#11 Flea Beetles

Flea Beetles often target young plants and seedlings. They are tiny, jumping from plant to plant like fleas. An infestation causes reduced plant growth, and in severe situations, plants might die. You can use diatomaceous earth and neem oil that are effective control methods.

#12 Cutworms

Cutworms live in the soil and are particularly dangerous for young seedlings and plants. At night, they chew through the stems rapidly, often severing plants at the soil line. To reduce them, make a collar around the base of your basil plants with aluminum foil or cardboard to protect the stem from cutworms, and then push the collar one inch into the soil and leave a minimum of three inches above the soil.

#13 Grasshoppers

Grasshoppersfeed on the foliage, buds, and stems of basil. The nymphs feed on the leaves, causing holes everywhere. As the pests grow, they’ll destroy the foliage. You can grow some plants that attract birds, they will help you get rid of grasshoppers. If infestations are serious, let’s spray insecticides.
