Flea Spray Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Repel is the best-performing flea spray brand in July 2026, moving 50,000 units across 1 ASIN for 29.4% of Top 10 volume. Ortho follows with 30,000 units (17.6%), ahead of Cutter on 20,000 units (11.8%).

Volume is spread across 8 brands, with the top three holding 58.8% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $7.48 to $20.06, 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: B07PXHQ5JR booked 10K units at $42.97, with ▲ 11.1% MoM change. On the growth side, B0C1Q39Q9R leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B00AT6FY6A close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
