Bayer Advanced 3-in-1 Insect Disease & Mite Control Concentrate is toxic to bees while the application is wet. It is recommended that you do not apply this product while bees are active or to flowering plants. The tau-flauvinate is the residual topical insecticide and it is non-toxic to bee once dry. It would not harm birds when used as directed. It is recommended to apply when they are not in the area and there is enough time for treatment areas to dry before they are. Please refer to the label for complete application instructions.
