What is a fumigation?
Fumigation is the process whereby
wood destroying pests are eliminated from a structure with the use
of lethal gas. A complete treatment with a fumigant reaches every
corner of the structure, including inaccessible areas, and the
fumigant kills every termite, even those that are not visually
detected.
Why fumigate?
Insects that feed or tunnel into wood
can seriously damage home dwellings and structures. Each year termites
or other wood destroying insects damage approximately 2 million homes.
Depending on the extent or location of the infestation, fumigation is
an effective control measure proven to eliminate certain infestations
of wood destroying insects.
How buildings are fumigated
The structure is completely sealed
prior to the inducing the fumigant. This process serves to contain
the fumigant within the structure so that it can penetrate wood
members thoroughly and eliminate the pests. The building will remain
sealed 4 to 72 hours depending on the specifics of the job (a typical
home will be covered 16 to 24 hours then aerated 8 to 24 hours).
Depending on the construction of the building, the doors and windows
may be sealed with tape and a plastic sheet, or more commonly, the
structure may be covered with tarpaulins. Warning signs are posted
around the building notifying individuals that the property is being
fumigated and to keep out. After the tarp or tape is removed, a
professional fumigator will aerate the structure by opening the doors
and windows.
Fans may also be used to air out the building. Once the dwelling has
been thoroughly aerated, the fumigator is required to measure the
level of any fumigant remaining in the living space to ensure it is
below the EPA approved concentration for safe re-entry by the
occupants. Extremely low levels of fumigant can remain for a short
period of time in dead air spaces. This can occur between walls and
inside cabinets, as walls are made up of porous material. The small
amount of fumigant in these areas will continue to dissipate for a few
hours after the fumigation has been completed. The levels, however,
are well below the established safe re-entry concentration.
Your property/building will not be cleared for re-occupancy until it
is safe to enter. How do you know it is safe to return? The fumigator
will post a notice on your structure indicating the day and time for
safe re-entry. Structures can be occupied only when the concentration
of fumigant is 3
parts per million or less (this represents a considerable margin of
safety).
Safety
Precautions by Homeowner
Discuss the treatment program with us in advance so that you fully
understand what will be done and what you need to do. Carefully follow
the instructions you are given about what items are to be removed from
your dwelling. Stay out of the treated structure until it is cleared
for re-entry. You may wish to increase the ventilation period.
Because our quality control standards are high, we select only the
highest caliber technician. Our goal is to deliver a professional
fumigation to our clients. We look forward to serving you. |
