r><span></span><br><s Mary, and all. I'm curious about the use of neonicotinoids in mosquito zappers. I didn't know that it was used this way. That said, I've just been looking online and see all kind of household insecticide products that are using neonicotinoids. Here is a link to one list on the Xerces Society website. http://www.xerces.org/wings-magazine/neonicotinoids-in-your-garden/ By the way, shortly after posting my earlier message, I came across a newspaper article on a bee hive kill incident in Oregon on June 21. I'm not sure if the incident is related to an incident reported just below, but in that one, it was disclosed that a kill occurred due to misuse of a neonicotinoid pesticide on some linden trees around an apartment building. Pretty awful. I can see how easy it would be to immediately wipe out a lot of insects in an area if these products are misused. Here's a link to the story for anyone who is interested in this topic. http://www.statesmanjournal.com/story/tech/science/environment/2014/06/20/mass-bee-die-offs-reported-portland-area/11098907/ bev wigney Round Hill in summer On 6/26/14, Mary Macaulay <Marymacaulay@hotmail.com> wrote: > People are using them in mosquito zappers at well in recreational areas and > this is what brought them toy attention as I'm a keen dragonfly watcher.
