White mouse-2At any time of the year, the house mouse can be a severe pest problem to any homeowner.  House mice can survive and remain indoors for several years without ever having to search for food or water sources outside.  Whereas with Deer Mice, this species is more of a seasonal pest problem for home owners when they tend to enter homes in the fall months and colder weather arrives and causes food sources to deplete. 

House mice tend to live in groups as they are a social animal.  Each pack will occupy its own area that is marked by scent markers.  Of importance for homeowners is that both species of mice will defecate and urinate in their nests and where they travel.  When the nest becomes too rancid from the urine and droppings, they will travel to construct a new nest.   

The House Mouse can feed as many times as 20 times in a single day.  They will eat a wide variety of foods that can include insects, meats, fruits, vegetables, grains and can also include glues and pastes.  Mice have a range of about 10’ to 30’ feet when foraging for food sources.  This is important because unlike rats which have a much further range to forage for food, their range is typically one dimension, whereas mice are multi-direction (up, down and side to side 10’ to 30’ feet in all directions). 

Mouse Inspection Process

If you think you have mice, starting to see droppings in attic, garage, basement or the kitchen, a complete inspection needs to take place.  The inspection if going to look for:

  • Mouse droppings.
  • Possible food and water sources.
  • Conducive conditions.
  • Urine trails along pathways.
  • Complete inspection due to the 3 dimensional range mice will travel when foraging for food.
  • The house mouse has the ability to breed throughout the entire year.
  • The female mouse will produce roughly 3 litters of babies each year that will contain between 3-12 offspring per litter.  This reproductive process continues 5-10 times a year. 
  • From birth to being able to reproduce is approximately 2 months.  At this fast reproductive rate, it is easy to see how large populations can develop in a short period of time. 
  • On average, in just after 48 hours of giving birth to a litter, a female mouse can become pregnant again. 
  • Mice can jump vertically a distance of 12″ from the floor.
  • Mice can survive and thrive in a cold storage environment at temperatures of 10 degrees Celsius.
  • Mice can fit through an opening the size of a dime.
  • Food Poisoning;
  • Hepatitis;
  • Poliomyelitis;
  • Meningitis; and
  • Rabies.
  • Trichinosis;
  • Typhus Fever; and
  • Lyme’s disease.

House Mouse

The adult House Mouse is approximately 4” inches in length and will weigh about 1 ounce.  Their fur will have a grayish to brown coloring.  Their tail is longer when measured from their head and body and has large ears and their eyes are small and positioned close together.

A water source is not essential to the House Mouses’ survival if their food source contains enough moisture content.  They will typically feed on seed and grain products.  Mice eat several small amounts several times a day and will leave behind a trail of urine and fecal matter.

The droppings of a House Mouse are rounded on the ends and are about ¼” inch in length.  The adults can produce anywhere from 30-60 droppings a day depending upon how many times they have feed.

Because the House Mouse is a good climber, this species of mouse can be found entering homes and buildings from upper levels as well as lower levels.  It also has the ability to jump too!

Deer Mouse

The adult Deer Mouse is roughly 5” inches in size and about 1 ounce in weight.  Its fur coloring is a very dull shade of orange and brown.  Different then the House Mouse, its tail is only half the size of its head and body and large ears.

This mouse will feed on items such as nuts, berries and seeds.  This mouse will gather and store large amounts of food supplies in wall voids, shoes, drawers, closets and cabinets.

These droppings have a pointed end and are smaller only measuring ¼” in size. 

This mouse is very active all year long.  However, as the weather gets colder, outdoor numbers will decrease.  They can be found nesting in furniture, cabinets, dresser drawers, basements, attics, between floors, wall voids and even in parked vehicles too!
