For the most safety for bees and other pollinators, you should apply a systemic product such as Bio Advanced 12 Month Tree & Shrub Insect Control Landscape Formula after any flowering plants have bloomed and the petals have fallen in the spring. For plants that do not flower, you could treat in late fall on larger trees so that you get quick uptake with new growth in the spring.
