My house was built in the 1950s. Should I expect a crawl space problem?

Not automatically, but it is worth checking. Houses that age almost always have their original vents, and the ground cover underneath is often torn or missing. That lets moisture into the framing, which draws carpenter ants and makes a comfortable spot for rodents. We'll lift the hatch, look around and tell you plainly whether the barrier needs replacing.

Why do I hear rats in the attic when I've never seen one in the yard?

Roof rats travel along branches and utility lines, so they can reach your attic without crossing the ground at all. On Shoreline's tree-heavy streets that is common. We find the entry points at the roofline, seal them, and trap inside. Cutting back branches that touch or overhang the roof helps keep them from coming back.

They're building townhomes down the street. Will that bring pests to my house?

It can. When lots are cleared, the rats and mice living in the brush and old structures have to go somewhere, and the nearest older house with open vents is an easy choice. The best time to seal your crawl space and roofline is before or during nearby construction, not after the rodents have moved in.

How quickly can you get to Shoreline?

Someone will be at your door within 48 hours. Shoreline is 55 min south of Lake Stevens HQ, and you get a text about 30 minutes before the truck arrives. Stinging-insect calls get priority on the schedule.

Is the treatment safe around kids and pets?

Yes. We use products rated for occupied homes and apply them where pests travel, not across your living space. The technician walks you through what goes down and where before anything is treated. If you keep bees, chickens or a vegetable garden, tell us and we work around them.

Pest control in Shoreline, WA

Shoreline filled in fast after World War II, and street after street still holds the ramblers built between the 1940s and the 1960s. Those houses share the same aging weak spots: crawl space vents, settled framing and a vapor barrier that failed long ago. That housing, more than the water, is what drives pest control in Shoreline.

The tree canopy matters too. Big firs and maples line the older blocks and fill ravines like Boeing Creek, and that shade keeps roofs and siding damp. To the west, the Puget Sound bluffs above Richmond Beach add wind-driven rain and steep lots. It is a different job than the newer suburbs east of the lake.

Rodent Control in Shoreline

Roof rats in Shoreline's mature tree canopy

Roof rats climb. On Shoreline's older blocks, the fir and maple branches reach across rooflines and power lines connect one house to the next, so rats travel overhead and enter through gaps at the eaves, roof vents and where the old attic vents have rusted open. Norway rats work the ground level, burrowing along foundations and into crawl space vents with broken screens.

Rodent control in Shoreline has to cover the whole house, top to bottom. We seal every opening a quarter inch and up with hardware cloth, sheet metal, mortar or copper mesh, set tamper-resistant bait stations outside, put snap traps inside and return to check and clear them. Trim branches back from the roof where you can. Listen for scratching overhead at dusk and look for droppings in the attic insulation.

Ant Control in Shoreline

Carpenter ants in older Shoreline framing

Carpenter ants don't eat wood, but they hollow out wood that moisture has already softened. A 70-year-old sill plate over a damp crawl space, a leaky window frame or a shaded wall that never dries out is exactly what they look for. Mature trees in the yard often hold the parent colony, with satellite nests inside the house.

We identify the species first, since the treatment is different for each. For carpenter ants we find and treat the parent nest and the satellites, not just the trail you see in the kitchen. Odorous house ants, the small ones that show up on counters after rain, get baited, not sprayed, so the workers carry it back to the colony. Watch for fine sawdust below baseboards and large winged ants inside in spring.

Crawl Space & Vapor Barrier in Shoreline

Failed vapor barriers under Shoreline's postwar ramblers

Most postwar Shoreline homes sit over a vented crawl space, and whatever plastic was put down decades ago has usually torn, bunched up or been dragged around by rodents and repair crews. Bare soil breathes moisture into the floor framing all winter, which is what feeds carpenter ants and wood rot.

We remove the old barrier and any insulation contaminated by rodents, seal the vents and gaps against rats and mice, then lay a new 6-mil vapor barrier over the ground. With the ground sealed, the framing can dry out and the crawl space stops being a draw for ants and rodents. If you notice a musty smell, cupping floors, or damp insulation drooping from the joists, the crawl space is worth a look.

From the call to the follow-up

Hiring a Shoreline exterminator

Hiring Pure Guard as your Shoreline exterminator usually starts with a question about the crawl space, because on a house this age that is where half the answers are. We get someone out within 48 hours and text about 30 minutes before arrival. The tech inspects the roofline, the foundation and underneath the floor, then treats or seals what the inspection shows. Return visits check traps and stations, and warranty re-treatments are free.

What changes the job here

Postwar ramblers, view homes and new townhomes in Shoreline

The bulk of Shoreline is single-story ramblers and daylight-basement homes from the 1940s through the 1960s on modest lots with big trees. We see original crawl space vents, gaps where plumbing and wiring were added later, and wood siding that has shrunk away from the trim. Innis Arden and Richmond Beach add hillside view homes where the slope pushes water toward the foundation.

New townhomes and apartments are going up around the light rail stations and along Aurora Avenue. Those buildings start tight, but landscaping beds against the foundation give ants an easy start, and neighboring construction can push displaced rodents into the older homes next door.

Across Shoreline

Shoreline neighborhoods and what they deal with

Richmond Beach: Tree-lined streets near the Sound and the bluff mean damp siding and roof edges, which suit carpenter ants and spiders.
Innis Arden: Forested hillside lots with homes from the 1940s onward put tall trees right over rooflines, a common roof rat route.
Echo Lake: Homes around the small lake and close to Aurora see more mosquitoes in summer and rodents moving along the commercial strip.
Richmond Highlands: Ramblers mixed with new townhomes, so older crawl space problems sit next to fresh construction disturbance.
North City: Blocks near Hamlin Park's woods get ants and rodents working in from the park's edge.
Ridgecrest: Dense postwar housing on small lots means rats move easily from one yard to the next unless each house is sealed.

Through the year

The Shoreline pest year, season by season

Spring: Carpenter ant swarmers come out of damp framing and the big trees in the older neighborhoods on the first warm days.
Summer: Yellowjackets nest in the old rockeries and wall voids, and odorous house ants trail inside after the lawn dries out.
Fall: Roof rats move into attics once the rain returns, often through the canopy rather than across the ground.
Winter: Rodents are settled in crawl spaces and attics, and wet weather shows which crawl spaces have lost their vapor barrier.
