Using This Product in Arizona
Arizona homeowners deal with ants, roaches, and spiders year-round, and Ortho Home Defense's 12-month indoor residual means one application per year is sufficient for most interior treatments. Apply along baseboards, in closets, and around entry points in early spring before pest season peaks. The 1-gallon refill is particularly cost-effective for Arizona's larger homes and for treating the extensive perimeters common in desert landscaping properties.
