In non-residential public buildings, where must a notice be placed?

• A. At entrances to the room or area to be treated
• B. On the exterior of the building
• C. In the lobby only
• D. In the pest management file

Answer: (A)

Posting a notice at entrances to the room or area being treated ensures anyone about to enter sees the warning before exposure. This placement directly informs occupants and visitors who will actually enter the treated space, allowing them to take precautions or avoid the area if needed. Putting notices on the exterior or only in the lobby can miss people entering other doors or rooms, and relying on a pest management file is just for record-keeping, not a public warning. So the most effective and protective location is at the entrances to the room or area to be treated.
