Tawny Deer Mouse, Marsh Mouse
The Deer mouse can be problematic because it’s high risk (and primary rodent) of carrying the Hantavirus, otherwise known as (HPS) Hantavirus Pulmonary Syndrome. HPS found in the urine, feces, and saliva of infected rodents including deer mice. Inhalation of even a small amount of dust containing tiny viruses can lead to severe viral infections. The Deer mouse can also be a carrier of Lyme disease and can transfer it to humans. The deer mouse goes undetected as they are nocturnal, but their presence can be deadly even if they go unnoticed.
How to get rid of Deer Mice
Seal up holes around your home using steel wool to keep rodents out. Remove potential nesting sites; this includes leaf piles and thick mulch, stop feeding outdoor birds and move outdoor compost away from home. Clean up food and water sources near your house, use tight-fitting lids for compost and garbage inside and outside the home.
Mice burrow for shelter in concealed areas; You’ll find them anywhere from basements to attics. For nesting sites, they will use space between double walls, floor joists, areas under cupboards and small spaces under sinks where they will feel safe and camouflaged. Mice can climb walls and other vertical surfaces and jump up to 30 cm vertically. They are resourceful and impervious, and this can make them quite hard to eliminate the infestation on your own.
How to Identify Deer Mouse
Deer mice have large ears covered in fur and large eyes that are black. Their eyes, ears, and body of a deer mouse are slightly greater than those of the house mouse. The body can measure 3 to 4 inches long and 5 -8 inches total length. They are orangish-yellow brown on their back with a white underbelly resembling that of a white-tailed deer.
Sign of House Mouse Infestation
Mice are nocturnal animals and have an acute sense of hearing making them hard to see. Most often you will notice a spindle-shaped dropping about 6mm in length. Mice can produce 50-60 droppings per night and urinate very frequently throughout their pathways.
Some other signs of house mouse infestation are:
- Chewing on food packaging and damaged food
- Holes chewed through walls and floors to sharpen their teeth; this creates entry ways into the home
- Foul odour coming from in the walls or other hidden areas
- Chewed electrical wire
- Holes in cushions made for nesting material
What does Deer Mouse eat?
The Deer mouse like most other rodents is an omnivore; they will gather and eat insects, as well as eating seeds, fruits, grains fungi, flowers, and nuts. They will eat stache and hoard food for the winter months to remain hidden from threats.
How serious are Deer Mouse
Hantavirus Pulmonary Syndrome: Found in the urine and feces of infected rodents, most often deer mice. Dust inhalation of contaminated air containing these dust particle a primary concern and should always be avoided.
How to protect from HPS?
The easiest way to avoid HPS is to limit your contact with deer mice and their droppings, urine or saliva. They are attracted to an area where they can find food, shelter, and water.
How can I be exposed to HPS?
- Breathing infected dust from droppings or urine
- Being bitten by an infected deer mouse
- Touching any broken skin after contact with contaminated material
Lyme Disease: is caused by a type of bacteria called Borrelia burgdorferi, transferred between mammals (including deer mice, rabbits, white-tailed deer, and humans). Symptoms can vary but usually involves a skin rash and joint pain (arthritis).
How to protect from Lyme Disease?
Avoid areas with leaf litter, wooded areas, high brush. If entering wooded, high brush or similar areas wear long pants, long-sleeved shirt, closed-toe footwear. Light coloured clothing will make finding any ticks on you easier. Check your body all over – if you are with others, check each other since it makes seeing ticks on your back, etc. easier. Check frequently for the presence of ticks, especially if you are leaving the area. Remove any ticks you find immediately. When touching or removing ticks, wear gloves. Always wash your hands afterward.
How can I be exposed to Lyme Disease?
Lyme disease can exist in an area with these three elements must be present in a natural environment.
- Animals infected with Lyme Disease Bacteria
- Ticks that can transmit the bacteria
- Animal hosts such as mice and deer
Deer Mice can reproduce at any time of the year and produce 3-4 litters per year each having 1-9 young per litter. They can become sexually mature after 5-6 weeks and the average gestation period for each litter is 24 days.
