What Insects Are Bad for Your Trees?

December 8, 2021

Anyone with trees knows that pests can be a major problem—but identifying which bugs will kill your trees can sometimes be difficult, especially if you’re new to an area. You don’t want to accidentally get rid of beneficial insects. That’s why we’ve covered some of the worst insects for trees.

Read on for information on what insects are bad for your trees:

  • Aphids: Aphids are pests known for destroying plants. These insects don’t usually cause much trouble for trees, but a large population of them could destroy leaves. In large numbers, aphids can turn leaves yellow and stunt shoots. You can use pesticides to get rid of the aphids in your yard; however, if you’re looking for a more natural method, consider introducing ladybugs, which are natural predators of aphids. You can do so by planting certain plants, including cilantro, dill and fennel.
  • Whiteflies: These small, winged insects can suck nutrients from your tree’s leaves, causing them to wilt and fall off. Once on the ground, leaves will eventually rot, allowing for the growth of mold and other types of fungus. Whiteflies are quite common, though they usually prefer vegetable plants. The best way to get rid of whiteflies is by spraying your plants with a mixture of 1 tablespoon of dish soap and 1 gallon of water.
  • Termites: When searching for which bugs will kill your trees, you’ve likely come across termites. While termites do enjoy burrowing through wood, most species prefer dead wood, so if you see termites, chances are it’s time to have that tree removed. That said, there are some termite species that burrow through live wood as well. Formosan termites, for example, can cause major damage to cypress, ash and many other tree species.
  • Emerald ash borers: While they’ve not made their way to California yet, some believe California olive trees could soon be at risk for emerald ash borer infestations. These metallic-green beetles lay their eggs on ash trees. Once the larvae emerge, they bore into the tree and start consuming its nutrients. This often results in dieback and bark- In Michigan alone, this insect has destroyed over 40 million trees. If you notice one in your yard, be sure to contact a professional right away.
  • Other problem insects: It’s hard to cover all the bugs that may kill your trees, but some others to look out for include mites, psyllids and adelgids. There are natural ways to remove many of these pests, though many people prefer to call in an exterminator first.

So what insects are bad for your trees? As you can see, there are a lot of them, but providing your tree with proper maintenance will help prevent insect infestations and other problems. If you don’t have the time or energy to provide your tree with regular maintenance, be sure to contact a professional arborist in your area.
