Review: Weird but effective! - I know this will sound weird. Here it goes, the property behind us was clear-cut about years ago. All the wildlife was scattered and was (sadly) displaced, including the rats. We ended up with a refuge camp in our crawl space, bike shed, cars, storage... all over our property. I'm sure we had over 40 rats on our quarter of an acre. They were everywhere! And they were having more and more babies! Neighbors had traps out and hired exterminators. It was not helping. So I began looking into solutions. Each rat (Norway rat) will have a litter of 5-12, -7 x per year! Killing them after the fact (not in my DNA) seemed like whack-a-mole. Also, it has something called a "boomerang effect," and the population actually grows! Then I saw a show on how NY is trying to get its rat population under control, and I discovered rat birth control! Gave it a try. The first few months felt very counterproductive, as here I was actually feeding them! Actually, the first year felt counterproductive, and I felt a bit mental. Then the next year, the rats stopped breaking into our storage looking for food, eating my flower bulbs etc. But still, there were a lot of them, and now they were well fed! This is year 3. Here is what has happened: The population is -7 adult rats. I know this because they are super tame and not afraid to come out and allow me to do a head-count. (unless our Jack Russell is out) When they are out, they are easy food for our sparrow hawk and owls. And, I also noticed that the male rat completely defends its territory (AKA, my territory), not letting new rats onto our property. The population hovers around 5-10. Every once in a while, they have a litter (about every 4 months), and we get about 2-4 babies. 1/2 of those typically survive (we have a good amount of predators). The rats on our property now have their burrow and are not getting into my things, my flowers, etc. They keep other rats out (so now they are working for me), and the population is nowhere near 40+! Still, does it feel weird to feed them this sauceage thing? Yes, I know I hand out more sauceages every night than recommended... about 2-3/night, but they literally ask for their saucage every night! We have this thing now, this understanding. and it's just ... different. It works, takes time, and requires a shift in thinking. Also, while the population shrinks and is kept under control, securing the human spaces is super important. I.e., We had our crawl space closed off, all the little cracks and spaces they could get into, we put a stop to that as well. It works. You will feel weird. But it works.
Review: Pest control and liberation for female mice - I bought Evolve Rat Birth Control Soft Bait Sausages expecting population control. What I didn’t expect was to accidentally establish a tiny rodent socialist republic behind my shed. These sausages don’t poison, don’t murder, and don’t spark dramatic soap-opera deaths. Thank the gods! I don’t want to live with mice but I don’t want to murder them and poison other wildlife! Instead, I calmly introduced the concept of collective responsibility to the field mouse community that like to patrol the perimeter of my abode. No more unchecked capitalism of reproduction. No more surprise litters. Just long-term, sustainable population management. From each according to their appetite, to each according to their uteruses remaining blissfully empty. The field mice probably still show up, still snack politely, and still live their nocturnal little micey lives, only now without the relentless pressure to out-breed one another. Frankly, I’d guess they are much calmer. More reflective. Possibly reading tiny manifestos. ⚠️ Important Side Effect Warning: After a few weeks, you may hear faint but unmistakable celebrations coming from the shadows. That’s not wind. That’s the sound of pregnancy-free female field mice toasting their newfound bodily autonomy. Tiny clinks of invisible champagne glasses. Occasional squeaks that sound suspiciously like “solidarity.” Pros: •Not a poison •Long-term population control •Ethically confusing but emotionally satisfying •Promotes rodent liberation & family planning Cons: •You may feel like a benevolent overlord •The mice might unionize next In summary: if you want to control field and deer mice without violence, without guilt, and with a dash of ideological satire, this is the product for you. (I use a bait station weighed down because the raccoons love these and will eat an entire sausage) Five stars for humane pest control and for accidentally running a most progressive program in my backyard.

## 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.
