Get rid of rapidly breeding rodents with a rat repellent

If you see one rat at the farm, rest assured there are many more.

Once a woman begins reproducing, she can have 15,000 offspring within her one-year lifespan. Rats reproduce faster than lethal means can eliminate them.

SenesTech, an Arizona company, has developed a new solution – rat birth control – that will prevent the rodents from ever having grandchildren.

Ken Siegel, CEO of SenesTech, says its EPA-registered rat contraceptive, ContraPest, is “like a rat milkshake.”

“It’s a liquid product, it’s very tasty. Rats really love it. It’s put in a conventional bait station that only rats can access. They drink it and both male and female rats become infertile, an effect that lasts 50 years lasts up to 70 days,” says Siegel. “A rat actually lives about a year, but as long as it continues to consume it, this effect will remain for the rest of its life.”

A natural die-off

When using the “rat milkshake” for the first time in a situation, remember that the rodents will not all be the same age. The half-life of a rat population is about six months.

“You will see the reduction in two to three months. But where you really see it slowing down is when deaths significantly outnumber births,” Siegel says.

During its testing phase over the past five years, the contraceptive has reduced rat populations in a variety of urban and rural settings.

For example, ContraPest was used on a pullet farm in Florida for 12 months. When combined with the farm’s existing pest control program, Siegel said the number of young rats was reduced by nearly 100% and pullet survival improved by 88%. The economic impact was also significant.

He says the pullet farm increased profits by $600,000 because the chicks had fewer predators, less grain consumption and contamination, and less damage to infrastructure on the farm.

Accelerate the rat demise

Rat reduction is accelerated by combining ContraPest with traditional pest control methods that help with the initial knockdown.

“You can use your poisons, you can use traps, you can use fumigants, all the various other parts,” Siegel says. “They also need to focus on exclusion, waste management, etc., and then ContraPest will take those results and improve them dramatically. The key difference is that once the population goes down, as long as you keep using ContraPest, the population won’t come back. You can eventually wean yourself off the more toxic solutions.”

ContraPest is EPA approved and available in all 50 states. It is non-toxic and non-lethal and will not harm other animals, pets or humans.
