Atlanta Georgia this month, language is being added to labels of synthetic pyrethroid non-agricultural outdoor products that will greatly impact virtually all perimeter treatments and preconstruction termiticide applications. Aimed at mitigating  runoff and protecting both water quality and aquatic species, the new restrictions stem from research conducted by California researchers indicating that pyrethroid runoff from non-agricultural uses into nearby creeks was adversely impacting aquatic microorganisms. The U.S. Environmental Protection Agency (EPA) developed the new language in close consultation with California Department of Regulation (DPR) officials. 

Specifically, the language pertaining to “Restrictions for Residential Outdoor Surface and Space Sprays,” except for outdoor fogging devices, reads:

“All outdoor applications must be limited to spot or crack-and-crevice treatments only, except for the following permitted uses:

(1) Treatment to soil or vegetation around structures;

(2) Applications to lawns, turf, and other vegetation;

(3) Applications to building foundations, up to a maximum height of 3-feet.

Other than applications to building foundations, all outdoor applications to impervious surfaces such as sidewalks, driveways, patios, porches and structural surfaces (such as windows, doors, and eaves) are limited to spot and crack-and-crevice applications, only.”
