The bottom line: it is best for users who need a highly palatable, weather-resistant single-feed bait that keeps bait stations stocked for weeks; the active ingredient Bromadiolone allows rodents to receive a lethal dose in one feeding, making it particularly useful where a quick, effective clean-out followed by maintenance is required.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive ingredient:\u003c\/strong\u003e Bromadiolone provides single-feed anticoagulant action so rodents can be controlled quickly after one feeding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlock size:\u003c\/strong\u003e Each bait blox weighs about one ounce, which makes placement and consumption predictable for both mice and rats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeather resistant:\u003c\/strong\u003e Formulated with paraffin so the bait remains effective in wet and dry conditions, reducing the need for frequent replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePalatability:\u003c\/strong\u003e The blend of food-grade ingredients results in high acceptance by rodents, improving control success even with warfarin-resistant Norway rats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlacement guidance:\u003c\/strong\u003e Clear spacing recommendations for rats and mice help maintain an uninterrupted supply of fresh bait until activity stops.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is suited for homeowners, maintenance staff, and pest control professionals seeking a reliable clean-out and maintenance bait for both mice and rats, including populations with warfarin resistance.
