When using granules to treat for outdoor pests, which area should be treated?

• A. treat pavement areas
• B. treat around the bases of trees
• C. apply to ornamentals only
• D. treat perimeter of the structure around where soil and sod occur

Answer: (D)

Outdoor granule treatments are most effective when used as a barrier around the exterior of the structure, at the edge where soil and sod meet. This puts the treated zone directly in the path crawlers use as they move along the ground toward the foundation, creating a residual barrier that pests must cross to reach entry points. Treating only pavement, around trees, or only ornamentals misses these key travel routes and won’t provide the same level of protection for the structure. Placing the granules around the perimeter where soil and sod touch ensures broader, more consistent coverage and better prevention of infestations.
