    • Ralph,

      Generally speaking both Tengard and Up Star ECTT&O are labeled for trunk sprays for pine beetles. But without knowing which kind of insect you are treating it is difficult to be really effective in treating an insect. Do you know what kind of pine borer you are treating?

      Hope this helps!
