Looks like aphids. Best solution is to get some ladybugs. They love to chomp on aphids.

Wash the plants under the faucet and they'll go down the drain. Or, hose them off gently outside. Handpick if necessary...that's part of the zen relaxation of gardening. :)

Thanks... I have been handpicking them... and dont mind doing that but will try rinsing them (why is it my kids find ladybugs when I don't need them? :) )

I agree that they are red aphids and they are sucking the good from the plants. A forceful spray with cold water helps or try insecticidal soap. Mix with water as per package instructions and spray the plant. The soap will also kill any eggs and it is completely safe. Then watch to see if you've missed any.

Did you find any ants among the aphids? Typically, ants act like dairy farmers and use the aphids as "milk cows" moving them around to good feeding locations and mil;king them of the sweet juices.
