"Honey bees weren’t affected by the [neonicotinoid] seed treatments. But wild bees were affected, and in a big way.... In this study, no mason bees (Osmia bicornis) began brood cells in the seed treated fields. None."
Further, any chemical - especially that one you spray on your grass in town - kill bees. They are acutely sensitive to ANY treatment. Since they visit a wide area (miles) your lawn treatment affects bees all over the neighborhood.
