Andy,
In Michigan there was a local problem with pine shoot moth damage. My trees
never had any sign of infestation or damage.
The one factor may have been an oil spray done in the late fall and
repeated in early spring. Perhaps this smothers the eggs and prevents the
problem?
It might be worth a try.

Like Tim, I've experienced some shoot tip moth damage (not in my bonsai
nursery, thankfully) on pines in my pre-stock area in the yard. I've never
read of any way to prevent them from laying eggs in the candles, nor even
what season that generally occurs. Can anyone suggest good measure(s) to
take against infestations and also cite the season the egg laying is going
on? Thanks in advance.

Kind regards,
Andy Rutledge
