What is fumigation prep work?

What is fume prep?If a house or other building is going to be fumigated for drywood termites (not subterranean termites), certain things must be done for the tent to go on and to effectively seal the structure.  We call that “fume prep” work or “fumigation prep” work. It is sometimes included in the cost of the fumigation, and sometimes not – so if this work is being done at your property, be sure to ask if it’s part of the bid!  If it’s not included, there are companies that can be hired to do these jobs if you do not want to or cannot do them yourself. (If you need one in Silicon Valley, please email me and I can give you a name or two.)

Anything which obstructs being able to enclose the home or building must be cut back, disconnected or removed.  For instance:

  • fences or gates which touch the building must have a few slats or sections removed so the tent can be placed next to the house
  • bushes, hedges, trees and other plants which are adjacent to the house must be trimmed back or pulled away as much as possible – at least 12″ from the structure (if trees are touching it, they must be trimmed)
  • any other structure such as a trellis or deck must either be included with the fumigation or separated from the house so that a tent can go between it and the house
  • downspouts connected to French drains must be disconnected at the ground
  • loose gravel, tanbark or mulch needs to be raked back or removed at least 12″
  • any stored items up against the building must be removed (more…)
