ROOT APHIDS

I have been battling root aphids. I have watered with nematodes twice in two weeks. Now the aphids are walking around on the floor but they are still in the root zone. I set a pyrethrum fogger to take care of the exposed live aphids. I am about to water the soilless planting mix with Botanigard. Then in two days add more nematodes. Do you have any suggestions?
Most of your efforts are effective. Beneficial nematodes attack most soil dwelling insects. Use pyrethrum as a drench, rather than as a spray or a bomb. This way it gets directly to the insects. Botanigard contains spores of Beauveria bassiana strain GHA. This fungus attacks soft-bodied insects, causing their deaths. It can also be applied as a drench. All three of these treatments can be used concurrently to attack the pests.
Botanigard is available in an organic formulation called sold under the name, Mycotrol A.
The pesticide "Ed Rosenthal's Zero Tolerance" is an herbal mixture that is often used for root pests. It is also effective.
