Application Method

Fumigate entire structure by sealing building under gas-proof tarp and introducing lethal concentration of sulfuryl fluoride or methyl bromide gas. Remove all people, pets, plants, food, and medicines. Seal structure with specialized tarps creating gastight envelope. Calculate fumigant dosage based on structure volume, temperature, and target pest. Introduce fumigant through distribution tubes. Maintain lethal gas concentration for 16-72 hours depending on conditions and pest. Monitor gas levels throughout treatment. After exposure period, ventilate structure and test to ensure gas cleared to safe levels before reoccupancy. Only method to eliminate drywood termites throughout entire structure simultaneously. Requires fumigation license, specialized equipment, extensive training, and strict safety protocols.

Timing

Can be performed year-round but best done in warm weather for faster gas penetration. Schedule when structure can be vacated for 2-4 days.

Frequency

One-time treatment eliminates all drywood termites present. Provides no residual protection - reinfestation possible. Retreatment if new infestation detected, typically many years later.

Preparation Required

Calculate cubic footage of structure. Notify neighbors per regulations. Customer removes food, medicines, plants, pets. Arrange alternate housing for 2-4 days. Obtain required permits. Coordinate with local authorities.

Follow-up Required

Aerate structure completely. Test air to ensure safe reoccupancy levels. Remove tarps and warning signs. Provide customer with completion certificate. Explain fumigation provides no residual protection. Recommend regular inspections.
