Garden Phlox Bugs: How to Identify and Control Them
Garden phlox is a beautiful and popular flowering perennial that can add color and variety to any garden. However, this plant is prone to a variety of insect pests that can cause damage and make it less healthy and attractive. In this article, we will take a look at some of the most common bugs that affect garden phlox and share tips on how to identify and control them.
1. Aphids
Aphids are small, soft-bodied insects that come in many colors, including green, yellow, brown, and black. They are often found on the undersides of leaves or on the new growth of plants. Aphids feed by sucking sap from the plant, which can cause leaves to wilt and curl. They can also secrete a sticky substance called honeydew, which can attract ants and other insects.
To control aphids on garden phlox, you can try spraying them with a strong jet of water from a hose. You can also use insecticidal soap or neem oil to kill aphids. Ladybugs and lacewings are natural predators of aphids and can help keep their populations in check.
2. Spider Mites
Spider mites are tiny, spider-like insects that are usually found on the undersides of leaves. They feed by piercing the plant cells and sucking out their contents, which can cause leaves to turn yellow and dry up. Spider mites are most active in hot, dry weather and can reproduce quickly, leading to large infestations.
To control spider mites on garden phlox, you can spray them with a mixture of water, dish soap, and rubbing alcohol. You can also use insecticidal soap or neem oil. Be sure to water your plants regularly and provide them with plenty of shade to prevent spider mites from becoming a problem.
3. Thrips
Thrips are tiny, slender insects that can be difficult to see without magnification. They feed by scraping and rasping the surface of leaves and flowers, which can cause them to become distorted and discolored. Thrips can also spread plant diseases, making them a serious threat to garden phlox and other plants.
To control thrips on garden phlox, you can try spraying them with insecticidal soap or neem oil. You can also remove affected leaves and flowers and dispose of them to prevent thrips from spreading. Introducing beneficial insects like predatory mites and minute pirate bugs can also help control thrip populations naturally.
4. Japanese Beetles
Japanese beetles are a familiar pest to many gardeners. These shiny, metallic-looking beetles are about half an inch long and feed on the leaves and flowers of many different plants, including garden phlox. Their feeding can cause leaves to become skeletonized, leaving only the veins intact.
To control Japanese beetles on garden phlox, you can try picking them off by hand and dropping them into a bucket of soapy water. You can also use a systemic insecticide containing imidacloprid, which is taken up by the plant and kills beetles when they feed on it.
5. Leafhoppers
Leafhoppers are small, wedge-shaped insects that can move quickly by jumping or flying. They feed by sucking sap from the leaves of plants, which can cause them to turn yellow and become stunted. Leafhoppers can also spread plant diseases, making them a serious threat to garden phlox and other plants.
To control leafhoppers on garden phlox, you can try spraying them with insecticidal soap or neem oil. You can also introduce beneficial insects like ladybugs and lacewings, which are natural predators of leafhoppers. Keeping your garden clean and free of debris can also help reduce leafhopper populations.

Garden phlox can be a beautiful addition to any garden, but it is important to be aware of the various insect pests that can affect it. By learning to identify these pests and taking steps to control them, you can keep your garden phlox healthy and vibrant all season long.
