During fumigation, the building is tented for 24-48 hours. Vikane gas is then pumped into the sealed structure, replacing the oxygen. Vikane penetrates hard to reach areas like walls voids, attic spaces, eaves and door frames. After treatment, our technicians will remove the tent and air out the structure. We will thoroughly inspect the structure before we allow occupants to return. Fumigation service is warrantied for 3 years after service.
