go out and get a product called "BT Wormer". It's one of those solutions that you mix a couple of ounces of it to a gallon of water. Spray it on your ladies once a week. It will deal with worms(li'll green bastards,green catapillars, and the brown catapillars that sting or bite)& catapillars. I started using to stuff two years ago and haven't looked back! Don't wait to pick this stuff up, it will work! If you are an organic farmer, like myself. you'll have to look elsewhere for help. Neem, Peppermint soap,etc.,etc...
Once I truly gave way to 100% organic farming , BT Wormer was no longer an option.
Good luck
