A tale of two cities

Washington, D.C. and San Francisco, CA. Two metropolitan cities on opposite corners of the contiguous United States. The list in how they differ is long, but they share a story of ContraPest® success. With both cities struggling to control rodent population outbreaks, public health and quality of life became a priority for these areas.

After carefully crafting fertility control additions to each municipality’s integrated pest management programs (IPM), the numbers became clear: ContraPest works when it comes to the city.

Washington, D.C. results:

  • 94-99% reduction in rat sightings, depending on location

San Francisco results:

“When I spoke to people about the possibility of birth control for rats they laughed, but I researched and found [that] that’s exactly what the big cities are doing.”


“ContraPest brought our rodent population way down and we rarely see any evidence of them.”


“After using ContraPest, I observed a quick decrease in the rat population on-site. Six months later, still no sightings. I feel confident using ContraPest because it’s safe. I’m very happy about the security of the bait stations.”
