What steps should you take to minimize drift when applying pesticides indoors?

• A. Use high-draft nozzles to maximize coverage.
• B. Apply only in dry rooms without ventilation to prevent humidity.
• C. Increase spray pressure beyond label guidelines.
• D. Use low-drift nozzles or atomizing devices appropriate to indoor environment; maintain proper ventilation; protect adjacent rooms.

Answer: (D)

Drift is spray droplets moving away from the target area, which indoors can carry pesticide into other rooms or spaces. To minimize this, choose equipment designed to limit off-target movement—low-drift nozzles or atomizing devices that are appropriate for indoor use. These produce droplets and spray patterns that stay more within the treated area. Pair that with proper ventilation so airborne residues are diluted and removed rather than lingering or moving to other rooms. Finally, protect adjacent spaces by closing doors or using barriers to physically separate the treated area. This combination reduces exposure risk and keeps the application focused where intended.
