“Love is in air” if you happen to live in a city infested with rats.After states, like California, restricted toxic rodenticides, some cities are starting to use a more humane way to control the rat population with birth control called ContraPest, the only fertility control for rats approved by the Environmental Protected Agency (EPA). “[ContraPest] is a ‘milk shake’ for rats. It is a liquid formulation that is high in fat, sweet tasting and very attractive to rats, which need to consume approximately 10 percent of their body weight in water each day,” said Ken Siegel, CEO of SenesTech, which is the company that produces ContraPest.
California restricted the use of toxic rodenticides, causing some cities to control the rat population with rat birth control.

Without birth control, their population often rebounds beyond its original level within a few months of using traditional rat control methods alone,” Siegel added.Although traditional pest control measures eliminate rats quickly, it only takes two rats for the population to grow back to its original size or even larger within months, according to the company’s website. Norway rats are the most common rats, but roof rat populations are on the rise in the United States in the last 15 years, Siegel added.

It is easily deployed indoors and above ground with multiple options for mounting in the rafters of barns, granaries, storage, manufacturing facilities, attics, and lofts,” Siegel told Fox News.Chicago, New York, San Francisco, Washington, D.C. and Los Angeles are among the top five cities who made the 2021 “rat pack” list for being the “rattiest” places in the United States, according to a press release from Orkin, a pest control service. ‘FOREVER CHEMICALS’ IN WATER AND PACKAGING CAN RISK HEALTH, EPA SAYS “Most of the rodenticides used today are anticoagulant compounds that interfere with blood clotting and cause death from excessive bleeding. Deaths typically occur between four days and two weeks after rodents begin to feed on the bait,” according to the EPA. First-generation anticoagulants were developed before 1970, but because rodents developed resistance, second-generation anticoagulants were developed beginning in the 1970s, which can kill after a single night’s feeding. The second generation anticoagulants, however, may stay in animal tissues longer than first-generation ones, so they pose greater risks to other animals not targeted who ingest the poison, per the EPA.This prompted “California [to enact] legislation in January 2021 prohibiting the use of the four major second generation anticoagulant rodenticides under many circumstances,” Siegel explained.”Municipalities are strategically deploying ContraPest along with other more traditional methods of rat control in large public parks, gathering spots and in neighborhoods with high rat activity to accelerate results and prevent rebounding activity,” he added.
ContraPest is currently the only EPA approved rat birth control on the market.
