Common Types of Rats and Mice in Kennewick, WA

  • Roof Rats: Introduced into the Seattle area in the 1940s, the roof rat population in Washington has exploded in the past 15 years, becoming a real threat to homes. They're historically associated with bubonic plague and spread other diseases like trichinosis, typhus, and jaundice.
  • Norway Rats: They are primarily nocturnal and often enter homes in the fall, hiding in basements, piles of garbage, or crawlspaces. Apart from causing property damage, Norway rats can also spread diseases like plague, cowpox virus, jaundice, and rat-bite fever.
  • Deer Mice: They generally two-toned in appearance with a lighter (often white) underbelly. Most deer mice have a bi-colored tail, can grow to 7 inches in length, and breed year-round, having up to 5 litters yearly (average of 6 mice per litter). They derive their name from how fast they can run and jump. Deer mice are the most common carrier of Hantavirus, a group of viruses spread by rodents that can cause kidney, blood, or respiratory ailments and can sometimes be fatal in humans.
  • House Mice: These are the most common type of mice in Kennewick. They have light-colored bellies and prefer to nest in dark, secluded areas. They can fit through openings as small as a dime, and though they have poor vision and are color-blind, they make up for it with other enhanced senses. House mice can cause significant property damage by chewing through drywall and insulation, sparking electrical fires by gnawing on wires inside homes.

Signs You May Have a Rats and Mice Problem

Rats and mice are nocturnal creatures preferring to stay hidden during the day and rummage for food at night. The faster you identify the infestation signs, the quicker you can call in professionals to protect your family. Here are a few telltale signs to watch out for:

  • Chew marks and holes: Rodents are known to gnaw on everything from baseboards to wires.
  • Musky odor: The urine of rats and mice has a strong ammonia-like smell that grows stronger as the infestation worsens.
  • Scratching noises: Often heard at night when rats and mice are most active. Listen for scratching noises under floorboards, between partition walls, in false ceilings, basements, and lofts.
  • Droppings: Small, dark brown droppings usually found in cabinets, baseboards, and under furniture are a clear sign of rodent presence. Always use gloves and a mask when cleaning up rodent droppings.
  • Tracks: If you notice tiny footprints, especially in places where dust collects quickly, you may have rats and mice in your home. To check for activity, sprinkle flour, talcom powder or china clay, and check the next day for fresh tracks.
  • Odd pet behavior: Dogs and cats can smell rodents, so if your pet is scratching at walls in a particular area of the house, it could be a sign of rodents.

How to Get Rid of Mice and Rats in Kennewick

Rats and mice are intelligent and adapt quickly to avoid common D-I-Y extermination efforts like traps. They hide in areas mostly inaccessible to humans which makes it challenging to eliminate them. Luckily, you can do a few things to get rid of rats and mice in Kennewick.

  • Remove potential nesting sites in your home and yard, such as leaf piles and deep mulch.
  • Seal holes inside and outside your home to keep the rodents out.
  • Use an organic peppermint-based or ammonia-based cleaner to repel rodents with the smell.
  • Keep your food tightly sealed.
  • Clean up food and water sources in and near your house.
