Heard on the news today the EU has outlawed this as their research proved it was a major cause of their bee declines. Also heard every nursery plant we buy usually is treated with this and it stays in plants for years even in their nectar..
I for one like to use Neem oil and soap. Hope we can get a handle on this or the future generations will not be able to eat a blueberry, raspberry, or any other plant that needs a bee.
