Defeat worms with wasps.

Countryside: Please be advised that trichogramma wasps are a very good control for army worms as it took just two seasons to eradicate the worms from an entire orchard and farm and into surrounding areas as well (November/December issue, "The Great Army Worm War"). We won our war with less overall effort on a much larger scale. The wasps could be purchased from nursery supply companies under beneficial's or beneficial insects. I would start looking for them early if you had any at all last year. They are sent fairly early in the season as they need to hatch out. Perhaps Countryside could locate suppliers?--David Shepard

Trichogramma Wasps lay their eggs in the eggs of the army worms, which kills them. There are a number of plants that will attract the wasps, including: common yarrow, dill caraway, coriander, Queen Anne's lace, tansy, parsley, pennyroyal, fennel, lemon balm, and Cosmos white sensation.

There are numerous sources for the wasp eggs including: Planet Natural,, 888-784-1722; Arbico Organics, 800827-2847.
