“It’s difficult to control peach tree borers with pesticides because the destructive larvae are deep within the tree where pesticides can’t reach them. However, the biological pesticide Bt (Bacillus thuringiensis) or beneficial nematodes can be injected into the borer holes with a needle-less garden syringe.
