I just dug up my back yard to put in a new lawn and I came across a couple of dozen of these larva buried throughout my back yard.
I'm wondering if this is what's killing my vegetable garden and fruit trees.

They suggest no action needed unless you have more than 2 - 3 grubs per 6" x 6" space. 1/4 square foot.

EricNon-chemical controls: Milky spore disease (Doom, Japidemic) is a slow acting bacterium used to control the grubs of the Japanese beetle. It is not intended for use where grub populations are high. Once treated, however, bacteria are supposed to cycle in your lawn as new grubs die and release more bacteria. Research data are inconclusive on the effectiveness of this material.
Nematodes are becoming available for white grub control. The most promising results to date have been with Heterorhabditis bacteriophora (the so-called 'HB' strain) at a rate of at least 1 billion per acre or Steinernema glaseri at a rate of 2 billion per acre. It is critical that the soil temperature be close to 70o F and that you water these in with 1/4 inch of water. Several studies have shown very good control; others have demonstrated poor control. Research is continuing and product availability is limited. For additional information see the web site: https://www.oardc.ohio-state.edu/nematodes.
Step 5. Long-term suppression:
Since grubs are not found as often in shaded lawns, plant shade trees and select shade-tolerant grasses for long-term suppression (see URI's Sustainable Tree and Shrub List).
