Hark! I may have found something.

Today I noticed that hornworms had eaten almost all the leaves of what had been a great bush of datura. I went out and looked but couldn't find one worm.
I went back inside the garden and got to coil hose in the greenhouse an began to water the datura over the fence.
That's when I noticed the flicking. I watered it again and again the plant seemed to flick the water off.
I went out and looked closely, sure enough it was a hornworm big a round as your thumb. I clipped of the stem into a can and took the coil hose from the greenhouse as far as it would go and began watering the tomatoes. Each time a hornworm got wet it would snap to get the water off. I took a can full of worms to the chickens.
Can I patent this? Can I huh?

Try this if you didnt already know it. It's new to me. Let me know what you think.

So you spray them with water and they blow their cover? Great discovery!

Very cool discovery. My chickens are afraid of them and will not eat them. Chickens.

Wow, that is a great little discovery. I will remember that next time I have one I can't find. I spend a little time each day looking over my tomato plants, checking for the tell-tale little "grenades" that the horn worms leave. I wonder how large a horn worm can get? I have seen them as large as my thumb, but not a man's thumb. I tend to not want to pull them off by hand when they are bigger than my hand.

I have gone out at night with a black light to search for hornworms. The colors that blend into the plants during the day "glow" under my light. I've heard regular flashlights work just as well, but. . . I get to use the light.

I have been bitten by a hornworm or two so I take clippers and cut the smallest part of a branch off with the worm before tossing it. Sometimes I slice into the worm and leave it.

I hand pick them and get creaped out when they curl up and try to get me. I toss them onto the golf course, and hope that the birds eat them.

UGH, nasty worms. Cool discovery. Now I want a black light too! LOL
