Whole-structure fumigation, prescribed honestly

When drywood infestation is widespread or unreachable: colonies evidenced at multiple points of the structure, galleries running into framing nobody can access, or an escrow report mapping scattered activity. Fumigation is the one method that reaches every colony at once, including the ones no inspection can see. When spot treatment honestly covers it, you will be told that instead; see drywood treatment for that fork.

Plan for roughly two nights and three days: tenting and release day, exposure day, then aeration, certified clearance testing and re-entry authorization. The exact schedule is confirmed when the job is booked, and re-entry happens only after clearance readings, never on the clock alone.

You get a written prep list well in advance: food and medications sealed in the supplied bags or removed, plants out, pets and people out for the duration, gas service coordinated, access points unlocked. The crew walks the list with you rather than leaving a pamphlet.

No. Vikane (sulfuryl fluoride) is a true gas: it penetrates wood and voids during exposure and then aerates completely out, leaving no surface residue, which is why dishes and clothes need no washing afterward and why bagging is limited to consumables.

It eliminates everything in the structure on fumigation day; it leaves no barrier against future swarmers, and no honest company claims otherwise. That is why the close-out conversation covers prevention: sealing attic vents and raw wood, borate treatment where access allows, and the annual inspection rhythm that catches any new landing early.
