Talon G is a rodenticide that comes in 25 gram packs and shaped like mini pellets. The mini pellets are designed to be placed in crawl spaces where a typical bait station won't fit.
The active ingredient in the bait is brodifacoum. This is effective against both warfarin-resistant rats and mice with a single feeding. Because of the mini pellet size, this is very attractive to small mice.
One order comes with 2 pails. Each pail contains 150 x 25 gram packs. EPA does not allow these to be sold by single pais.
