Ants Like Mango Trees – What To Do & When To Be Concerned

One may often come across ants on mango trees for two main reasons.

  1. They’re attracted to a food source, like aphids or scale
  2. They are nesting within the bark of the tree.

Some ants indicate a problem with your tree, but other types of ants (like weaver ants) are actually actively working to protect your tree.

Key Takeaways

  • Different ant species have varied impacts on mango trees, with some being beneficial and others potentially harmful.
  • Weaver ants play a crucial role as natural pest controllers, warding off harmful insects from the tree.
  • Effective strategies can be implemented to manage or remove ant populations without harming the tree.
  • A holistic approach, considering the broader ecosystem, is vital for the health and productivity of mango trees.

Identify Types of Ants Found on Mango Trees

Ants, with their tiny bodies and incredible strength, have long been a subject of fascination.

Around a mango tree, you might encounter a multitude of these insects, making it their living space, feeding ground, or even a pathway to something more.

While some ants play the role of protectors, ensuring no harmful pests approach the tree, others might indicate an underlying issue, such as the presence of pests.

Here, we break down the common ants you might notice on your mango tree.

Weaver Ants

Weaver ants are a common sight in many tropical orchards. These ants exhibit a remarkable behavior: they use silk produced by their larvae to “weave” or join leaves together to form their nests.

This nest-building activity at the edge of leaves can sometimes cause the leaves to fold or curl up. However, they’re not just notable for their construction skills.

Weaver ants are also aggressive predators, protecting the mango tree from potential pests like aphids or scale insects.

They even create an alarm pheromone that alerts the entire colony when a threat is nearby. Thanks to these guys, many pests would think twice before setting foot on a tree guarded by weaver ants.

Sugar Ants

Sugar ants, often identified by their small black appearance, have a penchant for all things sweet.

If there’s a crack in the fruit skin or oozing sap from the tree, these ants will be one of the first to find it.

Their presence might indicate that your mango tree has ripe or overripe fruits, which they are keen to feed on.

Additionally, they might also lead you to areas where the tree’s sap is seeping out, pointing toward potential injuries or areas that might need attention.

Carpenter Ants

As their name suggests, carpenter ants have a knack for woodworking.

However, unlike their beneficial counterparts, the carpenter bees that pollinate, these ants can pose a threat to your mango tree.

They carve out tunnels within the wood to establish their nests, which can compromise the structural integrity of the tree over the span of several years.

Regularly inspecting the tree for small, round holes or sawdust-like frass can help identify their presence.

It’s crucial to take action at the first sign to ensure they don’t cause irreparable damage.

Acrobat Ants

Acrobat ants are quite the little gymnasts. With their heart-shaped abdomen, they can bend it over their body when disturbed, a trait that gives them their name.

These ants are particularly fond of honeydew, a sticky substance produced by pests like aphids.

Their presence might indicate an infestation of these pests, which the ants “farm” and protect to ensure a constant honeydew supply.

If you notice them on your mango tree, it’s a good signal that it’s time to inspect for other pests.

Fire Ants

The fiery red color and painful sting make fire ants hard to miss.

Although they’re more ground-dwelling, if you find them around the tree, especially near its base, it could indicate they’re searching for food or even establishing a new nest nearby.

Their stings can be harmful, so care should be taken. They aren’t directly harmful to the tree but can attack young sprouts or small mango fruits lying on the ground.

Ghost Ants

Another species to look out for is the ghost ant, named for its pale, almost translucent appearance.

These ants are highly adaptable and are usually found in warm, humid areas, which makes a mango orchard a suitable home. They feed on both plant and animal matter.

Although they aren’t as harmful as some other pests, their presence can indicate that the tree might be providing them with some source of food, such as honeydew from aphids or scale insects.

Leafcutter Ants

Leafcutter ants get their name from their unique behavior of cutting out small portions of green leaves and carrying them back to their nests.

However, contrary to what one might think, they don’t eat the leaves.

Instead, they use them to cultivate a special type of fungus in their underground nest that serves as their primary food source.

When you notice neat, circular cut-outs on the leaves of your mango tree, it’s a good indicator that leafcutter ants are at work.

While a few missing leaf portions might not harm a mature mango tree, a large colony can defoliate a significant portion of the tree, affecting its overall health and reducing its ability to photosynthesize efficiently.

Young trees or saplings can be particularly vulnerable. The extensive network of underground tunnels that the ants create can also impact the roots of plants and the overall soil structure.

What Ants on Mango Trees Indicate

When you see ants actively moving up and down a mango tree, it’s usually a sign that there’s something of interest to them on the tree.

In nature, everything is interconnected, and the presence of ants on your tree could be pointing toward various situations.

1. Honeydew Producers

Ants, especially species like the acrobat ants, have a fondness for honeydew, a sugary substance produced by pests like aphids and scale insects.

When ants are attracted to a tree in large numbers, it might indicate the presence of these pests.

2. Food Source

Trees sometimes secrete sap, and fruits might exude juices, especially when they’re ripe or overripe.

Sugar ants, given their love for sweet substances, might indicate that your mangoes are ready for harvest or there’s an injury to the tree that’s releasing sap.

3. Shelter

Some ants, like carpenter ants, seek trees for nesting purposes. Their presence in large numbers or evidence of their woodworking on the tree is a sign that they’re setting up their colony within the tree.

