measures (such as trapping or baiting) only correct the symptoms (pests), rather than the
underlying issues (e.g., sanitation and pest access). UPM effectiveness will be re-evaluated at
the end of each contract year based on pest activity, increased passenger volumes, increased
square footage, and compliance of higher sanitation standards and updated Rules and
Regulations.
DETAILS
Prior to the implementation of the UPM program in 2013, airport tenants contracted their pest
control services independently, with little information available to the Port by which to
determine the type and magnitude of concerns the tenants faced or what kind of control
methods their contractors were using to address them. Today the UPM program has 100%
enrollment of all Airport Dining and Retail and airline tenants. UPM gives the Port the ability to
track all pest reports and activity at the airport to better manage the needed actions and
oversee pesticide use. UPM is able to work with many airport departments (Airport Dining and
Retail, Port Construction Services, Aviation Maintenance, etc.) to better remediate pest issues
by addressing items that contribute to the problem, such as inadequate sanitation or small
openings that need to be sealed off to prevent pest access. Pest issues are reported to UPM
through a safety hotline. Call-in data are used to assist in identifying problem areas and
monitoring contractor response times. Consequently, the Port has been successful in tracking
and identifying pest hotspot locations by using call-in data combined with pest data collected
by the vendor (e.g., rodent captures, bait consumption, and activity), and what contributing
factors need to be addressed promptly.
In early 2018, it was necessary for the pest contractor to respond to many more emergency call
outs rather than the proactive work they had been doing. By May 2018 it became clear that
one technician per day could not handle all pest management needs and 24/7 coverage was
justified and prudent. With a rise in pest complaints/sightings by the public in early 2018 and
an increase of complaints to King County Public Health and Washington Department of Labor
and Industry it was urgent that the contractor increase resources and technologies
immediately, raising the cost of the contract well past its original scope and budget.
For the areas serviced today, rodent numbers are expected to stabilize then decline under the
higher level of control efforts and the more recently implemented sanitation audits. The
existing level of effort is required to reach greater than 90 percent eradication, our goal to
prevent another population uptick due to the high reproduction rate of rodents. Concurrently
the Port will audit tenant spaces to further improve sanitation and seal off all pest entry points.
Sanitation audits have been added to the scope of the new pest control contract. Tracking call-
in data, pest data, and condition data (collected from sanitation audits and other Port
inspections) will allow the Port to more efficiently allocate resources to eliminate conditions
conducive to pests. The goal is to eventually reduce costs of the UPM program over time even
with additional building square footage over the next 5 years.
