House Mouse

  • According to PestWorld, house mice breed very quickly and can adapt easily to changing conditions. They tell us that a female house mouse can give birth to HALF A DOZEN babies EVERY THREE WEEKS and can produce up to 35 young per year.
  • Mice can also drop up to 25,000 fecal pellets each year, or 70 times each day. 

Diet & Habits

  • Mice prefer to eat cereal and seeds but can eat insects, nuts and fruits. ONCE INSIDE, mice will almost eat any human food they can find. 
  • House mice have “territories” that can range from 4-5 feet. If they have food and water, their territory is complete, and they have a home.
  • They are excellent climbers and can jump up to a foot high!
  • They typically feed at dusk and before dawn.

How To Prevent House Mice

  • Inspect for any torn wires, insulation, and walls for signs of an infestation.
  • Store boxes and containers off the floor to prevent mice from taking over any undisturbed areas.
  • Seal any cracks or crevices.
  • Keep tree branches and other shrubberies well-trimmed.
  • Store firewood at least 20 feet away from the house. 

Norway Rat

  • They are known for their continuous gnawing, which is their way to cause damage to structures. 
  • They reproduce quickly and give birth to roughly 3-6 liters per year.
  • Norway rats are drawn to piles of wood and can bring in various diseases and bring in fleas to a home.

Diet & Habits

  • Norway rats will eat almost anything but prefer meat, fish and cereal.
  • When outdoors, they typically thrive in fields, farmlands, and structures, as well as riverbanks, garbage, woodpiles, and underneath concrete slabs. 
  • Norway rats can fit through holes the size of a QUARTER and occasionally reside in attics or roofs.

How To Prevent Norway Rats

  • Keep firewood stored away from the structure.
  • Remove debris piles.

  • Raccoons are commonly found in forested areas close to a water source, but they also can scurry around in fields, preferably near livestock watering areas. 
  • They can build “dens” in hollow trees, ground burrows, brush piles, barns, etc. 
  • FACT: Raccoons are one of the MAJOR hosts of RABIES across the U.S. 
  • They are known to raid garages and garbage cans left by the street, always searching for food. 

Diet & Habits

  • Racoons are omnivores and will eat both plants and other animals, like fruits, berries, nuts, fish, and frogs (to name a few!).
  • They can live as long as 12 years in the wild.
  • Raccoons are not as active in the winter but can come out occasionally seeking shelter. 

How To Prevent Raccoon Infestations

  • Inspect your home for any broken vents, holes, and uncapped chimneys as they can easily sneak in this way. 
  • Store trash in sealed areas, like a locked shed or outhouse.
  • Use tight, animal-proof lids if your trash can is out in the open.
  • Rid your yard of any woodpiles. 
  • Store firewood at least 20 feet from your house.

Diet & Habits

  • Besides eating nuts, squirrels are omnivores and eat meat and plants.
  • They will bury food to save it for colder months.
  • Squirrels are typically found in tree nests they built from leaves, twigs, and bark.
