    Default Sawdust Under My Plant Mount

    Yesterday I was a little disturbed when I found sawdust under my grapewood mount for one of my plants. I cleaned up the sawdust, but more appeared this morning, ugh. I didn't see any bugs/worms, but I sure did see evidence of them via the sawdust.

    Short of tossing the mount, is there anything I can do to get rid of this pest without killing the plant? The plant is pretty well established and I wouldn't want to remove it from the mount unless I have to. But if I can't get rid of this nasty little bugger, I'll have no choice but to toss the wood.

    I think it is a grub of a beetle. A sort of wood borer. I would look the grapewood over for the tiny tell-tales holes. If you find them use a caulk or crack filler and plug the holes the grub dies from lack of oxygen.

    I just got over this!! It's the larva of a wood Borer beelte. Mine was a "deathwatch" beetle identified from it's 'clicking' sound at night. I tried plugging the holes but they were just under the surface enough to still breath. I used the Bayer Complete Rose & flower insecticide. 2 applications worked like a charm.

    You can just soak the mount for a while to drown the insects, no chemicals needed. If you fear eggs that might hatch, soak again the following week, and then another week later.
