Okay, so I go to a Tech school where we have a greenhouse. We left it over the summer, and yellow striped army worms took over. They have gotten pretty big; and my teacher is at a loss of what to do. Is there a way to get rid of them? Because of a new district rule we cannot use chemicals in the greenhouse.

Bt, (Bacillus thuringensis) is death on caterpillars. It is organic and totally safe for humans and pets. It's distilled from a soil bacteria. Spray it thoroughly all over the plants and within 4 - 6 hours they are dead. Any real nursery will have some brand with Bt as it's active ingredient.
