I have a lot of tiny yellow (bugs?) on milkweed. Are they harmful to the milkweed or other plants near by plants?

These are oleander aphids, a very common problem pest found on milkweed. They typically do not spread to other plants so there is no need to be concerned about that. Milkweed does seem to tolerate this infestation. Please see the following information on our website that also talks about control if you feel that it is necessary.
