Insecticides for Trees: What Are the Options?

The spring season is rightly known as the new beginning. Plants grow new leaves, flowers, and fruits. But the warmer season also brings along insects. So, you should know about the suitable insecticides for trees in your yard.

Insects can drain the nutrients and eat away your trees. So, it’s important to apply appropriate insecticide to retain tree health.

First, let’s take a look at some common harmful insects:

  • Bark beetles
  • Moths
  • Caterpillars
  • Budworms
  • Grasshoppers
  • Leaf miner
  • Mites
  • Bagworms
  • Boring insects


Determine the Types of Insects

Do you know what kinds of insects have invaded your yard trees? You should first determine their type. After all, not all insects are bad!

You can then choose a suitable insecticide to kill off harmful insects. This information will guide you about the amount of insecticide you should apply. Also, you can decide about the method of application for desired results.

It’s not always easy to see small insects with a naked eye. So, pay attention to tree health. Leaf and stem changes can provide lots of useful information.

It’s also a good idea to learn more about trees in your yard. This way, you can find out which insects are likely to harm your precious garden.


Types of Insecticides for Trees

Insecticides fall into three categories: Stomach poisons, contact poisons, and fumigants.

But the use of fumigants isn’t common in residential landscapes.

Stomach poisons tend to target chewing insects. You can spray it on the leaves and stems of infected trees. But always remember these chemicals are harmful to humans and pets. So, you can instead use synthetic insecticides since they are less dangerous.

Piercing-sucking pests feed below the plant surface. This includes aphids, mites, and leafhoppers. So, it’s easy for them to avoid contact with stomach poisons.

Contact-residual insecticides kill a wider range of pests. They remain effective for 1 to 4 weeks. On the other hand, systemic insecticides give 6 or more weeks of protection.


Apply the Insecticide

Now that you know about insecticides, you can make the right choice. Contact insecticides work well for immediate control. And systemic insecticides are useful for long-term control. But the latter option isn’t suitable for edible plants.

You can prepare an organic insecticide at home or buy an insecticide product. Pay close attention to manufacturer instructions.
