Rat Poison Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Catchmaster is the best-performing rat poison brand in July 2026, moving 40,000 units across 3 ASINs for 37.0% of Top 10 volume. Tomcat follows with 28,000 units (25.9%), ahead of Grandpa Gus's on 10,000 units (9.3%).

With 6 brands splitting the Top 10 and 72.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $17.30 to $32.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B012VJLZOM booked 9K units at $6.69, with ▲ 50.0% MoM change. On the growth side, B01MT6BOR0 leads positive momentum with ▲ 300.0% MoM growth on 4K units, with B0DK9Y2LTR close behind at ▲ 100.0% MoM on 4K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
