What is the maximum height above grade for applying pyrethroid sprays to the side of a building?

• A. Two feet above grade.
• B. Three feet above grade.
• C. Four feet above grade.
• D. Five feet above grade.

Answer: (B)

Pesticide label directions set where and how you can apply products. For pyrethroid sprays on the exterior side of a building, the limit is three feet above grade. This height helps reduce drift and protects people, plants, and non-target areas while still treating the area where pests are most likely to enter at the base of the structure. Therefore, the maximum height allowed is three feet above grade. Higher heights would exceed the label restrictions, while lower heights are permissible but not the maximum.
