ZP TRACKING POWDER is a restricted-use acute, single-dose rodenticide containing the active ingredient, 10% Zinc Phosphide, which is used to control house mice. When ingested by rodents, ZP TRACKING POWDER comes in contact with dilute acids in the stomach, releasing toxic phosphine gas.
ZP TRACKING POWDER is a stable formulation with a long shelf life. Tracking powder contains a toxicant mixed with special carriers that adhere to the rodent's fur and paws. It is ingested when the rodent grooms. Tracking powder is insoluble in water which prolongs the effects of the powder, making it ideal for tough jobs.
Tracking powder is good to use under controlled conditions when bait acceptance is poor. Apply just teaspoon amounts in bait stations, along walls, by gnawed openings, in corners and concealed places, in spaces between floors and walls, or in locations where house mice or their signs have been observed.
Do not use tracking powder in drafty locations where it could become airborne or where it could contaminate food or surfaces that come in contact with food.
