Fastrac Blox Poison Bait

Free Shipping on All Orders

Fastrac Blox is designed by Bell laboratories and contains .01% Bromethalin and is a fast and extremely effective rodenticide to help you control populations of rats, mice and even Norway rats and Roof rats. Containing many gnawing edges and a hole through each block, makes this product a great bait to place inside bait boxes or simply as a stand alone bait. A lethal dose of Fastrac Blox will happen in a single feeding with dead rodents appearing in just one or two days!

Target Pests

Fastrac Blox is used for roof rats and house mice along with anticoagulant-resistant Norway rats.

For Use In

Fastrac Blox is for use in residential homes agricultural buildings garage attic sheds yards industrial and commercial buildings food processing facilities trash/dumpster areas docks and port terminal buildings and related structures. Burrow Baiting with this product is prohibited.


Treatment Areas: Inside active burrows, along walls, gnawed openings, corners or concealed openings, between walls, or locations of rodent activity.

Rats: Place 2 to 12 blocks per placement.(15 to 30 foot intervals) . Adjust the amount of bait applied to the level of rat feeding expected at each bait placement.

Mice: Use 1 bait block per placement at 8-12 foot intervals. Larger placements (2 blocks.) may be used in areas of high mouse activity.

Sewers: For use in sewers, thread wire through block and securely attach to a stationary structure such as the bottom step of a manhole ladder or a sewer grate. Allow just enough wire for the block to rest on manhole benching. If benching is not present, suspend block a few inches above the high water mark or secure block on a board supported by opposing steps of the ladder. Securing block in this manner will prevent removal by rats or water. Use at least 15 blocks per manhole. Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease

Baiting Strategy: Highest bit consumption will occur the first day or two after treatment begins. After several days inspect the placement and replenish baiting sites where there is evidence of heavy feeding or continued rodent activity.

Normally, the volume of bait consumed will be significantly less with bromethalin baits than with anticoagulant baits. Although one night's feeding will usually provide a lethal dose, maintain bait for at least one week to provide all rodents a chance to feed on the bait. Continue baiting until all signs of feeding have ceased.

We highly recommend bait stations with the use of this product. Tamper-resistant stations for indoor use.

Coverage Area

Fastrac Blox can be used in and within 100 feet of manmade structures.

Time to Kill

Fastrac Blox will quickly kill the target pests usually in 12- 48 hours after initial feeding.

Active Ingredient

Bromethalin 0.01%

Fastrac Blox Poison Bait

Fastrac Blox Poison Bait

Fastrac Blox with the active ingredient, Bromethalin, is Bell Laboratories fastest-acting rodenticide formulation. An acute bait, Fastrac gets unsurpassed rodent acceptance and control, killing rats and mice in 2 or more days after consuming a toxic dose. Unlike most anticoagulant baits, Fastrac Blox is a neurotoxin rodenticide.


Bromethalin is a rodenticide approved by the EPA in 1984 to combat the world-wide problem of rodent resistance to warfarin-like anticoagulant (blood thinning) rodenticides. Bromethalin is the key ingredient in many rodenticides such as Fastrac blox.


More rats and mice can be controlled with less bait because rodents stop feeding after eating a lethal dose. Technicians save money and bait with FASTRAC BLOX.


Bell scientists developed a method of synthesizing Bromethalin that removes by-products and impurities, yielding the purest, most consistent Bromethalin available. This powerful active ingredient, in combination with Bell's highly palatable formulation, gets dramatic results in rodent acceptance and control.


The BLOX's multiple edges appeal to a rodent's desire to gnaw and BLOX are made with food-grade ingredients and small amounts of paraffin for a highly palatable bait. In fact, BLOX are the bait of choice in the pest control industry. Bell's patented All-Weather BLOX work well in any condition -- wet or dry, indoors or out. They're manufactured from Bell's unique extrusion process that yields a hard, multiple-edged bait with the palatability of a meal bait and the weatherability of a paraffinized bait.


The Fastrac Blox has a hole in the center which lets technicians place it on bait securing rods in bait stations, or nail or wire it in place. FASTRAC is colored emerald green for easy identification.

What if our dog eats it will 8t die?
A shopper on Oct 2, 2018
BEST ANSWER: A pet that eats Fastrac Bait Block should be taken immediately to your local vet. Because of the blood cloting and airway constricting components can be fatal. The pet and a bait block should be taken to the vet immediately.

However, if properly used and securely stored this should rarely happen if at all.

We have used this product for years with no incidents and have several dogs that are around the bait boxes daily.

Hopes this helps!
Should I expect the after smell of dead mice/rats in my home or will they make an attempt to escape my home in hopes for survival?
BEST ANSWER: If you are using this for mice, they will usually be something you will smell, but they are small and it is not as strong as a rat. Rats you have a 50 50 chance either way, because they will forage and move about outside at night and then nest inside.

Rat sorb and air sponges will work great.
