Frequently Asked Questions
1. Should I wash down
toys and other items in the yard at the time of the application?
While you can if you wish it is not necessary to wash the
items in your yard after the application.
Due to our low application rates any exposure from contact with these
surfaces would be low and pose negligible risks.
2. Should I cover the pool before the application?
It is not necessary to cover the pool before an application. The residues in
the pool will be very low and further diluted by the water in the pool.
3. Should I close the
windows and turn off my air conditioner?
The ULV vapor disperses readily and little movement of the
material into open windows with screens would be expected. However individuals with upper respiratory
problems such as asthma may react to ULV applications and closing windows and
turning off air conditioners is recommended to protect these individuals.
4. How long should I
wait before I let my pet out?
When the chemical is applied at the labeled rates there are
wide margins of safety for humans, dogs, cats and other mammals. Indoor pets my be "let-out"
immediately following the application.
Outdoor pets may be left outdoors.
5. How long should I
wait before allowing the children to enter the yard?
The ULV vapor disperses very quickly after the
application. However, individuals with
respiratory problems such as asthma may react to ULV application. People with these health issues may want to
wait an hour before resuming outdoor activities in treated areas.
6. When can I let my
horse or other animal graze on the grass again?
While, there is no requirement to remove foraging animals
from the site. We recommend that if
possible the animal be removed from the area while the application is
occurring. The animal can be returned to
the site shortly afterward. Any feed or
water should be covered.
7. How quickly does
the chemical break down?
Sumithrin breaks down primarily through exposure to
sunlight. According to the World Health
Organization, residues of sumithrin on certain plants and soils showed a
half-life from less than one-day to 1-2 days, respectively.
