The "Last Supper" for My Uninvited Guests
If you’re using the Key-Required Bait Stations, you need a "main course" that actually delivers. I paired them with Contrac Blox, and let’s just say the local rodent population has effectively been served its eviction notice. This stuff is the gold standard for a reason. The "Irresistible" Factor I’ve tried other hardware store baits that the mice seemingly walked right past, but they can’t seem to resist Contrac. The wax blocks are designed with multiple edges, which satisfies their need to gnaw while delivering the goods. I’ve noticed a significant drop in activity within just a few days of loading up my stations. It’s effective, efficient, and doesn't leave me guessing if it's working. Designed for the Long Haul What I appreciate most is how these blocks hold up. Living in the Midwest, I need something that can handle a bit of humidity or temperature swings without turning into a crumbly mess. These blocks stay intact inside the stations, meaning the bait stays fresh and appetizing for the targets until it's gone. Plus, the pre-drilled hole in the center makes it a breeze to slide them onto the securing rods in the bait stations. They also fit perfectly in the stations where they are supposed to. They also dont stink like many of the over the counter options and the bucket seals nicely. Safety First Because I'm using these in a 12-pack of locking stations, I feel much better about the whole operation. The blocks stay locked inside, away from pets and curious hands, while the "all-weather" formula ensures they don't degrade. It’s a professional-grade setup that gives me total peace of mind in my garage and storage areas. The Verdict: If you’ve invested in the stations, don't skimp on the bait. Contrac Blox is the real deal. It’s tough, it’s attractive to pests, and it gets the job done the first time. My pantry and workshop are finally defended properly.

Works great!
Works great, been using it for years on the recommendation of an exterminator. If you have a rodent infestation they WILL chew through the bucket itself to eat this stuff.

mice poison, voles poison, rat poison
Good product. Didn't see mice poop the day after I put down product. Very easy to use just put it where you believe will be the best place to block mice entry. Lasted a long time. Smell not bad. The label says to keep out of the reach of children so it's not safe. Can't say if it's a good value for money because this is the first time I've bought a product to deter mice. I like that it works in all weather conditions.

It’s what pest control companies use…
I had a serious rodent problem at my mom’s house. These mice must have been college educated. A pest control person told me that they actually learn. Once a mouse is caught in a particular trap the surviving mice avoid them. I started out with the obvious snap traps and went thru a variety of those and from that point I could find no takers on those traps. I purchased an electric trap which was immediately successful but again, I had no second customers. A friend of mine had the same issue and rather smartly, peered into the service van and took note. This was the product that the commercial company was using. She told me it was available on Amazon and I quickly made the order and purchased the black bait stations to deploy the bait. I have a cat and was concerned about him accessing the bait but this product, inside the bait station makes it impossible for any animal to consume. The plastic boxes for the bait are additionally locked for added safety. I’ve not seen or heard any unwanted visitors since using this product. This is an awesome way to rid yourself of mice, after all, the commercial industry uses the same thing.
