Anyone here using urine?

Hi Richard. I noticed you have experience dealing with Peach Tree Borer. I am trying to avoid chemical pesticides, but will break that code to save my trees if I need to. Do you have any advice for how to tackle this? I have tried nematodes, but I think its too dry here for them to thrive. I did some neem oil, spraying monthly, but haven’t yet tried the direct application via full concentration with paint brush. I’m looking for the next level of wisdom here. Trees are getting hammered.

Cheers
