Chewing Insect

The problem with chewing insects such as bug larvae or grasshoppers, beetles, caterpillars (too numerous to name) etc. is they move about and often are difficult to spot among the foliage, but if there are black dots on the foliage, it is the excrement of chewing insects. Chewing insects can be large enough to see with the naked eye, but they can be red, orange, green, brown, black, etc. so look closely and pluck off any you see and dispose in a bucket of soapy water as long as the infestation is not too extensive. If it is extensive, you can spray with an organic control for chewing insects recommended by your local garden center such as Bt or Spinosad, but follow application directions. Also show some of these leaves or this photo to a horticulturist at your local garden center for confirmation of the problem as well as recommendations for control but make sure it is formulated for vegetables.
