When treating large open spaces to reach flying pests, which method is appropriate?

• A. Broadcast
• B. Space
• C. Crack & crevice
• D. General

Answer: (B)

When pests are flying, you need to reach them in the air, not on surfaces. A space spray disperses a fine aerosol into the open volume, allowing contact with flying insects as they move through the space. Surface-focused methods like applying to walls or broad surface areas won’t effectively reach pests in flight, and crack & crevice treatments target narrow gaps rather than open air. So, for large open spaces and flying pests, using a space spray is the appropriate approach.
