SenesTech is a company committed to long-term, innovative solutions to the age-old problems that continue to challenge our economy, putting a strain on daily operations. A particularly persistent challenge is how to manage rats. Rat infestations are costly to various markets and verticals, threatening brand integrity and bottom lines. To date, there hasn’t been an effective solution that yields long-term results. Until now.
The Reality
In order to understand why rat infestations are so challenging to control, it’s helpful to focus on basic biological rat facts. Although rats only live an average of six months, they are able to reproduce at two months. This means it only takes two rats to produce more than 15,000 offspring within a single year1. Traditionally, these staggering numbers have been combated by the use of lethal rodenticides.
Another biological reality that impacts rat control efforts is the fact that rats drink approximately 10% of their body weight every day2, which factors into the ways PMPs bait and deploy rat control products.
Interestingly enough, significant research has demonstrated that rats are smart enough to sense when their population is compromised. Once aware of lower numbers, primarily signaled by a sudden abundance of food sources, the rats will reproduce rapidly to compensate for decreased numbers. Given the facts shared above, it’s no wonder that this phenomenon results in costly and challenging rat rebounds, which have evidenced where lethal rodenticides fall short.
Moreover, because rats are so smart they often demonstrate one of two troubling behaviors: bait aversion and/or bait shyness. Simply put, bait shyness or neophobia refers to a reluctance on the part of the rats to sample a newly introduced food source. Bait shyness is evidenced by rats sampling small amounts of a new food (bait) until they determine it is safe to consume.
Bait aversion, on the other hand, presents when rats avoid a food source altogether after observing ill effects or behavioral change in other rats. When you consider the results of lethal rodenticides, it’s easy to imagine rats approaching this bait shyly at first, and then avoiding it altogether.
The Result
Given the limitations of lethal rodenticides, coupled with the biological realities of rats, it’s no wonder that rat populations can rebound to their original size or larger in a matter of months.
By leveraging a contraceptive product, the reproductive capabilities of both male and female rats are restricted, thereby creating a long-term maintenance solution to rat infestations.
But, what really is rat birth control?
While human birth control is consumed by women monthly in order to prevent pregnancy, rat birth control is also consumed monthly as a method for reducing fertility, but is consumed by both male and female rats. There are no adverse effects when consumed by males or females. Both still continue to attempt to reproduce as if nothing has changed.
Another benefit of rat birth birth control is its non-lethal formulation; rat birth control minimizes secondary exposure and does not pose a risk to non-target species, unlike lethal rodenticides. In other words, this tool is able to effectively reduce rat populations without the unintended environmental consequences that are commonly associated with rodenticides.
A Sound Solution
Based in sound science, SenesTech has developed a revolutionary product focused on a root cause of rat infestations: reproduction. ContraPest is an effective, liquid rat birth control for both male and females that offers an on-going solution to target reproduction.
