The Exterminator Missed Entry Points: Why This Keeps Happening to Bellingham Homeowners
Paid for pest control in Bellingham and rodents came back? The most common reason is missed entry points. Here’s why generalist companies miss them, what they’re missing, and how to make sure the next company gets it right.

Then the scratching started again. They called back. More traps. Same result. Eventually the homeowner started searching for someone who would actually seal the home, and found their way to us.
The most common reason pest control fails in Bellingham is not inadequate traps or ineffective bait. It’s missed entry points.
Why Generalist Companies Miss Entry Points in Bellingham Homes
Entry point identification in Bellingham’s older housing stock is a specific skill. It requires knowing what pre-1940 construction looks like from the inside of a crawlspace, how a settling sill plate creates a gap at the foundation interface, how original plumbing penetrations in 1920s Columbia bungalows look different from modern pipe seals, how corroded aluminum vent screens in Lettered Streets properties can appear intact from the outside while being completely failed at the frame joint.
A generalist pest company, one that handles ants on Monday, wasps on Tuesday, bed bugs on Wednesday, and rodents on Thursday, spreads its inspection knowledge across fifteen pest types. The technician who inspects your Fairhaven home for roof rats may have done a wasp job that morning and a spider treatment the week before. Their inspection checklist exists. Their entry point knowledge is general, not Bellingham-housing-specific.
The entry points they miss are consistently the same ones:
The gap behind the gas meter. The utility company’s meter is positioned on the exterior wall, and the gas line penetration behind it is often unsealed, but the meter box blocks a direct view and most technicians don’t move it to check.
The corroded crawlspace vent frame joint. The screen itself may appear intact, but the aluminum frame has separated from the foundation block at one corner, a gap of three-quarters of an inch along a six-inch run. Visible with a flashlight from inside the crawlspace. Not visible from outside.
The utility penetration behind the water heater. In older Bellingham homes where the water heater is in a utility closet adjacent to the crawlspace, the supply and drain penetrations through the back wall of the closet are often unsealed, and rarely accessed during a standard inspection.
The eave gap above the master bedroom window. In Fairhaven Victorians with decorative eave brackets, the connection between the bracket and the fascia deteriorates from the inside, the bracket appears solid from the ground but has separated at the mounting point, leaving a gap that a roof rat accesses from the tree canopy.
What a Thorough Entry Point Inspection Looks Like in Bellingham
In a pre-1940 Bellingham home with a full crawlspace, a complete entry point inspection takes 60 to 90 minutes. It includes getting under the house with a high-lumen flashlight, checking every section of the sill plate perimeter, opening the utility penetrations to assess the seal quality, checking every vent screen from the inside, photographing every gap found, and rating each one by severity.
The exterior perimeter walk that most pest technicians do, walking around the outside of the house from a standing position, does not find sill plate gaps, corroded vent frame joints, or the gap behind the gas meter. It finds the obvious stuff. Bellingham’s rodent entry points are usually not the obvious stuff.
What We Do Differently
We do one thing: rodents in Bellingham homes. Every inspection is rodent-specific, Bellingham-housing-specific, and documented. We get into every crawlspace. We check behind the gas meter. We photograph everything we find, and we give you that documentation regardless of whether you proceed with service.
If entry points were missed by a previous company, we’ll find them.
Frequently Asked Questions
How do I know if the pest company that’s coming to my Bellingham home will actually find all the entry points?
Ask directly: “Will you get into the crawlspace during the inspection?” If the answer is no, or if the inspection doesn’t include crawlspace access in a home that has one, the inspection is incomplete for a Norway rat situation. Ask whether they’ll provide a written report with photos of entry points found. A company that does a thorough inspection produces documentation. A company that does a perimeter walk and sets traps produces a verbal summary. For Bellingham’s older housing stock, documentation is the standard of a competent inspection.
The pest company said they sealed entry points but rodents are back. What happened?
Several possibilities: the seal material failed (expanding foam in Bellingham’s climate, or steel wool without a backer), a gap was missed during inspection, or new settling in an older home opened a new gap adjacent to an existing seal. The correct response is to call the company back and request a re-inspection under whatever guarantee they offered. If they don’t offer a return inspection or don’t find what allowed re-entry, a second opinion inspection from a different company is the right step. We perform second-opinion inspections specifically for this situation and frequently find the missed entry points.
