If they are that big, pick off by hand. No chemicals required.

Army worms...they usually appear in droves so keep a good eye out for them and remove them when you find them. Best time to hunt for them is in the evening hours or very early a.m. The birds like them; you may want to consider tossing them into the bird bath. If not, just drop into a can of soapy water to drown efficiently.

Oh its just that simple? Sounds good to me. Thanks
