Coumatetralyl is an anticoagulant rodenticide that is being re-introduced to the UK as an alternative active ingredient to Difenacoum and Bromadiolone, for the control of rats only.
Coumatetralyl is commonly combined with grains and other cereals to create rodenticides in soft block formulations with a 0.375% w/w active ingredient content.
Coumatetralyl soft blocks are considered to be a good choice in situations where bait-shyness or neophobic reaction to other baits are being encountered by the operator. The soft block is shrouded in a sachet to keep the bait fresh and palatable to the rats. Coumatetralyl poisons are professional use only products.
PestFix sells the following brands of coumatetralyl-based poisons: Romax Rat CP & Bayer Racumin
