Both Mountain Pine Beetles and IPS Beetles have invaded the pine trees, Ponderosa and others, of Colorado. As a "Dirt" subscriber, I need a good organic control for these pests in addition the Healthy Tree program.
Tree trunk goop enhanced with orange oil?
Trichogramma wasps?
Or something out of ye ole hip pocket to match the species and climate?
Many thanks.

As I understand it, one of the reasons these have become such a nuisance is there are a number of re-planted woods there where only one type of tree has been planted en masse and the result is a monoculture that unfortunately bceomes an attractive haven for the pests that target that tree.

Most pest bugs I know of will be run off with garlic tea, light amounts of orange oil (enough to run them off wihtout burning the foliage) or a combination of the two. As for Trichogramma wasps, I am not sure they target the beetle larvae the same way they do catepillars and such. I know a number of grubs that become other beetle varieties are vulnerable to beneficial nematodes and/or milky spore.

Good luck and keep us updated.
