John inspects this colorful caterpillar and soon realizes it is the dreaded hornworm. This pest is the Tobacco Hornworm, as identified by his 7 stripes, and is capable of decimating whole tomato or pepper plants in no time! Nash and Katrina spent a morning picking them off by hand, but it's a challenge because of their incredible ability to blend into the foliage. An organic solution will be used to spray the plants with bacillus thuringiensis (BT), a natural and safe microbial pesticide.
