Bean plant problems

Bean plant problems

I've been trying to grow pole beans these days, and the emergence rate of my seeds is terrible. I sprayed with beneficial nematodes last week; that has been helpful in the past. I got up close today and saw swarms of tiny, white insects. They are too small to discern a shape, they are just dots. They are swarming on the soil around the few said beans that came up. Are these mites? Would pyrethrin solve my problem? Thanks for any ideas!
