This is a military installation, not an ordinary town.
McChord Field is an active-duty Air Force installation, part of the combined Joint Base Lewis-McChord along with the Army's Fort Lewis. It is not a residential suburb with its own city government, borough hall or civilian mayor, and we are not going to describe it as an ordinary town the way we would a nearby incorporated city.
The 98438 ZIP is listed in our coverage data, and we take calls associated with that ZIP, but access to most of the base itself is controlled and restricted to military personnel, their families and authorized visitors. What we can offer honestly is a phone line that answers calls from this ZIP and can discuss what service might be possible. We cannot promise unrestricted access to every building on an active installation.
On-base housing and family housing areas.
Military installations like Joint Base Lewis-McChord often include family housing areas, and rodent problems in a house are not fundamentally different because the property sits on a base rather than off it. Mice and rats still look for the same gaps, food sources and shelter regardless of who owns the land. If you live in on-base family housing and are trying to arrange pest control, base housing often has its own maintenance and pest control channels through military housing management. It is worth checking with that office first, since work on a controlled installation may need to go through official channels rather than an outside contractor arriving unannounced.
If you are authorized to bring in an outside provider, or if you live in privatized military housing that allows it, our mouse control and rat control services apply the same way they would at any other address, once access and authorization are worked out.
| Situation | What we can offer | What to check first |
|---|---|---|
| On-base family housing with a pest issue | Phone consultation and service if authorized | Base housing maintenance or pest control office. |
| Privatized military housing off strict base control | Standard inspection and treatment if access allows | Whether your housing provider allows outside contractors. |
| An address just outside the base gate | Standard residential coverage under our normal service | No special authorization typically needed. |
| Uncertain whether an address is on-base or off | Call and we will help sort out what applies | Your exact address and housing situation. |
Not sure this matches what you are seeing? Describe it on the call and we will help you sort it out.
Call (888) 686-4821Addresses near the base but not on it.
Not every address with a 98438 ZIP code is inside the secured base perimeter, and civilian neighborhoods just outside the gate are covered the same way as any other part of our service area, with no special authorization needed. If your address is off-base but shares the ZIP, tell us that clearly when you call so we do not spend time on unnecessary questions about base access.
Vehicles and storage areas near the base.
Civilian neighborhoods and storage yards near the base perimeter see the same kind of vehicle-related rodent activity as anywhere else in our service area. A car parked near brush or a storage facility for several days is an easy target regardless of what is on the other side of a fence line. Our vehicle and car rodent removal service applies the same way here as anywhere else off-base.
What we ask before scheduling.
Because this ZIP includes both a secured installation and civilian-adjacent areas, we ask more questions upfront than usual. That includes whether your address is on-base or off, whether you have base access authority to bring in an outside contractor, and who the point of contact is if base housing management needs to be looped in. This is not us trying to make the process harder, it is simply what an honest answer requires given how this ZIP is actually structured.
