| Are you using the spray or the granules? The important thing about the Bayer systemic spray is to apply it when the bees are not active, i.e. either very early in the morning or very late in the afternoon. The wet spray will kill bees. Once the spray is dry (within an hour or less) and absorbed into the plant the bees are safe. This information is from the label (by memory). If you're putting the granules on the soil, it shouldn't affect the bees at all. I've used the spray on lilies for several years, and the bees have been fine. Claire |
