If the chips came from a wood chipper (instead of a grinder) then EAT won't survive the small chip size (one dimension <1").
If the chips are larger you can also cook the critters by putting a layer of black plastic over them and seal the edges with a layer of dirt. The chips need to be in direct sunlight for a good amount of the day for a couple of weeks to guarantee total mortality.
