If you’re a homeowner, you know that it’s essential to be vigilant when checking for signs of pests or diseases in your trees. A single tree pest can do a lot of damage, and before you know it, your whole tree could be infested. This article will discuss some of the most common warning signs of tree pests. Keep an eye out for these indications, and if you think your tree might be infected, call a professional immediately.
1. Discolored Leaves
If you notice that the leaves on your tree are turning yellow, brown, or black, this could be a sign of a pest infestation. Insects and other pests can damage your tree’s leaves, causing them to discolor. For example, caterpillars can eat away at your tree’s leaves, causing them to turn brown and brittle.
Wilting is another common sign of tree pests. Insects and other pests can suck the sap out of a tree, causing it to wilt and turning its leaves yellow and brown. Wilting can occur on a tree’s leaves and branches, so keep an eye out for any signs of it. For instance, the gypsy moth caterpillar is known for causing extensive tree damage, including wilting and yellowing of the leaves. The Asian long-horned beetle can also cause wilting in trees.
3. Holes or Notches in the Bark
Insects and other pests can damage the bark of a tree as well, leaving behind holes or notches that look as though they had been chewed by something. For example, the pine bark beetle can leave behind small holes in the bark of a tree, while the cottonwood borer can leave behind larger holes or notches. If you see any signs of damage to the bark of your tree, then it could be an indication of a pest infestation. The emerald ash borer, for instance, is known for causing extensive damage. It’s a beetle that feeds on ash trees.
Defoliation is one of the most common signs of tree pests. Pests can eat away at the leaves of a tree, causing it to lose its foliage. This can occur fairly rapidly, so it’s important to keep an eye out for any sign of this problem. Defoliation can also occur in waves, so if you see that your tree’s leaves are starting to disappear, it’s likely due to an infestation. The gypsy moth caterpillar mentioned earlier is known for causing massive defoliation in trees.
5. Sooty Mold
Sooty mold is a type of fungus that can grow on trees that are already infested with pests. This black, soot-like fungus can form on a tree’s leaves, stems, and branches. It is usually caused by insects that feed on the tree sap and excrete a sticky substance that allows for the growth of sooty mold. Among other things, an infestation of aphids often leads to the growth of this mold.
