> Why should cosmetics matter more than the bees?

Xerces made this point in their report last year:

* Residue levels in some ornamental plants far exceed the estimated level of lethal concentration (LC50) which suggests that cosmetic use of neonicotinoids poses high risks to bees.

* Legislators, regulators, and municipal leaders across the country should consider banning the use of neonicotinoid insecticides for cosmetic purposes on ornamental and landscape plants (as the ban now in force in Ontario, Canada). Approved application rates for ornamental and landscape plants, as well as turf, are often much higher than for farm crops.

* Until a ban on cosmetic use of insecticides goes into effect, all neonicotinoid products marketed for non- agricultural use (e.g., homeowner products) should have label restrictions that limit application times, and reduce application rates on plants visited by bees.
