Are Ants Harmful to Trees?

Trees and pests don’t work well together. But is it really that easy? It’s not always clear-cut when it comes to ants around our trees and their roots and stems. There are kinds of ants that don’t hurt trees and can even help them stay healthy. Others, however, may be harmful to trees. Find out how to get rid of harmful tree ants from our Gainesville arborists’ tips below. If you have ants near or on your trees that are hurting them or making them look bad, read on.

If you’ve noticed ants crawling on your trees or swarming around the base, you may be wondering – are these insects actually hurting my trees? The answer is complicated, but in most cases ants are not directly damaging to tree health. However, their presence can sometimes indicate other issues that do require attention. Read on to learn more about ants on trees and when intervention may be needed.

Why Are Ants Attracted to Trees?

Ants are commonly found on and around trees for a couple key reasons:

  • Sugary sap – Many ants feed on the naturally occurring sap and honeydew produced by trees and other insects living in the tree. This sweet treat draws ants to colonize.

  • Shelter – Rot holes crevices and other cavities in aging or damaged trees provide ideal nesting sites and protection for ants.

So generally, ants are not harming the tree itself, but rather taking advantage of resources the tree provides.

Do Ants Damage Trees?

In most cases, ants living in or on a tree do not cause direct damage to the tree’s health. In fact, eliminating ants could do more harm than good by disrupting the intricate ecosystem and pest control that ants can provide.

However there are a couple scenarios where ants indicate a potential tree threat

  • Carpenter ants – These large black ants burrow into and nest within decaying wood Their presence may signal rot or structural issues

  • Fire ants – The venomous sting and mound-building of these ants can damage young trees and tree roots.

Outside of these exceptions, ants are generally harmless or even beneficial as predators of tree-damaging insects.

Signs Ants Are Farming Pests

Some types of ants have a mutualistic relationship with sap-sucking insects like aphids, protecting them from predators in exchange for feeding on their sugary honeydew secretions. If you notice:

  • Ant trails leading to sticky or sooty mold growth
  • Clusters of aphids or other soft-bodied insects on the tree
  • Ants aggressively defending these insect colonies

Then the ants may be “farming” pests which can cause extensive damage to the tree. Treatment in this case focuses on controlling the sap feeders, not just eliminating ants.

When to Take Action Against Ants

Here are some signs it may be prudent to intervene against ants on your trees:

  • Large ant mounds or colonies accumulating around roots and the tree base
  • Evidence of carpenter ant nesting within damaged wood
  • Ants aggressively swarming or stinging people or pets near the tree
  • Ants clearly tending colonies of damaging sap-sucking insects

Non-toxic methods like pruning away dead wood, applying sticky barriers, or introducing natural predators can help control harmful ants. But bringing in an arborist is highly recommended before using any pesticides on your trees.

Ant Prevention Tips

While ants on trees are usually harmless, you can discourage them from colonizing with proper tree care:

  • Prune away dead wood where carpenter ants would nest
  • Monitor for and control sap-sucking insects like aphids or scales
  • Clear leaf litter and debris from around the tree base
  • Apply sticky barriers around the trunk if ants are a nuisance
  • Maintain healthy soil and avoid over-mulching, as ants nest in dry, dead material

With a little diligent tree care, ants don’t have to become a nuisance. Focus on maintaining tree vigor and promptly addressing any signs of decay or pest infestations. A thriving tree ecosystem will keep ant populations in balance.

What Kind Of Ants Live In Trees?

Ants are drawn to trees and their surroundings for food and shelter. Ants get into trees to feed on the sweet sap and honeydew that other bugs leave behind. They also look for shelter in trees with holes, rotting wood, and other openings. Two varieties of ants can be a problem for your trees. However, it’s important to note that not all ants of these varieties will pose a problem for trees. Looking for professional tree restoration and preservation services? Contact SkyFrog Tree Service.

Red Imported Fire Ants

Red imported fire ants, which are also just called “fire ants,” can be very bad for young trees, pets, and people. People or animals like dogs and cats can get stung by the ants, which will leave behind painful blisters. If you spot dome-shaped mounds at the base of your trees, those are likely ant hills. Be sure to avoid touching or disturbing them. These small, dark-red ants will sting whatever disturbs their mounds. Talk to an arborist in your area about how to get rid of these stinging ants from your trees in the safest way.

Carpenter ants construct mounds of sawdust at the base of trees. There may be black ants in the area where you see piles of sawdust at the base of a tree. In this case, you should talk to an arborist to find out if the tree needs to be cut down or if it can be fixed. Because these ants can only burrow in dead or rotting tree wood, trees that are infested with them can become so badly damaged that they could be dangerous.

Are Ants in a Tree Bad?


Do trees benefit from ants?

The trees typically benefit from having their ant guests, as the ants defend the trees from large herbivores. Pringle said the ants serve as a “standing army” that bites any would-be plant-eaters until they give up and move on to another tree.

Are ants good for trees?

First off, ants offer several benefits to your trees. For starters, they loosen the soil and help you aerate the soil. The nests and tunnels create pores in the soil, which creates pores, thus allowing nutrients and water to travel in the soil properly. In a way, they improve the quality of the soil, thus helping your trees grow.
