This is an issue that makes me so emotional, I can hardly restrain myself to write coherently about it, which is why I am going to refer you to an article on the subject on the Xerces Foundation website.
Please read this article and avoid the pesticides on the list AT ALL COSTS. These pesticides accumulate in plants for up to six years and also build up in the soil. When people use them on lawns to kill European chafer beetle larvae they kill non-stinging ground nesting bees. Please spread the word. Make signs. Raise hell! Send your protest photos to me: beespeaker(at)gmail(dot)com.
