About the Active Ingredient - Brodifacoum is a highly lethal vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger mammalian pests such as possum. it is characterized as a "second generation" or "superwarfarin" anticoagulant. Brodifacoum steadily decreases the level of active vitamin K in the blood. Vitamin K is required for the synthesis of important substances including prothrombin, which is involved in blood clotting. This disruption becomes increasingly severe until the blood effectively loses any ability to clot.

    An effect product for rodents

    Review by on Jan 28, 2016

    We feed birds and seed spill around the feeders brings in some undesirable rodents that end up tunneling where you don't want it. The TomCat bait stations and bait chunks, we have been able to effectively manage unwanted rodents.

    Great product

    Review by on Dec 5, 2015

    The bloks work great. Just screw them down to a board that way the pack rats can't carry them off. Been using them for years.

    Does the trick!

    Review by on Oct 16, 2013

    I have used this product in my garage and barn against roof rats for several years. It kills faster and better than other baits, and rodents seem to eat it better than others I have used. It's one of the most effective baits available. I can no longer get it at my local feed store and farm supply, so I am glad that QC stocks it!

    Wonderful Product

    Review by on Feb 28, 2012

    I have tried several products side by side and the mice and rats will eat this product at least 4 to 1 over any other product I have tried. It works great in my hog sheds.
