Kids & Pets
People and pets may reenter the treated area after it has dried.
To protect the environment, do not allow pesticide to enter or runoff into storm drains, drainage ditches, gutters, or surface water. Applying in calm weather when rain is not predicted for the next 24 hours will help ensure that wind or rain does not blow or wash pesticide off the treatment area. Rinsing application equipment over the treated area will help avoid run off to water bodies or drainage systems.
The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Application around a cistern or well may result in contamination of drinking water or groundwater.
