When to Call a Mice Exterminator in San Luis Obispo
Call a mice exterminator in San Luis Obispo as soon as you notice droppings, a musky odor, or scratching in walls — mice you see in the open mean more are hiding, and a 1/4-inch gap is all they need to keep coming. Early trapping plus exclusion is faster and cheaper than waiting for a full infestation.
Droppings in the kitchen
House mouse droppings are about 1/4-inch, rod-shaped, and show up in cabinets, pantries, and along baseboards. Fresh droppings near food mean active traffic — not an old problem.
Musky odor
That stale, musky smell in the pantry or under the sink is a classic house mouse signature. Odor plus droppings means they've settled in, not just passed through.
Noises at night
Light scratching or scampering inside walls and ceilings after dark. Mice are nocturnal and secretive — if you're hearing them, the population is already established.

Mice or Rats? How to Tell in Your SLO Home
It matters because trap size, placement, and strategy all change with the species. Here's how to read the evidence like a pro.
House mouse signs
About half an ounce and 5–7 inches including a nearly hairless tail, with relatively large ears and light brownish-gray fur. Droppings are 1/4-inch rods; gnaw marks are fine and scratchy (about 1/12 inch); the giveaway smell is musky. They slip through 1/4-inch openings, fit under 1/4-inch-tall gaps, climb any rough vertical surface, and jump 12 inches.
Rat signs
Much larger animals with thicker droppings — roof rat droppings run about 1/2 inch and spindle-shaped, Norway rat about 3/4 inch and capsule-shaped. Gnaw marks show clear 1/6-inch tooth marks. Scratching in the attic at night points to roof rats; burrows along the foundation point to Norway rats. See our rat control page if the evidence points that way.
Where they hide
Mice in the Attic and Walls: What the Sounds Mean
Mice reach attics through wall voids, pipe chases, and gaps around wiring — then nest in insulation and travel the same routes nightly. Light, quick scratching high in walls or above ceilings is the signature; heavier thumping or dragging usually means rats.
Inside, mice stick to kitchens, pantries, garages, and anywhere food is stored — traveling along walls and behind appliances rather than crossing open rooms. In SLO's student rentals around Cal Poly, cluttered garages and inconsistent trash routines turn group houses into ideal mouse habitat. Sealing the routes matters more than the room: until wall voids and pipe chases are closed, attic mice just relocate instead of leaving.
How we do it
How We Get Rid of House Mice
UC IPM's playbook, applied to your house: the right trap size, placed where mice actually travel, in numbers most people underestimate — then sealed entries so it sticks.
-
Inspect
We confirm it's mice (not rats), find the droppings trails, and map how they're getting in — because a mouse needs only a 1/4-inch opening, and most homes have several.
-
Trap correctly
Snap traps no more than 10 feet apart in active areas, tight to walls, in dark corners and behind objects — often in pairs an inch or two apart. Mice are curious but cautious around new objects, so placement beats bait.
-
Exclude
Every opening over 1/4 inch sealed with steel wool, galvanized mesh, and door sweeps — materials mice can't chew through. UC IPM calls exclusion the most successful and permanent form of house mouse control.
-
Sanitize the attractants
Pet food picked up at night, pantry goods in sealed containers, garbage tight-lidded. Sanitation has to be ongoing — without it, new mice find the same welcome mat.
Why our way works
Why Trapping + Exclusion Beats Poison for Mice
UC IPM prefers trapping indoors — and for good reason: a poisoned mouse dies inside your walls, and then you have an odor and sanitation problem instead of a mouse problem. Trapping removes the animal where you can dispose of it; exclusion makes sure the next mouse never gets in.
There's a legal angle too. California's rodenticide rules sharply restrict the old anticoagulant poisons for structural use, and it's illegal in California to relocate live-caught house mice without a permit. The compliant, effective path is the same one we'd recommend anyway: inspect, trap properly, seal everything, and keep the attractants under control.
Good to know
Mice Control Questions, Answered
Mice are about 5–7 inches including the tail, weigh roughly half an ounce, have relatively large ears, leave 1/4-inch rod-shaped droppings and a musky odor. Rats are much larger with bigger droppings — roof rat droppings are about 1/2 inch, Norway rat about 3/4 inch.
Most people set too few. UC IPM recommends traps no more than 10 feet apart in active areas, close to walls, in secluded spots, behind objects, in dark corners, and wherever droppings are found. Setting them in pairs an inch or two apart increases success.
Very likely. A musky odor is a classic house mouse sign, along with 1/4-inch rod-shaped droppings, fine scratchy gnaw marks, and activity along baseboards and inside cabinets at night.
Yes. House mice climb any rough vertical surface and can jump 12 inches straight up. They reach attics through wall voids, pipe chases, and gaps around wiring — which is why sealing beats trapping alone.
Seeing mice in the open usually means more are hiding — mice are nocturnal and secretive. A specialist confirms the extent with an inspection; if it's truly minor, we'll tell you that instead of selling you a program.
They will if the entry points stay open — a mouse fits through a 1/4-inch gap. That's why our work pairs trapping with exclusion: remove the current mice, then seal every opening so the next ones can't get in.
