In a Feb. 26 email, EPA officially notified key stakeholders of its new outdoor use label language for pyrethroid, synergized pyrethrins and pyrethrins-only products and further announced the availability of a revised website explaining the issue. This is all information previously reported by NPMA and is the byproduct of a year-long effort by NPMA, in conjunction with ASPCRO and SFIREG, to expand the use of these products in outdoor settings, when making applications to surfaces not located above impervious surfaces.  
 
Pyrethroids and Synergized Pyrethrins--Label Language
Non-agricultural Outdoor Uses
"Do not apply directly to impervious horizontal surfaces such as sidewalks, driveways, and patios except as a spot or crack and crevice treatment. During application, do not allow pesticide to enter or run off into storm drains, drainage ditches, gutters or surface waters."
 
"All outdoor applications, if permitted elsewhere on this label, must be limited to spot or crack-and-crevice treatments only, except for the following permitted uses, if allowed elsewhere on this label:
1.    Applications to soil or vegetation, as listed on this label, around structures;
2.    Applications to lawns, turf, and other vegetation, as listed on this label;
3.    Applications to the side of a building, up to a maximum height of 3 feet above grade;
4.    Applications to underside of eaves, soffits, doors, or windows permanently protected from rainfall by a covering, overhang, awning, or other structure;
5.    Applications around potential pest entry points into buildings, when limited to a surface band not to exceed one inch in width;
6.    Applications made through the use of a coarse, low pressure spray to only those portions of surfaces that are directly above bare soil, lawn, turf, mulch or other vegetation, as listed on this label, and not over an impervious surface, drainage or other condition that could result in runoff into storm drains, drainage ditches, gutters, or surface waters, in order to control occasional invaders or aggregating pests."

6.    Applications to vertical or horizontal surfaces when surrounded by or directly above soil, lawn, turf, mulch, vegetation, or other porous surface, where runoff to surface water is unlikely to occur."
