Neonics have been implicated in the die-off of bees.  Are you doing everything possible in your garden to protect all pollinators?  This is a downloadable handout explaining important steps for a garden healthy for bees.

XERCES Society is a rich resource for information.

   "Neonicotinoids ("neonics") are a group of insecticides used widely on farms and in urban landscapes. They are absorbed by plants and can be present in pollen and nectar, making them toxic to bees. Four years ago there was uncertainty about the impact these insecticides were having on bees. Research published since then clearly shows how neonicotinoids are killing bees or changing their behaviors."

The most widely used garden insecticides are a class of chemicals called neonicotinoids.  The Center for Food Safety has provided this list of products that contain these harmful chemicals.

It's good to know the science behind how neonics work, and the environmental concerns. This fact sheet can be downloaded.
