Fastrac All-Weather Blox

Fastrac All-Weather Blox is a neurotoxin and there is no antidote if children or pets consume the bait. If children or pets are present, it is recommended that you use Contrac Blox since every doctor and vet has the antidote, which is Vitamin K1.

From Bell Laboratories, this poison is a quick and effective solution to controlling populations of rats and mice. Especially Norway Rats, Roof Rats and House Mice. Fastrac Blox are small, rough, all-weather baiting blocks with many gnawing edges.  The recognizable purple blocks have a hole in the center that allows it to be placed on bait securing rods in tamper resistant bait stations. BLOX work well in any condition — wet or dry, indoors or out. Fastrac Blox offers a lethal dose of active ingredient bromethalin in a single feeding, with the first dead rodents appearing in one or two days after bait consumption. Secondary poisoning ( e.g., a dog consuming the carcasses of rodents poisoned by Fastrac) does not readily occur with bromethalin.
