Bt will work on hornworm quite well but if they're a recurring problem you might use on on a ten day or two week cycle so you get them while they're small before they do any bad damage. The big ones can strip a plant in no time.Carol Dee said:Will it also work on hornworm? We had a BIG problem with them in our tomaotes and eventulluy the sweet peppers. Nasty things. ugh.thistlebloom said:BT is bacillus thuriengiensis, a bacterial disease that affects insects. Hoodats right about it working on your bagworms. If you garden organically it's a good "natural" insecticide to use.Smiles said:Thanks but what is BT?
I think you can find it at feed stores and some hardware stores, it's pretty common.
