Killing the Monster Moth Larva

This caterpillar was dying at our son's house. It was quite large and I am still not certain what kind of moth it would have made. It was almost as large as a hickory horned devil but the colors were all wrong. But possibly that was due to the fact that it was dying. The yellow spots are the sphericals that it breathes through. But the white spots are the eggs of a parasitic wasp that consume the caterpillar as they develop.
