Contrac Blox

Walt Cline - Pest Control Professional Pro Tip: "Contrac Blox has been the most consistent rodent bait over the years. Rodents love it, but dogs love it as well, so make sure to use a tamper resistant bait station. If you need recommendations on bait stations, look at the choices below or call us. You can also get Contrac with Lumitrack . Lumitrack, used with a black light reveals rodents droppings when searching in the dark. All of the bait we sell is fresh. Rodents love fresh bait.

California has placed Contrac Blox in a restricted use category. We can not ship Contrac to California without a pest control license. If you are a pest control operator or a certified applicator in California, please call us with your license number. Other single feed baits (non anticoagulants), such as Takedown, Top Gun, Fastrac, and Terad3 are available in all states.

Great product
As a licensed pest control technician, I highly recommend this product. I do disagree that the product is not effective on voles as I have used this to eliminate vole activity with excellent results. It works on Norway rats as well, but I’d recommend dusting rat holes with Ditrac for rats for better results.

Irresistible to mice and highly effective
This is a top notch product. I've tried alternatives from the big box stores and none come close to this product. We have two barns containing animals and feed supplies. I always keep my bait stations full. If just starting out, the mice will eat the bait pretty rapidly. However, this tapers off after a few weeks to minimal feeding, meaning your have rid most of the rodents. Don't let your bait stations go empty, or mice will return and multiply. I will never buy anything else and this is worth every penny.

The best rodenticide!
Great product. Rodents go for it!
I use 9 triple block bait stations on my rural property. I have not found a rodent dropping in my pump house, big shop or home. I set a box near my tractor and RV. Rarely find a carcass but the bait boxes are filled with droppings. Used about 10lbs last year. Product delivers results immediately.

Works Great on Rats!
I've been using this for years in Protecta bait stations around the house. Rats love it and I've never had a problem. We had quite a rat infestation around our bird feeders last summer, and I was able to wipe them out in about a week.

The product does not seem to work as well on Voles (field mice), however. The don't seem to be attracted to it very much. I am using JT Eaton Bait Blocks on them that contains peanut butter and other ingredients that attract them.

Great product
The rats took out 10 of 20 blocks in the first week and a half. Rodent activity is starting to stop.

Expensive, but worth every penny
I have used this in the past and am now about to place a new order. I can attest to its efficacy in killing rats! I can also attest to its snackability for dogs. While baiting areas with contrac blox, keep an eagle eye on your dog's poop. If you see that it's coming out a telltale teal color, go to the vet immediately and get vitamin K pills. This rodenticide prevents the body from normal production of that vitamin for the next 30 days or so, which means no ability for blood coagulation until vitamin k starts to be produced again. My dog was fine after a 30 day regimen of vitamin k. The rats . . . not so much. A pest control professional recommended this product to me.

Kills rats dead
Its not as fast as Final Blox, but its effective. Its fine to use if you dont mind it taking 4 days to work. If you need fast, you want final blox.

Otherwise I use it in bait stations around my property, save the final blox for something really bad.

Worth every penny
Excellent control of mice. We had an increasing amount of sighting and mouse droppings in the house. A pro was paid $200 for 15 minutes of work. He used this product. I ordered this myself since I decided to avoid his $50/ month maintenance fee.

The product worked immediately!

Contrac bloxs protect my valuables from rodents
Great blood thinner for rodents! It was in the basement that I found the 2 dead mice after putting it out. There’s 2 bait stations in the garage. 1 sets in the engine of my 429ci Ford Mach 1. Baited in the other 2 vehicle engines too. Big bait box with 4 Contrac bloxs behind the house at the 22Kw Generac. Also Contrac blox in a bait box in my gas shed. Great product that is protecting my valuables from rodents causing damage. Highly recommend.
