiking, they need to beware of a rare but deadly virus that is spread through mouse droppings and kills up to 40 percent of people who become infected, public health officials said.

The severe respiratory illness is known as hantavirus pulmonary syndrome or HPS. In the United States, most of these cases are spread by deer mice, which live in woodland areas and deserts and are found throughout North America. People get the disease by breathing in hantavirus when dust from rodents’ dried urine, saliva, and droppings is stirred up in the air, which can happen in houses, garages, and cabins, especially while cleaning. People can also get it by touching mouse urine, droppings or nesting materials that contain the virus, and then touch their eyes, nose or mouth.

To keep rodents away from many ineffective control measures are used traditionally. These methods include the use of rat traps which do not work once the mechanical damage is caused to them. Many places are fumigated, which is a most dangerous method of pest control. Glue boards are used that can be dangerous if pets and children are around. Rat poisons are used which are potential of killing the rodents and spreading the deadly diseases.

Effective and eco-friendly measures are necessary to keep these mice in a bay.

Is there such a solution available?

Yes, C Tech Corporation’s CombirepelTM  is the best solution to keep rodents away from human contact.

CombirepelTM  is a low-toxic, non-hazardous and rodent aversive. This product works on the mechanism of repellency. It does not harm or kill the target species but generate fear or trigger temporary discomfort within the pests that keep the pests away from the application.

The unpleasant experience with the product is imprinted within animal’s memory and passed on its progeny.

CombirepelTM  is available in liquid concentrate which can be diluted in paints and can be applied on interior and exterior of homes. The kitchen and pantry can be painted using this product. The laundry area is dreaded with pests as well where this product can be applied.

The product is available in lacquer form which is a direct application. The lacquer can be applied to the furniture and other wooden accessories. It can be applied to already installed wires and cables, polymeric utility pipes and equipment. The product is compatible with most of the surfaces like metal, wood, concrete, polymer, ceramic etc.

The product available in the form of masterbatch can be incorporated into the polymeric applications like wires and cables, pipes, equipment and accessories while they are manufactured.

CombirepelTM triggers a fear response in rodents thus protecting the application. It causes severe temporary distress to the mucous membrane of the rodents due to which the pest stays away from the application. The product triggers an unpleasant reaction in case if the pest tries to gnaw away the application. After encountering the above-mentioned emotions, the animal instinctively perceives it with something it should stay away from and stores this information for future reference. The fact that certain rodents are repelled is mimicked by other rodents as well. Thus, the other rodents too stay away from the applications. The unpleasant experience is imprinted within the animal’s memory and passed on to its progeny.

The product is compliant with RoHS, RoHS2, ISO, APVMA, NEA and REACH and is FIFRA exempted.
