@#$%^&* hornworms!!!!!!!!!!!!!

My tomatoes & peppers have been absolutely loving this hot rainy weather we have been having, so in the past day or so I was delighted to find that all my plants were in full bloom with itty bitty veggies. Today, I went to grab a cucumber for dinner, & to my horror everything had been eaten down to the stalks!!!!!!! Nothing I have tried works on these suckers. Anybody out there got any ideas? I would welcome any input, believe me. On another note, my Old Shale Shawl is turning out just beautiful. My son is getting ready to head to the windy soon!!!!!!!!!!!!!!!!!
