Mice

Best way to get rid of mice in Seattle, Olympia, Bremerton, Tacoma & Puyallup.

Mice are a problem throughout this state. Although they used to be found more often in older homes and businesses, they have now become well established virtually everywhere. The most common small rodent that infests homes and businesses is the House mouse (Mus musculus).

Frequently Asked Questions About Mice

Why Should I Be Concerned About Mice? Are They Dangerous?

Generally, mice will avoid direct contact with people (bites are rare), but the feces and urine of mice can pose serious health risks. Mice are filth associated and transmit disease. Mice can damage wiring, start fires, and consume large quantities of pet, bird, or livestock food. They also can spoil and contaminate human food. Deer mice (Peromyscus maniculatus), which are common locally in rural and some suburban areas can transmit the deadly Hanta Virus.

What Attracts Mice?

Mice are attracted to a readily available food source and a comfortable place to nest. Many structures have gaps in the foundation that permit entry into or under the building. Common entry points in buildings are gaps in the foundation or around pipes that enter into the structure. Mice also get into buildings through missing or poor-fitting crawl space access doors, vent screens, and gaps under garage doors. A mouse can enter through gaps as little as one-quarter of an inch.

How Will I Know If I Have A Problem With Mice?

Mice are rarely seen since they are most active at night. Some people hear scratching or scurrying sounds at night in their walls or attic. Others might open a cabinet or drawer to discover evidence of gnawing or a cache of food. But, the most common clue is finding mouse droppings (feces). Their droppings are 1/8″ to 1/4″ long and with pointed ends. If you find significantly larger droppings, it may be a rat problem instead of a mouse problem.

Can’t I Just Put Some Poison Bait out (such as D-CON)?

Avoid easy, seemingly quick fixes to a mouse invasion! Quick fixes can have serious consequences that can quickly turn into bad fixes. One common quick fix is to immediately put poison bait out everywhere (i.e. D-con). Mice that die from bait can die inside crawl spaces, attics or walls and produce terrible odors for weeks as they decompose. A fly problem can also ensue from maggots that consume the carcasses. The antiquated idea that mice eat the poison and then leave the area in search of water is false. Even if that were true, in our climate there are likely water sources underneath or around the building that they could use anyway. In addition, many people are unaware that D-Con is one of the most toxic anti-coagulant rodent poisons on the market today. Pets, especially dogs are more susceptible to accidental sickness and death via D-Con than the professional material and application techniques that Whitworth Pest Solutions uses.

The Other Pest Control Company I Called Says They Only Need One Visit To Solve My Problem. They’re A Lot Cheaper Than Whitworth. Why Shouldn’t I Use Them Over You?

Usually the companies that promise quick fixes will put poison bait out everywhere (outside and inside), and you will have to deal with the dead rodent bodies and odor yourself (see above). Whitworth Pest Solutions offers the best way to get ride of mice in Seattle as we will only place rodent bait outside in anchored and protected bait stations in accordance with Washington State law. And we will only place bait outside as a population control measure – not as the sole method to eliminate a complicated existing infestation

How Can I Make My Home or Business Less Vulnerable To Mice Infestation?

Check the building for possible entry points and plug up or repair any problem areas. Any gap of ¼” or more, such as around crawl space access doors or under entry and garage doors may allow mice to enter.

  • Don’t leave pet food outside where mice have easy access to it.
  • At a minimum, clean up birdseed spills which can attract mice. At times we’ll recommend complete stoppage of all bird feeding, at least for a period of time.
  • Use trash cans with tight-fitting lids, and empty them regularly.
  • Do not feed wild animals like squirrels, raccoons or opossums.
What Should I Do If I Think My Home Or Business Is Infested With Mice?

There’s more to rodent control than you might think. Before you attempt to handle the problem, ask yourself these questions:

  • Do I know the species and habits of the rodents to be eliminated? Is it House mice, Deer mice, Norway rats, Roof rats, etc.?
  • Do I know where every entry point is?
  • Do I know the best techniques to use to eradicate them?
  • Do I know where to place traps to attract rodents, but not endanger pets and children or create odors from them dying in the building?

If you can’t answer “yes” to all these questions, then call on us. We’ll do the job right.

Here’s how we’ll remove mice from your home:

On the initial visit we’ll do an exterior inspection of the structure to check for areas where mice might enter. We’ll also note any conditions that may be conducive to worsening the infestation. We’ll draw a diagram of the building and document our findings, providing you with a copy.

Mouse cleanout service

If there are access points or other conditions conducive to an infestation, it is imperative that these are fixed A.S.A.P. or mice problems may continue indefinitely. We also provide mice exclusion and cleanout services, so let us know if you’d like an estimate for repairing any access points or cleaning the crawl space of mice urine and fecal material.

We’ll set snap traps in the areas in which evidence of mice are found. Usually this includes the attic and crawlspace, but may also include the garage, outbuildings, etc.

After the initial visit, there are three follow-ups. Two occur on a weekly basis. The last one occurs two weeks after the 2nd follow-up. Here’s an example:

  • Initial visit occurs January 3rd.
  • First follow-up occurs January 10th.
  • Second follow-up occurs January 17th.
  • Last follow-up occurs January 31st.

At each follow-up visit, traps will be checked, dead mice removed, and traps will be re-baited with lure specially formulated for mice. If you’re having concerns in between scheduled visits, please feel free to contact us. If traps catch mice in between regular visits, we’ll perform an extra service to pick them up at no charge. On the last follow-up we pick up the traps.

After trapping is completed, a continual monthly service or every other month service is recommended for continual control and an ongoing warranty. Without regular service visits, mice will continually attempt to re-enter the building. Rodent bait stations will be placed around the exterior of the building for continual rodent population control. The building will also be covered and under warranty for a variety of other pests in addition to mice, including serious wood destroying organisms found in our state. The pests covered depend on the type of regular service you select.
