## Description

Evolve Rat Birth Control Soft Bait Sausages – 1.5 lbs | Scientifically Proven Rat Population Control | Not a Poison, Eco-Conscious, Long-Term Population Management

Review: Only part of the solution - Oh, rats! This isn't the perfect solution to my rat problem, but it will help some. I read the product page carefully, wanting to understand what it was I was buying. When I got it, I was disturbed by the fact that there was information on the product package that I wish had been shown in the picture on the product page. There were many cautions about use and exposure to the skin and eyes. I am almost afraid to touch this stuff, even though the ingredients seem to be fairly innocuous. I smell a rat! I like that this is not poison. I am always concerned about poison having effect beyond the intended target; for example: Insects eating a poisoned corpse, or natural predators like owls and hawks eating a rat that has been poisoned. I did some research to see how this works and found that the cottonseed oil disrupts sperm production in males and blocks egg viability in females. That sounds simple enough and there were reassurances that it does not apply to other animals. However, it is important to note that this means that the birth control is only a temporary thing; It only works while the cotton seed oil is in their system. If you stop using the bait, fertility will return after about 6 weeks. Rats must consume the bait regularly for it to work. If the only thing you are doing is using birth control for rats, it will be a very expensive adventure, especially if the little sausages attract more rats. It could be a never ending problem. Welcome to the rat race! However, I am hopeful for the way that I am doing it. I'm trying to eliminate the rats in my garage. I have sealed off the outside entrances and I am using the birth control inside the garage to eliminate any that have built nests inside the garage cracks in the wall. I have also put up some traps, including one that will electrocute quickly. If these things don't work I'm going to be crying like a rat eating onions. Rat on!
Review: A non-lethal way of managing a rat population - We have a rat issue in our neighborhood (they eat my tomatoes and my neighbors large vegetable garden). I do not want to use poisons, and snap traps haven't been effective. It took a few weeks for the rats in our garden to start taking the bait, but once they started, they will empty the station within 2 days. We just started using this product this year - I am hopeful that this will decrease the population over time (I have seen fewer at night - and so far they haven't found my tomatoes - but too early to tell if it will totally save my vegetables). I will say, the larger bag ziplock works - the smaller bags, I have found the zip didn't function and I had to use a rubber band to reclose the bag.

## Features

- WHAT’S INCLUDED: 1.5 lbs (approx. 21 pieces), EVOLVE Rat Birth Control soft bait sausages
- EFFECTIVE LONG-TERM CONTROL: According to Oklahoma State University Extension, a pair of rats can produce 15,000 offspring in one year. Scientifically proven by SenesTech’s lab in 2023, EVOLVE Rat Birth Control begins reducing rat populations after just one breeding cycle (4–6 weeks) and helps prevent rebound infestations when used as directed.
- NOT A POISON & SAFE PER FIFRA 25(b): Made with food-grade ingredients there’s no risk of secondary poisoning. EVOLVE Rat Birth Control is designated by the EPA as a FIFRA 25(b) minimum-risk pesticide and is safe for use around people and pets when used as directed.
- VERSATILE & EASY TO USE: EVOLVE Rat Birth Control can be used indoors or outdoors — in bait stations, near rat burrows, along fences and trees with Lure dispensers, staked in high-traffic areas, or scattered around gardens and sheds.
- HOW TO USE: For best results, place 2–12 pieces of EVOLVE Rat Birth Control sausages in tamper-resistant station(s) near signs of rat activity — along walls, near burrows, or by food sources. Maintain a continuous supply and check stations regularly. Expect a noticeable drop in activity within 2–3 months, with long-term control over time. For faster results, use in conjunction with traps.

*by S***G on 7 June 2026*

I would definitely give this five stars if I knew, for a fact that it worked, but I am not a rat obstetrician. Not sure if this works, but thrilled with the concept. I would rather them not have babies, then, poison, the rats, I despise. I have not seen sign of them, rats that is, Since implementing this product.
