After applying OsmoFume to a pole, which action is required before plugging holes?

• A. Apply one ounce HHCB per stick of OsmosFume before plugging holes
• B. Do nothing
• C. Apply MITC Fume
• D. Remove OsmoFume

Answer: (A)

The action being tested is about the proper sequence to ensure the fumigant works effectively and stays contained. After you place an OsmoFume stick in each hole, you should apply one ounce of HHCB per stick before plugging the holes. HHCB serves as a carrier for the fumigant, helping it distribute through the wood and aiding a proper seal when you plug the holes. This step prevents gas from escaping and ensures the pole is treated evenly. Skipping it could leave portions untreated or allow leaks. The other options don’t fit the required procedure: doing nothing ignores a mandated step; applying MITC Fume separately isn’t part of the sequence; removing OsmoFume would undo the treatment.
