Apr 12, 2012 – Pyrethroids Changes

QUESTION:

You have referenced label changes to synthetic pyrethroids recently in your articles. Can you summarize these changes?

ANSWER:

You can find the complete lists of the label changes and the interpretations of some of them by EPA on PestWeb in the “Industry / PestWeb Features” resource. This has changed slightly since we first put it up on PestWeb as new information and interpretations came along, but the basics are the same. NPMA also did a recent Webinar on this important subject and that is available on their website. 

The basics of the changes are that they are intended to further minimize the ability for synthetic pyrethroids to leave the intended application site and to get into local aquatic sites – streams, lakes, etc. and since rain gutters flow to creeks this is a big part of the new labeling. Broad applications to exterior surfaces that are likely to be contacted by rain or irrigation are, in general, now prohibited, except for applications to surfaces where the material can immediately be absorbed, such as soil and turf, and will not then run off the surface. But, our ability to spray entire surfaces of sides of structures is now prohibited. You can continue to treat a band around the base of a structure up to 3 feet above grade if the label allows that, and can continue to treat entire undersides of eaves if the label allows treatment under eaves. But, other exterior surfaces are limited to spot or crack and crevice treatments. 
An important addition to the labels of ALL pyrethroid products and formulations is the statement “do not make applications during rain”. This is important because the use of granules during rainfall or if rainfall was imminent has been a standard practice. This will no longer be permitted and very few alternate products are available for this. 
There also are now specific new requirements for posting and notification for Termite Pre-treatments, requiring that the PMP work with the contractor of the site to be treated to ensure the site is covered with plastic sheeting following the treatment if rainfall is to occur within 24 hours, as well as prohibitions against treating within certain distances of aquatic sites or during specific wind velocities.
