Use
Integrated Pest Management (IPM) to Minimize
Pesticide Use in Construction
Pesticides
used to safeguard an unprotected building over its
life can be a major source of toxic release. Instead,
use mechanical insect controls such as concrete,
sand barriers and sheet metal foundation shields
wherever possible, instead of toxic wood treatments,
fumigation and residual pesticides in perimeter
soils. Use termite-resistant outdoor lumber substitutes
such as recycled plastic lumber and fiber-cement
products.
Provide
maximum allowable clearance of wood materials from
soils, and build inspection openings into all concealed
foundation spaces. (Most termites must build tubes
to reach wood that is more than about 12 in. above
ground in exposed locations.)
Use
pest-resistant landscape materials and naturally
pest-repellent plants. These steps often cost more
than spraying at the outset, but are non-toxic,
semi-permanent, reliable solutions, which pesticides
alone are not.
Cautions
- Pest
control details should be verified by a specialist
in IPM practices.
- The
contract should specify limitations on chemical
pesticide spraying acceptable to building authorities
and the owner.
