An Oregon lawmaker is seeking to restrict home gardeners' use of some pesticides suspected of killing bees in Portland and other cities last summer.
Portland Rep. Jeff Reardon, a Democrat, plans to introduce legislation next month to add four pesticides to a restricted use list.
The Oregonian reports that would effectively force home gardeners to hire professional pesticide applicators or use alternatives.
Reardon says the proposal would protect bees that provide pollination for flowers and crops.
Oregonians for Food & Shelter's Scott Dahlman says there's no evidence that home gardeners' use of those pesticides caused mass bee deaths.
The measure would apply to four pesticides that belong to a class known as neonicotinoids and are found in some garden products.
