Some chemicals can be particularly toxic to aquatic organisms, wildlife and some important ecological insects such as dung beetles when used without reading the manufacturers label. Do not allow chemicals to enter water runoff, for example into storm drains or drainage ditches that could enter dams, water courses or surface water. Avoid treating animals with sprays in windy weather, as spray drift could cause safety risks and off-target effects. Be particularly careful when mixing concentrates and make sure all manufacturer label and safety directions are followed. Pour-ons and injectables also must be used according to the manufacturers label and directions.
