Article: There are different types of insects that can be problematic in the garden, including ones like caterpillars and beetles that chew holes in leaves. These types of bugs can cause a great deal of damage to plants, so you should take steps to get rid of them. Along with using insecticide to treat caterpillars and beetles in the garden, you can also remove them by hand. Pick the bugs off the plant with your fingers and drop them into a bucket filled with soapy water. White, yellow, or brown discoloration on leaves could indicate that your garden is infested with bugs like mites or thrips. Both of these insects suck juices from plants and can cause leaves to discolor and die. When treating for thrips and mites, spray foliage, buds, and the soil around the plant. Thrips are a tiny winged insect with a slender body. Distortion such as curling and gnarling leaves indicate the presence of leafhoppers, stinkbugs, and aphids in the garden. These insects suck sap from plants, and this causes the leaves to distort and drop off. These bugs can be treated by spraying the plants with water, but use insecticide for more severe infestations. Fungi and other similar organisms can infest plants as well. In particular, blackspot mold, powdery mildew, and downy mildew can cause fuzzy or powdery spots on leaves. These problems are not caused by insects, so they can't be controlled with insecticide. The best way to control these issues is to prevent them by watering plants from below so the leaves don't get wet. Remove any leaves that show signs of infection.

What is a summary?
Look for holes in the leaves. Check for discolored leaves. Inspect leaves for distortion. Look for fuzzy black, white, and yellow spots.
