Thrips are tiny insects that can be either red, black, yellow, or dark brown. Thrips can cause serious damage because they have been known to carry viruses along with extracting the plant’s fluids causing leaf drops and failure with flower bloom. To control thrips prune or remove infected plant parts including the flowers. The use of neem oil or insecticidal soap will also eliminate them.
Leaf Miners will do damage the same as earwigs, control these garden insect pests the same as you would earwig. The use of insecticidal soap along with the removal of infected leaves will give good results.
