PredaSTOP for Stoat Control

PredaSTOP is a green paste used as a bait for Stoats and Feral Cats. It contains para-aminopropiophenone also known as PAPP, which once consumed makes the predator lethargic and drowsy which then leads to death. PAPP converts the haemoglobin in red blood cells to methaemoglobin that blocks the flow of oxygen to the brain and heart.

PredaSTOP is packed in a syringe or a pottle.

Use only in bait stations (ensure no domestic animals have access to the bait station).

Important: You need a Controlled Substance Licence (CSL) to buy, store and use these products. We must sight and record the details of your CSL (and in some situations, your Approved Handler Certificate) before you buy.
