|As you might expect, this required drilling will
add to the cost of the treatment.;
Although there are liquid termiticides available
for homeowner use, we do not recommend the "Do-it-Yourself" approach for
chemical control of termites for several reasons:
Some companies offer "spot treatments", i.e., they treat
only those areas of the house where termites are seen. Spot treatments,
except when done under an existing contract, usually carry a limited guarantee
(or no guarantee at all). With new/proposed contracts, any treatment procedures
that are not done according to state specifications must be noted on an
which you must sign as part of your contract.
Before you sign a service
agreement or contract, make sure that you ask about and that you understand:
Effective termite treatments require a significant volume
of termiticide. For example, a single-story house that is 1200 sq. ft.
(40' x 30') would require
112 gallons of diluted termiticide just
to treat the soil along the foundation walls (inside and out). The total
gallonage needed may exceed 150 gallons depending upon the construction
of the house. Few homeowners have the equipment to deliver this quantity
of chemical efficiently and safely.
Drilling and treating slabs, foundation masonry voids
and piers takes specialized equipment and training in order to avoid personal
injury or damage to subsurface water or utility lines or to the mansonry
The cost of the chemical is higher for over-the-counter
products. Let's use the example of chlorpyrifos (Dursban*), a commonly-used
termiticide. By some estimates (Lyon, Ohio State University), a Do-It-Yourself
treatment done according to label directions using Dursban Ortho-Klor
chlorpyrifos) would cost the homeowner about 2-1/2 times more money in
chemical costs than a licensed pest control operator using Dursban TC
(42.8 % chlorpyrifos).
