How long after application will the product be toxic to native bees?
The active ingredient in Talstar PL granules is bifenthrin, which is a residual non-selective insecticide. The residual could harm non-target insects like bees if they were to come into contact with enough active ingredient for several weeks after application. However, since this is a granule insecticide that is applied directly to the ground and then activated with water, it is very unlikely any pollinators like bees would actually come into contact with the treated areas. The bigger risk would be from sprays, so we recommend applying sprays in the morning or evening when pollinators are less active, as well as avoiding spraying blooming plants to reduce risk to pollinators.
