What customers say
Customers highly value the immediate and powerful knockdown effect of this yard treatment against severe flea infestations, often seeing relief within a day. The concentrate format is praised for offering excellent coverage on large properties, suggesting good initial value. However, satisfaction is significantly tempered by concerns over longevity. While the initial kill is strong, many users report that pests reappear quickly, often within a few weeks, failing to meet expectations for sustained protection. This inconsistency in residual effectiveness is the main detractor. While it serves as a fast-acting solution for immediate crises, its reliability as a long-term preventative barrier remains questionable for many users.
