Non-Chemical Management
- Keep trees healthy to enable them to tolerate some damage.
- Prevent injuries which may attract carpenterworm moths to trees.
- Probe tunnels with a sharp wire to kill larvae (when practical).
- Apply beneficial nematodes (Neoaplectana carpocapsae or Steinernema feltiae) into tunnels to kill larvae. Fill tunnels with nematodes in water, then plug holes and wait about a week. It may be necessary to treat tunnels again if plugged holes are reopened by surviving larvae.
