A practical operational guide for HOA boards facing termite fumigation. Covers the approval process, resident coordination, Nylofume bags, key collection, liability, and what to do when a unit owner refuses.
Step 1 — Get a Licensed Termite Inspection First
Before any board vote, you need a written inspection report from a California SPCB-licensed inspector. In California, structural pest control falls under Branch 1 (general pest) or Branch 3 (wood-destroying organisms) licensing. For a WDO (Wood Destroying Organism) inspection, you need a Branch 3-licensed inspector or company.
What the inspection should cover:
- All accessible attic spaces (including all units' attic access)
- Subarea and crawl space if applicable
- All garages and carports
- Exterior eaves, fascia, window frames, and trim
- Accessible interior wall sections where frass has been reported
Before the board vote, get 3 quotes. You need actual numbers to make the financial case and to demonstrate due diligence. A single quote isn't enough for a vote on a large expenditure.
Step 2 — Bring It to the Board
Present the following at the board meeting:
- The written inspection report with photos (if possible)
- 3 written quotes with total cubic footage, rate per cubic foot, and all-in cost
- A proposed timeline: inspection → vote → resident notice → fumigation date
- A budget breakdown: fumigation cost, permit fee (~$300–$500), Nylofume bag cost, resident relocation reimbursement (2 nights × number of units × $160–$200/night)
Most CC&Rs require a majority board vote for expenditures above a threshold. For a large complex, the total cost may trigger a membership vote requirement — check your governing documents before scheduling anything.
Important: Frame this as a maintenance issue, not an emergency. Boards that treat it as routine maintenance (which it is) generate less resistance than boards that present it as a crisis.
Step 3 — Notify Residents (30–60 Days Out)
Written notice is required. Check your CC&Rs for the specific timeline — most require 15–30 days minimum. We recommend 30–60 days to reduce conflict and give residents adequate time to arrange lodging, pet care, and any special medical equipment needs.
What the notice should include:
- Confirmed fumigation date range (typically a 3-day window)
- What residents must do to prepare
- What the HOA will provide (Nylofume bags, relocation reimbursement)
- How to submit relocation receipts for reimbursement
- Contact person for questions
- Attached FAQ document
Consider holding an informational meeting or webinar. Residents who have questions get them answered at once rather than individually. Most fumigation companies will participate in this meeting at no charge.
Step 4 — Coordinate Preparation
Nylofume bag distribution (1 week before):
Nylofume bags seal food, medicine, tobacco, and pet food against Vikane gas penetration. The fumigation company provides these. Plan for distribution — door-to-door is most effective for large complexes.
Key collection:
Every unit must be accessible. Establish a clear key collection process: lockbox, management office drop-off, or direct handover to the fumigation crew. Create a checklist and confirm every unit is accounted for before the tent goes up.
Alarm systems:
Contact your monitoring company 1–2 weeks before fumigation. Alarms must be disabled during treatment. The fumigation company will need the access code and monitoring company contact information. Failing to coordinate this results in false alarm calls and potentially delayed fumigation start.
Utility coordination:
Gas shut-off is required. This is typically scheduled by the utility company and coordinated by the fumigation contractor. Plan 2–3 weeks ahead — utility scheduling can be slow.
Special situations to identify in advance:
- Residents with fish tanks (fish must be removed; tanks cannot be simply covered)
- Medical oxygen concentrators or other powered medical equipment
- Residents who need extra lead time due to mobility limitations
Step 5 — The Fumigation Itself
Tent installation: The fumigation crew will walk rooflines to drop tarps and secure the tent. Residents and the board should expect significant visual disruption for 2–3 days. Inform neighbors outside the complex if the tent installation will affect adjacent properties.
Gas introduction: Vikane (sulfuryl fluoride) is introduced with chloropicrin as a warning agent. Once the gas is introduced, no access is permitted — not for the fumigation crew, not for residents, not for board members.
Warning signs: Required by California law — posted at all entrances and visible from the street.
Minimum exposure period: Determined by the fumigator based on total cubic footage and the ambient temperature. Colder weather requires longer exposure periods.
Step 6 — Re-Entry and Clearance
Air quality testing: The licensed fumigator uses a Fumiscope device to test for residual Vikane in every occupied area before re-entry is permitted. This is a legal requirement, not optional.
Clearance certificate: Issued by the fumigator once all readings meet California clearance standards. Keep this in HOA records permanently — it's your legal protection.
Resident notification: Once cleared, notify all residents immediately. Typically re-entry is authorized 2–4 hours after testing begins.
Post-fumigation: Frass (termite pellets) may still be visible after fumigation — this is completely normal. The gas kills the termites but does not remove their droppings. New frass appearing months later would warrant reinspection.
What to Do When a Unit Owner Refuses
This happens more often than boards expect, and it's important to handle it correctly.
Step 1 — Explain the structural reality. Shared framing means their refusal endangers all neighbors. Send a written explanation that makes this clear, with the inspector's report attached.
Step 2 — Document everything in writing. Every communication, every refusal. This creates the evidentiary record you'll need if legal action becomes necessary.
Step 3 — Follow HOA enforcement process. This typically means a formal written notice, a cure period, and escalation to the board's authority.
Step 4 — Seek legal counsel if necessary. California law allows the HOA to petition for a court order compelling access when an infestation threatens the common interest development. This is a last resort but it exists for exactly this situation.
Liability note: The refusing owner may be held personally liable for termite damage to neighboring units if their refusal demonstrably allowed the infestation to spread. Communicate this clearly and in writing.
