Boise Woman Creates Interactive Map to Track Rat Sightings Across Treasure Valley
A Boise resident is taking the growing rat problem in the Treasure Valley into her own hands, launching a community-driven website with an interactive map that allows neighbors to anonymously report rat sightings and signs of infestation across the region.
Robin Hadder, a Boise area resident, built the site after noticing the spread of rat-related concerns throughout the valley. The map lets users document sightings of live or dead rats, as well as physical evidence including droppings, burrows, and chewed materials. Hadder said the response was swift after the site went live, with dozens of reports already submitted by neighbors.
A Growing Problem in Ada County
Rat sightings have become an increasingly common topic of concern for residents across the Treasure Valley and Ada County. The issue drew enough attention earlier this year that state lawmakers took up the question of whether rats should be formally classified as a public nuisance during the legislative session, though no legislation ultimately advanced. Community members have described what some called an explosion in the rodent population in recent years, fueling demand for a coordinated local response.
Hadder connected with reporters near one of the newly flagged sighting locations, close to the Hyatt Hidden Lakes Reserve parking lot off McMillan Road in Boise — an area that appeared on the map as a potential hotspot.
The effort comes at a time when Boise and surrounding communities are also grappling with other environmental and public health concerns. Earlier this year, a local volunteer effort pulled more than 3,800 pounds of trash from the Boise River, with organizers noting the cleanup had barely made a dent in what remained — reflecting a broader community focus on keeping the Treasure Valley clean and livable.
Humane Pest Control at the Core
Beyond just tracking rat populations, Hadder is using the platform to advocate for what she describes as more humane and environmentally responsible pest control methods. Her primary push is to move away from traditional rodenticides — rat poisons — in favor of rodent birth control products that reduce reproduction rather than kill animals outright.
Her concern is not only for rats, but for the broader ecological impact of poison-based control. A recent report of a Treasure Valley family’s cat dying after contact with rat poison added urgency to her message. “Stories like that — I don’t want to hear stories like that anymore,” Hadder said.
She argues that rodent birth control offers a longer-term solution: since rats typically live only one to two years, limiting their ability to reproduce could allow natural die-off to substantially reduce local populations over time without the collateral risks posed by toxic bait stations.
Building a Network of Partners and Data
Hadder is actively recruiting pest control companies to join the project as preferred partners, with the condition that participating exterminators commit to using birth control-based methods rather than poison. Businesses that sign on would be listed on the website as recommended providers for Treasure Valley residents looking for humane options.
The map also has a longer-term scientific purpose. Hadder said she intends to share the location data and results of any pilot programs — including potential rodent birth control trials in identified hotspot areas — openly with the City of Boise and local universities. She envisions the platform as a resource not just for homeowners, but for researchers and public health officials tracking infestation patterns across the region.
“When we find hotspots in towns, we’ll be able to do things like run a trial of rat birth control in an area and document the results,” Hadder said, adding that all findings would be made freely available.
How Ada County Residents Can Get Involved
Boise-area residents who have spotted rats, found burrows, or noticed other signs of infestation are encouraged to submit a report through the interactive map on Hadder’s website. The reporting process is anonymous. Pest control companies interested in becoming listed preferred partners can also reach out through the site.
For homeowners dealing with rat problems near outdoor spaces, trails, or waterways, staying alert to environmental conditions in the area can help. With unsettled weather forecast for the Boise area over Memorial Day weekend, residents spending time outdoors may want to keep an eye out for rodent activity near storm drainage areas and green spaces where rat populations tend to concentrate.
