Bretsmom from St Louis, Mo writes

Can BTI Mosquito Dunks be used in a French drain and will it hurt the lawn grass if overage of water occurs?

Answer:

Yes, BTI Mosquito Dunks can be used to treat standing water that builds up in french drains. You will need to anchor the dunks inside the drain with a string to keep them in place. BTI Mosquito Dunks will reactivate when they get wet and last for 30 days. There is no harm to the lawn if overage occurs.
