Safe for chickens. Not safe for beesIt's labeled for use on chickens too.

Natural Pyrethroids
Pyrethrins are a mixture of substances and are extracted from the oil of a type of chrysanthemum (Chrysanthemum cinerariaefolium extract). Pyrethrins are often in aerosols to combat various types of insects and may also be used in (organic) agriculture. The substance piperonyl butoxide is often also added to enhance the effect. Piperonyl butoxide itself is not an insecticide but ensures that pyrethroids are broken down less quickly in the body of the insects. "Natural" does not automatically mean good or safe. Natural pyrethrins are less harmful to mammals and birds than many synthetic pyrethroids, but still very harmful to fish and beneficial insects such as bees.
