If its not one this, its another. I'm getting kind of fed up with this one plant. I think I had an aphid problem, but when the pest control people came to spray for the bagworms, it looked like they were all gone. I finally had time today to go out and trim the hedges and that's when I notice all these guys {and I still have no FLIPPIN' clue what this plant is >.<}. I didn't trim it after I saw these guys, cause I didn't want to do anything that might harm the plant. The black stuff used to be green, so I'm hoping it means they're dead. *crosses fingers* And then I'm putting stuff away and out of curiosity I took my clippers over to this tree that hasn't grown in months to see if it was still alive only to notice these little insect houses all over the branches! Here are some pics: Any help on identifying the tree too would be a BIG help. They have tiny little holes in them too. HELP! Please?
