Green Horned Tomato worms are their proper name. I would call it a nasty, freaky, inbred Caterpillar thing that causes me to have extreme panic and paranoia.
I guess all the time I was growing up and enjoying those wonderful tomato's out of mom & dad's garden I had no idea that they were having to save their plants from these prehistoric looking creatures. I may have avoided planting tomato's had I remembered this little tid bit.
After spending the weekend at mom & dad's and going to the garden with my father, watching him pluck these things off his plants and step on them only to squirt a nice green liquid right out the end, I decided I better check mine when I got home. He informed me that if I did not remove them, they would kill the plants all together because they strip them bare of every leaf that they have given the chance. I kid you not, these things grow by the minute and they get as long as your middle finger and as big around as your thumb. They have this weird red horn thing that sticks up out of their butts and feet that clamp around the branch.
So I check Sunday evening, and to my most wonderful pleasure, there were none. Well...that changed last night, my daughter came running in the house with a complete look of horror on her face. She saw them, on MY tomatoes, happily munching away.

I think okay, be strong for her. I grab the pliers because I am NOT touching them with my bare hands and off we go. Well, off I go because she isn't stepping foot near the garden. I find them, several of them and brace myself. I am about to reach into tomato jungle and save my plants. One small problem, I couldn't do it. I tried and my arm would not go in there. I kept staring at them and increasingly getting sick to my stomach from pure fear. I just know in my mind they are going to jump off those plants and land on me and begin to happily munch away on me. I'm terrified and trying hard not to let it show. Then without warning, the tears come because I'm so freaked out and trying not to let my daughter see. I calmly walked back in the house and approached my husband. You have to get these off I say. He says now Hun, they aren't going to hurt you, just pick them off & step on them. I can't do it I say, I just can't. I tell him, your supposed to be my Knight in Shining Armour, get on the horse and help me!!!! So he picks them off one by one, there were 10 of them and I proceed to throw a rock on them and then step on the rock so they meet their demise.
As far as I know, the best method of extinction in the garden is to simply pluck & smash to get rid of them. I don't even want to go look tonight because I know there will be more there. I just want some nice red tomato's, why must I have these nasty things coming with them!
I'm usually not all weird about bugs & things like that but these worms just do me in.
