Whole Structure Fumigation vs. Spot Treatment
Advantages of Whole-structure Fumigation
• 100% Elimination of Drywood Termites
• Administered by Trained, Knowledgeable Fumigation Experts
• Backed by Unparalleled Service and Support
Disadvantages of Spot Treatments
• Spot treatments do not eliminate unidentified termite colonies
• Drywood termites that survive can re-establish a new colony
• Homeowners may have to pay for multiple spot treatments over time to
control drywood termites
• Some treatments may require drilling which can potentially cause additional
damage to a home
The Five Steps of Fumigation
1. Sealing the Structure
After a series of preparatory steps, your fumigator will completely cover
the structure with a number of tarpaulins that are joined together into
a gastight “bubble”. This bubble is sealed to the ground around the exterior
of the structure with weights filled with sand or water. One or more
hoses through which the fumigant will be introduced are run from the
interior of the structure to the exterior fumigant release point. The
doors of the structure are then locked with special locking devices and
warning signs are attached to each side of the structure.
2. Fumigant Release
The next step is the release of the fumigant into the structure. The
fumigator uses a special calculator to calculate the amount of fumigant
that must be released to kill all of the termites. Just before the fumigant
is released, a special warning gas (chloropicirin or tear gas) is released
into the structure. Anyone trying to enter the structure unprotected
would be warned to leave by the smell of the warning gas and the tearing
of their eyes.
The length of time the drywood termites are exposed to the fumigant is
also calculated. The length of the exposure can vary based on several
factors such as the lowest temperature within the structure. Most exposure
period are 20 to 24 hours in length.
After the exposure period is complete, the airtight bubble is opened
at several points to allow the fumigant to escape. Movement of the fumigant
out of the structure is aided by exhaust fans. The tarpaulins and weights
around the structure are also removed.
After a sufficient period of time, the fumigator will test the air within
the structure for the fumigant using a sophisticated instrument able
to detect the fumigant at extremely low levels in the air. Only after
the structure has effectively aerated and is certified for you re-entry
will you be allowed to re-enter the structure.
• Access to property including garage. We must have keys to structure prior to fumigation. This includes garages and
locked bedrooms or closets.
• Signed Occupants Notice and Pesticide Disclosure. This
form must be signed and in our possession prior to the fumigation.
• Food must be double bagged or removed. This includes items in the refrigerator. Please read our bagging instructions
for further information on what to bag and not bag.
• Electricity must be on. Fans and monitoring devises are used during the fumigation which require the
use of electricity.
• All animals must be vacated. This includes fish. Outdoor cats are recommended to be taken away from the
fumigated structure. Dogs may not be left or leashed inside the yard.
• House plants must be removed. Plants left in a fumigated structure can die from exposure to the fumigant.
• Gas must be shut off by the Gas Co. prior to fumigation. We will schedule to have your gas shut off the morning of the fumigation. You
must call to have your gas service restored. Gas Co. 800-427-2200.
