Isn't it late for peach tree borer larvae?

I just discovered another peach tree borer today. I thought it was kind of late for that kind of thing. So far only my NJ-252 has been infected. I cleaned at least one out this spring and now noticed more damage and a live larva.

I can't find much information on how many eggs a moth lays either. Should I expect to find more than one at a time?

So much disagreement about treatment on the web! I'm going to put "old fashioned" naphthalene moth balls around the base and see what happens.

I was just wondering if this is a normal thing this time of year.

I find them this time of the year regularly in NY.

I've found my first borer in this time of the year a few years ago. I've not seen one since.

I've used moth balls but am not sure they are helpful or not since I also spray the trunk with Triazicide a few times a year.

In my area, August is the high point of adult mating activity, and that is when we spray for them. That 's when they lay their eggs and the larvae enter the trees.
Moth balls don't prevent any of this from happening and are really a waste of time.

I find them year round more or less. Early spring I find the best time to dig them out, they are big enough to be able to track down but most of the damage has not happened yet.

This spring I microwaved tanglefoot to get it fluid and painted it directly on the lower 6" of my trunks, to the ground level. I haven't seen a borer since then. Note I dug out 20-30 of them by hand before this treatment. I also treated only 5-year and older trees, the younger ones I used tangle trap instead (less caustic).
