Tomcat with bromethalin place pacs contain the premium active ingredient bromethalin, excellent for proven control of high rodent populations and severe infestations. Bromethalin is an acute, non-anticoagulant active that will begin to kill rats and mice in two or more days, faster than anticoagulant baits. Due to a quick knockdown when compared to anticoagulants, more rodents can be controlled with less bait. Pellets are packaged in individual, pre-measured 3 oz place pacs, which protect the bait and make it easier to get into tight spaces or hard to reach locations.
