I'm looking for a beneficial predator/parasite for hard-bodied (armored) scale. I understand that lacewings and ladybugs will consume the soft-bodied scale. Do they also consume the armored type? Are they effective? Against the adults, too, or just the crawlers/babies?

Any recommendations?

This scale is oval-shaped, transparant, and is on clumping bamboo (B. multiplex).

Thanks!

Leslie
