You just walked outside, looked up, and freaked out because it looked like your tree leaves had caught fire.

The edges are black, almost rotted-looking. Or it looks like someone took an axe to your tree trunk.

If that’s what you see, you have a bug problem.

Here’s how you can kill the bugs on your tree (without having to chop it down):

5 Organic Ways To Get Rid of Tree Bugs

We’re all about organic solutions (just look at our name). 

So while— yes — a simple tree bug spray from Home Depot might (keyword…might) do the trick, don’t you want to make sure all those chemicals aren’t preventing your kids or pets from playing in the yard?

So before you start spraying pesticides on your tree like it’s the Wild West, try these equally-as-good-and-actually-kinda-better ways to get rid of tree bugs:

  1. Beneficial Insects: Introduce natural predators like ladybugs or lacewings to your garden. These helpful bugs feast on the pests that are bothering your trees.
  2. Neem Oil: Neem oil is a natural insecticide that disrupts the life cycle of many tree-damaging bugs. Mix it with water and spray it on your trees to keep the pests at bay.
  3. Diatomaceous Earth: This powdery substance might sound fancy, but it’s actually just ground-up fossilized algae. Sprinkle it around the base of your trees to create a barrier that bugs won’t want to cross.
  4. Essential Oils: Certain essential oils like peppermint or tea tree oil can repel insects effectively. Mix a few drops with water in a spray bottle and apply it to your trees.
  5. Garlic Spray: Bugs might not enjoy the smell of garlic as much as we do. Blend up some garlic cloves with water, strain the mixture, and spray it onto your trees to deter pests.

These might sound a little woo-woo, but they work. We’ve tried them ourselves.

How The Pros Do It

However, if your tree looks like it’s one Thanos snap from disintegrating from existence, here’s what we would do to kill the bugs on your tree:

  1. Systemic Insecticides: These are chemicals applied to the soil or directly injected into trees. They are absorbed by the roots or trunk and transported throughout the tree’s tissues, providing long-term protection against pests.
  2. Biological Control Agents: In other words: introduce natural enemies kill your tree bugs for you. Some well-know tree bug nemisis’ are ladybugs and nematodes.
  3. Trunk Injection: Trunk injection involves injecting insecticides directly into the trunk of infested trees, distributed throughout the tree’s vascular system. This method delivers targeted treatment while minimizing pesticide exposure to non-target organisms and reducing environmental contamination.
  4. Integrated Pest Management (IPM): This means we use combination of methods to get to a very specific situation. For example, we’ll likely combine monitoring, targeted spraying, and pruning to bring your tree back to life. 
  5. Tree Removal: In cases where pest infestations have caused irreparable damage or pose a significant risk to surrounding trees or structures, professional pest control experts may recommend tree removal. This involves safely cutting down and disposing of infested trees to prevent the spread of pests to nearby vegetation. 

What Bugs Destroy Trees?

First things first: let’s address the big question. 

What bugs are causing all the trouble for our leafy friends? 

Well, there’s quite a variety out there, from beetles to aphids to caterpillars. These tiny critters can munch away at leaves, bore into bark, and ultimately weaken or even kill trees if left unchecked.

Here are 5 to look out for specifically for our fellow Florida friends:

Let’s focus on these bugs commonly found in Florida trees:

1. Sri Lanka Weevil

Sri Lanka weevils are small beetles with elongated bodies measuring about 1/4 inch in length. They are distinctively reddish-brown with yellow spots on their wing covers.

  • Host Trees: Sri Lanka weevils infest various plants, including ornamentals such as hibiscus, palms, and cycads.
  • Control: Apply insecticidal sprays containing pyrethroids or neonicotinoids to target adult weevils. Use systemic insecticides to protect plants from larval feeding.

2. Aphids

Aphids are small, soft-bodied insects ranging from green to black in color. They have pear-shaped bodies and long antennae.

3. Termites

Termites are small, pale insects with soft bodies and straight antennae. They live in colonies and feed on cellulose material, including wood.

  • Host Trees: Termites can infest any tree with wood components, including live trees, deadwood, and wooden structures.
  • Control: Implement preventive measures such as removing deadwood and maintaining proper drainage around trees. Use termite baits or apply liquid termiticides around the base of infested trees.

4. Chinch Bugs

Chinch bugs are small, black insects with white wings and distinctive red markings on their bodies.

  • Host Trees: Chinch bugs primarily infest St. Augustine grass but can feed on ornamental and turf grasses.
  • Control: Use insecticidal sprays containing pyrethroids or carbamates to target chinch bugs. Maintain proper lawn care practices to promote grass health and resilience.

5. Bark Beetles

Bark beetles are small, cylindrical insects with hard exoskeletons. They vary in color but often have dark brown or black bodies.

    • Host Trees: Bark beetles infest on pine, spruce, and fir trees.
    • Control: Utilize preventive measures such as maintaining tree vigor and removing stressed or weakened trees. Insecticide treatments may be applied to protect high-value trees from infestation.

How To Protect Trees from Insects

Once you get rid of your tree bugs, you’ll probably think,

“Alright, let’s not let that happen again.”

Here’s exactly what you’re going to do to make sure your trees don’t get inviltrated by by bugs:

  • Regular Inspections: Look for any signs of bug infestation, such as chewed leaves or unusual spots on the bark.
  • Pruning: Removing dead or diseased branches can improve your trees’ overall health and make them less attractive to pests.
  • Mulching: A layer of mulch around the base of your trees not only helps retain moisture but can also discourage pests from laying eggs in the soil.
  • Healthy Soil: Maintain good soil health by fertilizing and aerating regularly. Healthy trees are better equipped to fend off insect attacks.
  • Watering: Avoid overwatering, as it can attract certain pests, but make sure your trees get enough moisture to stay strong.
