Ok, so lets get started with tomato hornworms. Now for most people, the tomato hornworm is just a weird sounding bug, completely insignificant. But since Im assuming you knowingly and determinedly found this page, I think you know at least something about this fun pests.
So what do you need to know about tomato hornworms and tomato hornworm control. First, these pests are often found throughout all of North America. As the name suggests the tomato hornworm commonly targets tomatoes as its primary source of food. However, this is in no way an exclusive diet. In fact, they have been known to chow down on potatoes, peppers, eggplants, and tobacco plants. Now please dont confuse my words, thinking that the hormworms are actually consume the fruit of the plant. No, they do not enjoy a nice vegetable salad the likes of which you are accustomed to. Instead, they consume the leaves and stems. In rare instances, very rare instances, they have been known to nibble on the fruit.
Ok, so what exactly are these organisms? Basically, tomato hornworms are massive caterpillars. They are predominantly green, with other colored stripes criss-crossing their back. At full maturity, otherwise known as being a moth, adults can have up to 4-5 inch wingspans. The colors of these organisms change dramatically from their younger selves. The moths are a grayish brown, a direct result of their change in surroundings.
Unlike many other similar pests, the tomato hornworms are much larger. Thus the hand-picking technique is actually fairly effective. For this method, all you do is walk up to the plants, look for a few hornworms, and just grab them. Pretty simple, huh? And for all those of you who get a little queasy at the thought of touching these pests, just buy a pair of gloves or man up. Either way, you can get the job done fairly easily.
If they are just too numerous or you dont want to spend your time picking them off one bug at a time, you can always turn to pesticide. These chemicals should be short-lived and preferably natural if at all possible. Of the chemically-driven options, this would be the least harmful the the surrounding environment.
If all else fails, you can always resort to insecticide. This method normally involves very caustic and lethal chemicals that kill most everything in their sight. This method should only be implemented if the tomato hornworms are overwhelming the plants and are incurring significant damage. This is a very effective method.
