Which statement about OsmoFume and HHCB is accurate?

• A. HHCB dosage is optional
• B. HHCB dosage is mandatory
• C. HHCB dosage is unnecessary
• D. HHCB dosage must be applied per stick before plugging holes

Answer: (D)

Applying the HHCB dosage per fumigation stick before sealing the holes is essential because it fixes how much fumigant will be released from each stick. This per-stick dosing ensures a consistent emission rate, which makes the treatment effective and predictable while also protecting handlers and occupants from unexpected exposure. The dosage step is not optional or unnecessary; it must be done for every stick before you plug the holes so the release starts correctly through the vented openings. If the dosage isn’t applied as instructed, some areas may receive too little fumigant and others too much, compromising pest control and safety.
