Two rats, two different problems.
Two species turn up on Puyallup calls, and telling them apart changes where we look first. Norway rats are heavier, burrow at ground level, and stay close to foundations, woodpiles, sheds and low vegetation. Roof rats are leaner, climb well, and travel along fence lines, overhead branches and cedar siding to reach an attic or a roofline gap.
Norway rats are the ones most often reported along the lower ground near the Puyallup River and the drainage ditches that feed it, where damp soil and ground cover give them easy burrowing conditions. Roof rats show up more in neighborhoods with mature trees and dense landscaping, where branches overhang a roof or siding gives an easy climb.
| Sign | Norway rat | Roof rat |
|---|---|---|
| Movement | Burrows at ground level, stays low | Climbs trees, fences and siding to reach rooflines. |
| Typical location | Foundations, sheds, woodpiles, ditches | Attics, eaves, overhanging branches. |
| Burrow or nest | Ground burrows near structures or brambles | Raised nests in attics, dense shrubs or ivy. |
| Droppings | About 3/4 inch, blunt ends, capsule shaped | About 1/2 inch, pointed ends, often clustered. |
| First step we take | Check foundation, shed and ditch-side gaps | Check roofline, attic vents and overhanging branches. |
We look at droppings, burrow entries, gnaw marks and travel routes on the visit to confirm which one you have before deciding where to place traps and stations.
Where rats travel around Puyallup properties.
Rats follow the path of least resistance between food, water and shelter. A yard that backs onto blackberry brambles, a drainage ditch, or dense hedge cover gives them a protected route straight to a foundation or a shed wall. Compost piles, bird feeders and pet food left outside overnight are common food draws that keep them coming back.
Sheds and detached garages are frequent starting points, since a gap under a shed floor or a torn vent screen is often overlooked compared with the main house. If you have noticed burrow holes near a shed or fence line, our backyard and outdoor rodent control service covers that ground-level work directly.
A rat problem outside almost always starts before anyone hears one inside.
How a rat visit works.
We start with an exterior walk, looking at foundation edges, shed floors, fence lines, ditch banks and rooflines depending on which species the signs point to. Burrow entries, gnaw marks on wood or plastic, and grease trails along regular routes tell us where activity is concentrated.
- We place traps and tamper-resistant stations on the actual travel routes, not just wherever is convenient, based on what the inspection shows.
- We remove or reduce obvious food sources where we can, such as advising on securing compost, feeders and pet food, and flag conditions we cannot change ourselves.
- We seal ground-level and roofline entry points with materials rats cannot chew through, including sheet metal and hardware cloth at vent openings.
- We schedule a follow-up to check catches, confirm sealing is holding and look for any activity we might have missed on the first pass.
If a rat has already gotten into an attic, our attic and crawl space rodent cleanup service covers the cleanup and sanitizing once the animals are removed. For a property with recurring burrow damage to a lawn or garden bed, we treat the burrows as part of the same visit.

Call (888) 686-4821Fall and winter rat pressure.
Puyallup's long wet season pushes rats toward drier shelter for months, not just during a short freeze. A yard that was quiet in summer can see burrow activity pick up once the fall rains start soaking the ground, and rats that were living comfortably outdoors start testing foundations, sheds and crawl space vents for a dry alternative.
If you have had rats before and the activity came back within a season, tell us that history when you call. It changes how thoroughly we check the exterior and which materials we use to close the gap for good, rather than repeating a fix that did not hold.
When to call it an emergency.
Not every rat sighting needs an urgent visit, but some situations do. Rats actively inside living space, gnawing near a stove or furnace, or a burrow that has undermined a foundation edge or deck footing are reasons to say so clearly when you call. The line is open 24/7 and we prioritize those calls against the regular schedule.
