We make one of the products. No house score, no weighting, just the labels. When another product has the better number, we show that too. Methodology

EPA data retrieved 2026-08-18. Registrations and labels change, and our reading of a scanned label can be wrong. Always check the product label you actually have before you buy or apply anything. If you spot a mistake here, email hello@longsleeve.com and we will correct it. Published by Longsleeve, not affiliated with or endorsed by EPA.

Every cell is EPA data or the product’s own federal label, retrieved 2026-08-18; registrations and labels change, so verify against the current product label. Methodology.