Potential Benefits of Ants on Mango Tree

Ants might seem like tiny, inconsequential insects, but their role in the ecosystem of a mango tree can be significant:

Many ants are predators of common pests. Weaver ants, for instance, are known to keep populations of harmful insects in check, reducing the need for chemical pesticides.

While ants aren’t the primary pollinators of mango trees, their movement across the tree can sometimes aid in the pollination process, ensuring good fruit yield.

Ants that nest in the ground, like fire ants, often help in aerating the soil. Their tunneling activities can facilitate better water penetration and root growth for the tree.

Ants play a role in breaking down organic matter, be it fallen mangoes or other plant debris. This decomposition enriches the soil, providing better nutrients for the tree.

Potential Damage Caused by Ants on Mango Tree

While ants can be beneficial, some can also cause harm:

Carpenter ants, as previously mentioned, burrow into the wood of the tree, which can compromise its structural integrity over the years.

Some ants farm aphids for their honeydew. In doing so, they protect these pests from their natural predators, leading to unchecked growth of the aphid population, which can harm the tree.

Some ants, like fire ants, can deliver painful stings. This can be a concern if the tree is in an area frequented by people, especially children.

Ants can sometimes outcompete or even prey on other beneficial insects, disrupting the natural balance and leading to increased pest issues.

Good News: Weaver Ants Are Nature’s Pest Controllers

Weaver ants are not just any ordinary ant species. Their unique behaviors and role in the ecosystem make them an incredible asset, especially for those cultivating mango trees.

While many might dismiss ants as pests, weaver ants highlight how these tiny creatures can play a pivotal role in safeguarding a mango tree.

Embracing their presence could lead to a healthier tree and, in turn, a bountiful mango harvest.

Natural Defense Against Pests

Weaver ants are voracious predators, constantly on the hunt for insects that might harm mango trees. These ants feed on a range of pests, including aphids, beetles, and caterpillars.

Their presence ensures that the tree is relatively free from these damaging pests, reducing the need for chemical interventions.

Incredible Nest Builders

Their name, “weaver ants,” stems from their unique nesting behavior. Worker ants work together, using their larvae’s silk to weave leaves into secure nests.

If you notice leaves on your mango tree bound together at the edge with silk, it’s a clear sign that a colony of weaver ants has made the tree their home.

This weaving activity rarely harms the tree and is a clear sign of the colony’s presence.

Territorial Behavior Benefits the Tree

Weaver ants are highly territorial creatures.

Once they’ve established their colony within a mango tree, they’ll fend off not only harmful pests but also other ant species that might farm aphids or scale insects.

This protective nature ensures that the mango tree remains in optimal health.

Potential Challenges

While weaver ants offer numerous benefits, they can sometimes be a bit aggressive, especially when their nest is disturbed.

Their bites, though not venomous, can be painful. It’s crucial to approach areas of the mango tree where they’ve built their nests with caution.

Integration in Organic Farming

Due to their impeccable pest-controlling abilities, many organic farmers have tried to introduce and maintain weaver ant colonies in their orchards.

This natural pest control strategy aligns well with organic farming principles, offering protection without the use of chemicals.

How To Get Rid of Ants on Mango Trees

Managing ants in an orchard, especially around your mango tree, is essential for balanced tree health. While certain ants play a beneficial role, others can be detrimental.

If you decide that it’s time to rid your tree of these little six-legged creatures, here are some steps and strategies:

Understanding the Ants: Before taking any measures, it’s crucial to identify which species of ants are residing in your tree.

Weaver ants, for instance, are beneficial, whereas carpenter ants can cause structural damage to the tree. Identification will guide the most appropriate and targeted removal strategy.

Diatomaceous Earth: This is a natural insect killer and can be sprinkled around the tree’s base. When ants walk over diatomaceous earth, it causes small cuts in their exoskeletons, leading to dehydration and death.

It’s an effective method, but ensure it remains dry as water can reduce its effectiveness.

Ant Baits: Ant baits like this one work by targeting the entire colony. Worker ants take the bait, which is typically a toxic substance mixed with something enticing like sugar, back to the nest, thereby poisoning the colony from within.

Natural Repellents: Some natural substances, such as lemon juice, peppermint oil, or cinnamon, can deter ants. Creating a barrier with these around the tree can prevent ants from climbing.

Tanglefoot Paste: This is a sticky substance that can be applied around the tree’s trunk, preventing ants from climbing up (find it here).

Before applying, ensure the tree’s trunk is wrapped with a protective layer, like fabric or paper, to prevent any direct contact and potential damage.

Keep the Area Clean: Ensuring there’s no food source around the tree will make it less attractive to ants.

Regularly remove fallen mangoes, clear away other plant debris, and manage aphids or scale insects, which might produce honeydew that ants feed on.

Introduce Natural Predators: Certain birds, like antbirds or woodpeckers, feed on ants. By creating a bird-friendly environment, you might attract these natural predators to help control the ant population.

Chemical Sprays: As a last resort, one could use pesticide sprays. However, it’s crucial to be cautious. These chemicals can harm beneficial insects and might leave residues on mango fruits.

If you choose to go this route, please read the label instructions carefully and consider the potential impacts on the broader ecosystem.
