TPC introduced to Trinidad a method of sealing and fumigating entire structures to kill Drywood termites. This can be done by two alternative methods. External fumigation is done by ‘tenting’ a building with purpose made gas impermeable tarpaulins, making it air-tight. Gaseous fumigant is then pumped into the building. Internal fumigation produces the same end result, but it involves sealing air vents, windows and doors from the inside.
