|My son brought home some green bean plants from school that they were growing. We planted them outside and they were doing well. Then I noticed these little black bugs once the bean pods started growing. i have sprayed them with a liquid insect killer, seven I think, but they are still there. What can I do? I think they are going to ruin the green beans.

|The most common insect problem with green beans is the black aphid. Insecticidal soaps will control them but repeat applications are necessary. Or, you can hose them off with plain water. Even if you kill off the current generation, lots more will appear so hose them off or spray them with insecticidal soap whenever you see them congregating on the new growth. Best wishes with your beans.
