One-Bite-Wonder Well worth the money it costs!
I have a cabin in the woods. We always have rodent issues, until my cousin told me to get Contrac Blox. We have used all of the other types of blox and poisons with low impact. We left the cabin in May with the Contrac Blox distributed, and when we went in July, we only found 3 dead mice, and never heard or saw a live one! There has NEVER been a visit to the cabin where we saw no live mice or rats! Amazing Product! The price is worth it, and you actually have it last longer than others because it is so potent! We call it the 'ONE BITE WONDER' !!! Buying my second bucket this week!

Works..Update
My birdfeeders drew rats in my garden. 2 neighbors have gardens that join my property. The rats ate bellpeppers, figs in a covered, closed greenhouse & a pineapple plant down to the ground in a rabbit proof bed. I had to stop feeding birds & cover water source nightly. I caught several rats with tunnel traps but the rats got smart & stopped coming to those traps. I bought Contract & 2 lock boxes & peanut butter powder to entice the rats. So far the rats havent visited those yet, however I placed a block into a tunnel burrowed around my porch, & twice something died, as the smell was awful. All rat signs have disappeared except I have had 1 or 2 blocks eaten every night that I place inside a wooden pallet covered by a large empty water cooler, that is dog proofed, etc. Those rats are by my neighbors areca palms & bamboo that seems to be the rats main home. I will continue to place blocks there until the eating stops, then monthly. No more signs of rats in our greenhouse & gardens. No dead rats in my yard but Im sure my neighbors rows of bamboo/ palms are full of dead rats. I will continue to buy Contract as rats are rampant here in Fl. I highly recommend. UPDATE...love this stuff. Been using for a week or more. Rats are significantly knocked down. Burrowing rats under the lanai have been XXX & the smell has forced me to buy potpouri packets to make it tolerable twice, but so worth it, Im finding less tunnels/ burrows. Greenhouse rats are gone. Under the areca & bamboo next door was over run with rats. Too smart to come to the locked feeders. Ive had great luck using a pallet at the corner of my yard that has been pet proofed for my neighbors, placing blocks inside the board spaces. Rats went from eating 1 block a night, to two, then 5 blocks, started seeing drunk rats trying to get to my neighbor's pool, he ended them. I could hear rats flopping at night in the palm mulch when I check bait before going to bed. Last night was 1st night no blocks eaten & the stench coming from other neighbor's palms/bamboo mulch is significant. Ive even purchased diff bait to keep them interrested in conjunction to Contract because the more powerful baits cant be shipped to my Fl locale. No more rats eating my veggies so far. Looks like Im winning the rat war.💗 Be patient & continue baiting them, it works over the course of several days & ample blocks available for the taking.

Added Pb fit - worked much much better
At first I had no luck with this bait. Had the bait in bait stations throughout my house. In corners, closets etc. but the bait remained untouched. I believe they are too cautious to go in them where I had the stations set up. I started trying this bait again about a year later, but this time placing in the subfloor where I had seen quite a bit of activity. I also put the bait in a plastic bag with a dash of pbfit peanut butter powder to make it more enticing before placing. It worked like a charm. First they licked all the pb off and eventually the bait turned into a small pile of dust as it was consumed. I have motion detector cameras set up and activity decreased every day. One morning I heard some flopping around in my air ducts in the basement. I knew mice were likely meeting their demise. So far I have not seen any dead mice. However, I’ve noticed a slight odor, but it actually went away rather quickly. Nothing that mint oil in the diffuser won’t eliminate. I live in a row home so I don’t think sealing them out completely is an option. So this will have to be a staple in my mice battles. I’d give 5 stars if I didn’t have to add pb fit to the blocks.

Dropping like flies.
Easy to use.... loaded in dispensers and within days noticed dead mice and rats around barn. It works really fast and the only downside is collecting carcasses. I'd rather do that than have them running around. Be diligent picking them up because other animals can eat them. They do smell but it's a different smell. I have picked up so many. I have a poultry farm and were overrun with rats... I can say I was feeding a lot of rats. I would recommend this product. I'm filling up my dispensers weekly. And picking up carcasses daily now.. it takes about a week to work... then they drop like flies.

Made the rats disappear.
The caretaker of my farm got lazy and started just throwing grains down on the grain in the chicken coop after locking them up. By morning, all the grain was gone, so he thought the chickens were chomping down all night. I noticed some tunnel holes in the edge of the walls and so I put in a camera. It was horrifying! After everyone was put to bed, hundreds of rats came out and ate all the grain. Time for a remediation. I contacted a pest control company and they said the problem was so bad they didn't want to attempt it. So it was on me. I bought a BurrowRx machine and smoked out who I could. Then I noticed that they were all running to a mature compost pile. A few minutes with the tractor took care of that problem. There were so many babies in there that the chickens had a hay-day. Only an occasional rat to see then, but too many. So I bought this product to keep them at bay. This poison works great. It's been four years now and I haven't seen a single rat. I was concerned at first that the rats would die and the chickens would eat them and get poisoned. That never happened; it seems like the rats go into a hole when they're bleeding out all of their orifices, so they are safe from the chickens. Also, I believe that other rats eat the poisoned carcasses and succumb. So a one-two punch for rats.
