Garden Phlox Bugs: Common Pests and How to Control Them

Garden phlox is a beautiful flowering plant that can add color and vibrancy to any garden. However, like all plants, it is susceptible to pests and diseases that can damage or even kill it. In this article, we will discuss some of the most common garden phlox bugs and how you can control them to keep your plants healthy and thriving.

1. Japanese Beetles

Japanese beetles are one of the most common pests that attack garden phlox. They are metallic green with copper-brown wings and can be easily identified by their size and distinctive coloring. Japanese beetles feed on the leaves of garden phlox, causing them to turn brown and fall off. They can also cause significant damage to other plants in your garden.

To control Japanese beetles, you can use pheromone traps or insecticides. Pheromone traps are designed to attract and trap adult beetles before they can lay eggs or cause damage to your plants. Insecticides can be used to kill both adult beetles and their larvae, but should be used sparingly and only as a last resort.

2. Spider Mites

Spider mites are tiny pests that are difficult to see with the naked eye. They are typically found on the underside of garden phlox leaves and feed by sucking sap from the plant. This can cause leaves to turn yellow and eventually fall off. Spider mites can also create webbing on your plants, which can be unsightly.

To control spider mites, you can use an insecticidal soap or neem oil spray. These products can be sprayed directly onto affected leaves to kill spider mites and their eggs. You can also increase humidity around your plants by misting them with water, which can help deter spider mite infestations.

3. Aphids

Aphids are tiny, soft-bodied insects that come in many colors, including green, yellow, and black. They feed on the sap of garden phlox leaves and can cause stunted growth, yellowing leaves, and distorted flowers. Aphids can also attract ants to your plants and create a sticky residue called honeydew.

To control aphids, you can spray your plants with a mixture of water and dish soap. This will suffocate the aphids and wash away their honeydew. You can also introduce natural predators like ladybugs and lacewings to your garden, which will eat aphids and keep their populations under control.

4. Thrips

Thrips are tiny, slender insects that are difficult to see without a magnifying glass. They feed on the sap of garden phlox leaves and can cause them to turn yellow or brown. Thrips can also cause distorted growth and leave behind silver streaks on your plants.

To control thrips, you can use sticky traps or insecticides. Sticky traps are designed to catch and kill adult thrips before they can reproduce. Insecticides can be used to kill both adult thrips and their larvae, but should be used sparingly and only as a last resort.

5. Slugs and Snails

Slugs and snails are common garden pests that can cause significant damage to your plants. They feed on the foliage of garden phlox, leaving large holes and irregular edges. They are most active at night and can be difficult to spot during the day.

To control slugs and snails, you can use bait traps or handpick them from your plants. Bait traps are designed to attract slugs and snails and then drown them in a liquid solution. Handpicking involves physically removing slugs and snails from your plants and disposing of them in a bucket of soapy water.
