What Are the Signs of Insect Infestation in Trees?
Trees are an essential part of any home or business’s landscaping. All trees can experience an infestation and spotting it early can help prevent it from spreading and becoming a bigger issue. A pest infestation can weaken a tree’s structure and lead to its death if untreated. Protecting your tree from insect issues is easy when you can identify warning signs early on. Below are some of the most common indicators of a pest issue and what to watch for when inspecting your trees.
Visible Insects On The Tree
One of the most obvious signs of an infestation is seeing the pests themselves on the tree. Seeing a single insect on your tree may not be a sign of an infestation. Many insects are harmless or even beneficial to trees, but there are a handful of insects that are known to be destructive. It is important to identify them as early as possible to keep your tree healthy. If you see the same insect repeatedly over several days, in different parts of the tree, or find clusters and groups of them, you may have discovered an infestation issue. It is also common to find eggs or larvae on branches or under leaves, which means more are on the way. Damage to your tree’s leaves is a big sign of an issue. Keep an eye out for any chewed edges, holes, or sticky residues on the surface of your leaves. If you are experiencing any of the above, take a photo and call Joseph Tree today. We will help you determine if the insects you are noticing are harmful and help you stop the issue from getting bigger if there is an active infestation.
Holes In Your Tree’s Branches Or Trunk
Finding holes in your tree’s branches or trunk is often a sign of borer insect activity. Wood boring insects will make tunnels into your tree and lay eggs. This will weaken your tree’s structure over time. When observing your tree for pests, keep a lookout for small, round, or oval holes. These holes are usually accompanied by a sawdust-like material around or near the opening. Early detection of boring insects is crucial to your tree’s survival. These types of insects can do a significant amount of harm in a short amount of time. It won’t be long until your tree starts showing outward signs of stress if you do not treat it quickly.
Excessive Leaf Loss Or Damage
One of the earliest signs of stress or damage your tree will show if there is an insect infestation is excessive leaf loss or visible damage. It is normal for certain types of trees to shed leaves seasonally, but sudden or heavy drops during the growing season is a major issue. Yellowing or chewed leaves are big indicators that you may have caterpillars, aphids, or beetles feeding on your tree’s leaves. If you find galls or bumps on some leaves, this could be a sign of wasps, mites, or fungi. Some insects will inject chemicals into the leaf tissue, and a swollen lump will appear. If you do not do anything to help your tree, it will continue to drop leaves and it will lose its ability to photosynthesize. This makes it more vulnerable to disease, and the stress it will experience can lead it to its death. Keeping an eye on the leaves of your tree throughout all seasons will help you catch insect issues before they escalate.
Sudden Appearance Of A Sticky Residue
If you are having any issues with sap-sucking insects, you may notice a sticky or shiny residue on your tree’s leaves or branches. Some pests will secrete a substance called honeydew when they are actively feeding on a tree’s sap. Honeydew can lead to the growth of sooty mold, and it can also attract ants. This sticky residue isn’t always a huge concern, but it is important to watch that it doesn’t become a bigger issue. If you start seeing an influx of ants or a black powdery fungus coating your leaves, it is time to call your arborist and get this issue treated.
Cracked Or Peeling Bark
When checking on the health of your tree, keep an eye on the bark at the trunk and branches. Cracks, sunken areas, holes, discoloration, or peeling are a clear sign of an infestation. The bark is the protective barrier for the tree, and its health is essential to keeping your tree alive. If the bark is brittle to the touch and insects are weakening this protective barrier, your tree is more susceptible to disease and dehydration.
Unusual Animal Activity
Unusual animal activity around a tree can be a sign of an infestation. Ants, wasps, hornets, or deer can indicate the presence of sap-sucking pests. Woodpeckers will repeatedly peck at bark to find hidden insect larvae. Raccoons and opossums will be able to easily dig into rotting and insect-infested wood to find bugs to eat. If you notice an influx of animal activity, especially if it is focused on one tree, it is a good idea to inspect it closely or consult a professional to see if there are any bigger issues.
