Gnats are bad because of all the rain we've had. You can't get rid of them: DDT is not used anymore.
Best time for outside is early morning before hot and humid hits. The bites will continue until the morale improves.

Hi! Just moved to the Bethesda/Potomac area. We purchased our home in October. It's seems like the gnats here are ridiculous. Anyone have any luck getting rid of them.
