If there is one thing that characterizes worms, it is that they are elusive. First of all, if you want to locate them without losing patience, spray the tomato plant with water so that they twist and make it easier to see them.
Finish off the horned tomato worms by hand and cause casualties in your environment. If you disgust touching them, you can use tweezers to tear them from there, remember that they usually hide on the back of the tomato leaf. Take them off carefully!
