## 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: I have a minor rat problem in both my shed and attic. I began using Evolve a couple months ago. It is easy to put out, and I don't worry about my kids or pets messing with them, like I would actual poison. I've even cut a few of the sausages into smaller pieces and they hold their form. They get eaten nightly, which is great! However, I got tired of feeding the rats and I began putting out traps. I have three traps in the attic and three traps in the shed. At first, I was using my secret family bait recipe (peanut butter and chocolate chips) wasn't touched. Surprised, I put small pieces of Evolve Sausage on half of the traps. Now, every time I check on the traps, the sausage piece is missing, but I have yet to catch a rat! The traps with peanut butter and chocolate remain untouched. So, a few takeaways are: 1. Rats love these sausages more than traditional "baits." 2. While I continue to battle my rats, I'm comforted knowing they are not breeding, which would prolong my rat problem. I have not observed increased rat activity nor caught baby rats on my trail cam. 3. I'm at peace with the presence of these sausages on my property knowing that they pose no threat to people, pets, or downstream wildlife predators.
Review: I'm giving it 4 stars because I haven't had the bait long enough for it to show it's working. It takes time in the system to do what this product is claiming--shutting the reproductive system down. I will say though that I put it out the day I received it, and within 2 hours a rat had taken it completely away--I assume to eat. I will edit this review when I see the results, either way. The product is very sturdy, without odor, and I haven't had to clean it up due to the whole sausage being taken off somewhere else.

## 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 R***E on 22 November 2025*

Something is eating them is all I can say. Whether they will work, don't know. Not sure how often to refill my bait house thingee. I'm gonna do it biweekly. My problem is outside during winter bird/squirrel feeding season. Rest of the year not a sign of them. Glad this exists as poison is a no no. Other animals are dying after eating a poisoned rat and that is unacceptable. UPDATE: I got the 6lb pail as I am putting them out more frequently. Don't get the pail, get the pouch. Opening the pail is difficult, they protect it like it was gold or something. I had to use tools to get it open. Is it working? I would say so, I see less activity at my bird feeder. In the past as many as 7 and now about 2 or 3.
