PYRETHROID LABELING CHANGES
To reduce ecological exposure from
residential uses of pyrethroids, EPA has
instructed registrants to revise the "Environmental
Hazard Statements" and general “Directions for
Use" for pyrethroid pesticide products used in
non-agricultural outdoor settings. These label
statements will reduce potential runoff and drift
that can result from applications of pyrethroid
end-use products by both professional pesticide
control operators and residential consumers
in residential, commercial, institutional, and
industrial areas. The label statements spell
out good stewardship and best-management
practices and clarify how these types of products
are intended to be used. The label direction
changes vary according to the formulation of the
product, that is, the instruction on a granular type
product is not the same for a liquid type product.
So be sure to follow the all important and
universal requirement “Read The Label First” for
each pesticide. The effective date for registrants
to make these label changes is June 4, 201 0 and
therefore affected products with the new labeling
is already in the market place.
Over 2,000 end use pyrethroid products are
required to have the revised labeling. Pyrethroid
products that are affected include those
with allethrins, cypermethrin, tau-fluvalinate,
permethrin, resmethrin, smithrin (d-phenothrin),
and tetramethrin. 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.
Actions for Consumers to Reduce Spray Drift
and Runoff from Pyrethroid Pesticide Product
Applications:
✓ When applying pyrethroid pesticides around your
home, follow these good stewardship practices to
protect water resources by reducing runoff and
spray drift.
✓ Only apply the pesticide directly to the treatment
area.
✓ Be mindful of the location of storm drains,
drainage ditches, gutters, or surface waters during
a pesticide application. Apply the pesticide in a
manner that does not allow the product to enter
these areas.
✓ Applying pesticides during calm weather
conditions, when rain is not predicted for the next
24 hours, will help to ensure that wind or rain does
not blow or wash pesticide off the treatment area.
✓ Rinsing application equipment, such as watering
cans, low pressure hand wands, backpack
sprayers, etc. over the treated area will help avoid
runoff to water bodies or drainage systems.
✓ When applying granular products, sweeping
any product that lands on a driveway, sidewalk,
street, or other hard impervious surface, back
onto the treated area of the lawn or garden will
help to prevent runoff to water bodies or drainage
systems.
✓ When watering treated areas, refer to the
watering-in instructions on the label, and ensure
you do not water the treated area to the point of
runoff.
