Help me plz

What kind of bugs?

If you havn't got a camera we need a much better description, what they look like, size, location, leaf condition etc so we can help you save them.

they too small six legged or 8 i can only see the once that walking on the white miller

Ya man we need a better description. Neem oil treats a wide variety of pests and so does spinosad, so if you havent tried either of those give it a shot. Also if you are killing them each time you spray you may have a larger problem outside that you are going to need to take care of.
