Two sexually energetic rats can produce roughly 15,000 “descendants” in only one 12 months, Siegel stated.

“Rats reproduce faster than poisons, traps or any other lethal means alone can eliminate them. Without birth control, their population often rebounds beyond its original level within a few months of using traditional rat control methods alone,” Siegel added.

Though conventional pest management measures get rid of rats rapidly, it solely takes two rats for the inhabitants to develop again to its authentic measurement and even bigger inside months, in response to the corporate’s web site.

However for roof rats, the bait is positioned in a different way to accommodate their distinctive dwelling state of affairs.

“Just this week, ContraPest began selling the Elevate Bait System which is a new EPA approved way to deploy ContraPest above ground.

“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,” in response to the EPA. 

First-generation anticoagulants had been developed earlier than 1970, however as a result of rodents developed resistance, second-generation anticoagulants had been developed starting within the Nineteen Seventies, which may kill after a single evening’s feeding.

This prompted “California [to enact] legislation in January 2021 prohibiting the use of the four major second generation anticoagulant rodenticides under many circumstances,” Siegel defined.

“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.

The corporate registered ContraPest with the EPA in 2016 as a non-lethal rodenticide for Norway and roof rat inhabitants administration in all 50 states.

It really works alone or together with different unhazardous pest management measures, like traps and eradicating meals sources, to scale back rat populations by roughly 90%, Siegel stated.

However conventional methods are nonetheless the first strategies to regulate rat populations, in response to USA At the moment.

“I think in the pest control industry, at least in the U.S., the idea of fertility control, they’ve heard about it, but it’s not widely understood why it’s beneficial,” stated Brandy Pyzyna, vice chairman of analysis and regulatory affairs at SenesTech.

“It does take a lot of education to explain to people why you wouldn’t just kill.”
