Signs of rats and mice in an Olympia home
A noise in the wall can be the house settling. These are the signs our technicians look for to confirm rodents before any traps go down.
Droppings and urine stains
Pellets along walls, behind appliances and in cupboards, plus dark smudges where rodents rub along the same path.
Gnaw marks
Chewed corners on doors, feed bins, wiring and stored boxes in the garage or shop.
Sounds after dark
Running or scratching in the ceiling, walls or under the floor once the house is quiet.
Rodents in daylight
WSU notes that rats or mice seen during the day can mean a heavy infestation.
Why September is rodent month around Olympia
In Interstate Pest Management records for new customers in Thurston, Lewis and Mason counties over the last five years, September brought 16% of the year’s new rat and mouse calls, more than any other month, and September through December brought 41%. Rodent calls never stop entirely: every month brought at least 4% of the year’s total.
WSU’s mice and rats fact sheet names the Norway rat, which nests under buildings and in woodpiles, and the roof rat, which climbs into attics and walls. The Washington State Department of Health says mice can squeeze through openings as small as a quarter of an inch, and asks homeowners to store firewood and lumber at least 12 inches off the ground and away from the house.

What waiting costs

How do I clean up mouse droppings safely?
The Washington State Department of Health says to air the space out for 30 minutes, skip the vacuum and broom, wear gloves, and soak droppings with a solution of 1 part bleach to 9 parts water for 10 minutes before wiping them up.
Does the county handle rats?
Thurston County Public Health publishes rodent and hantavirus guidance but does not describe an inspection or baiting service. Inside city limits, Olympia’s rat control code asks residents to keep garbage covered and store materials off the ground. For a rat in the attic, call us.
Do you seal entry points?
Yes. After the inspection we quote exclusion work for the gaps we find, such as vents, pipe openings, garage door corners and foundation gaps. Exclusion materials carry a 1-year warranty.
Do you remove squirrels or other wildlife?
No, our rodent work covers rats and mice. If something bigger is in the attic, call and we’ll point you to someone who handles it.
