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.πŸ’— Be patient & continue baiting them, it works over the course of several days & ample blocks available for the taking. Review: 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! ## Features - CONTRAC BLOX is specially formulated with an optimal blend of food-grade ingredients and a small amount of paraffin Highly palatable, yet weatherable, CONTRAC works well in wet and dry conditions. Single-feeding anticoagulant rodenticide containing the active ingredient, Bromadiolone. Can not ship to CA - Application: Recommend changing bait out every 40-60 days if n - Pet safe: Contrac is LESS toxic to non-target animals in both primary and secondary poisoning situations than other single-feeding baits. The antidote, Vitamin K1, is readily available. Always use a tamper resistant bait station to keep pets and children away ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003ORPOJ8 | | Active Ingredients | Bromadialone | | Best Sellers Rank | #33,274 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #281 in Pest Control Baits & Lures | | Brand | Bell Laboratories | | Brand Name | Bell Laboratories | | Customer Reviews | 4.6 out of 5 stars 957 Reviews | | Item Form | Gel | | Item Weight | 18 pounds | | Manufacturer | Bell | | Model Number | CB4051 | | Part Number | en-pstrng-453 | | Target Species | Insects | | UPC | 030835400492 | ## Product Details - **Active Ingredients:** Bromadialone - **Brand:** Bell Laboratories - **Item Form:** Gel - **Item Weight:** 18 pounds - **Target Species:** Insects ## Images ![18 LB Contrac Blox Rodent Control Rodenticide Kills Mice & Rats - Image 1](https://m.media-amazon.com/images/I/61iENhZL-vL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works..Update *by M***L on February 12, 2024* My birdfeeders drew rats in my garden. 2 neighbors have gardens that join my property.

Buying my second bucket this week! ### ⭐⭐⭐⭐⭐ Made the rats disappear. *by B***L on November 16, 2024* 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. ## Frequently Bought Together - 18 LB Contrac Blox Rodent Control Rodenticide Kills Mice & Rats - Qualirey 24 Pcs Mice Station with Key Triangle Bait Station Reusable Rodent Trap Bait Box, Keeps Children and Pets Safe Indoor & Outdoor, Bait Not Included, Suitable for Small Mice (Black) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/4712974-18-lb-contrac-blox-rodent-control-rodenticide-kills-mice-rats](https://www.desertcart.tn/products/4712974-18-lb-contrac-blox-rodent-control-rodenticide-kills-mice-rats) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-27*
