What is a common application of borates in pest control?

• A. Spot treatment of existing infestation.
• B. Full-area spray.
• C. Soil drench around plants.
• D. Fogging.

Answer: (A)

Borates are used in pest control as a residual, slow-acting option that pests must ingest after feeding on treated surfaces. Because of this mode of action, they’re most effective when applied directly to where insects hide and feed—cracks, crevices, behind appliances, and other hotspots—so a spot treatment targets the infestation directly and leaves a lasting barrier. A full-area spray isn’t ideal because borates work best through contact and ingestion in localized locations rather than coating large areas, and fogging isn’t suitable since it relies on aerosols and doesn’t deliver the ingestion-based kill borates require. While a soil drench around plants has its uses for certain pests, it’s not the common approach for indoor pest control; borates are chosen for targeted spots where pests are present.
