If you’ve been noticing green bugs on your trees, you’re likely wondering what they are and how they impact your plants. Aphids are a common type of green bug that can cause significant damage to leaves and plants if left untreated. In this blog post, we will discuss everything you need to know about aphids: what they look like, where they thrive, how to get rid of them, and more!

What Are Aphids?

Aphids are small, soft-bodied, pear-shaped insects that range in color from green to brown to black, though green is by far the most common. They have long antennae and legs, and they reproduce quickly – a single aphid can produce up to 80 offspring in just one week! Aphids feed on the sap of plants, which can cause leaves to yellow and wilt. Similarly to soft scales, they also produce a sticky substance called honeydew, which can attract other pests and promote the growth of sooty mold.

Where Do Aphids Thrive?

Aphids prefer to feed on young, tender leaves. Aphids are also most commonly found on the undersides of leaves, where they can go undetected. However, they can be found on any part of the plant, including the stems, flowers, and roots. Aphids are most active in spring and summer, but they can survive year-round in warm climates.

An aphid’s favorite trees are:

Common Aphid Damage on Leaves

One of the most common signs of aphid damage is curled, distorted, or yellowing leaves. Aphids can also cause stunted plant growth, and they may transmit diseases from one plant to another.

How to get rid of aphids

If you suspect that your plants have aphids, it’s important to take action quickly to prevent further damage. There are a few different ways to get rid of aphids, including:

Water Hosing

Hosing them off with water: This is the simplest and most effective method for getting rid of aphids. Just aim for a strong stream of water at the affected plants, and the aphids will be knocked off.

Insecticidal Soap

Spraying them with insecticidal soap: You can make your own insecticidal soap by mixing one part dish soap with four parts water. Just be sure to test the solution on a small area of the plant first, as some plants are sensitive to soap.

Introduce Aphid Predators

Introducing beneficial insects: Ladybugs and lacewings are two common predators of aphids. You can purchase these insects from a garden center or online and release them into your garden.

Repel with Neem Oil

Applying neem oil: Neem oil is a natural substance that repels aphids and other pests. Just be sure to follow the instructions on the label very carefully, as neem oil can be harmful to plants if used incorrectly. If at all in doubt, go the safe route and have a professional handle applying it for you!

Preventing Aphids in the Future

The best way to prevent aphids is to keep your plants healthy and strong. This means watering them regularly, fertilizing them as needed, and pruning away dead or dying leaves. You should also inspect your plants regularly for signs of pests and take action immediately if you see anything suspicious. Aphids can cause serious damage to your plants if left unchecked. However, with a little effort in following these simple tips, you can get rid of them and keep your garden healthy, happy, and aphid-free!
