Do Ants Eat Plants

However, the presence of ants in your garden can indicate something else. To know everything about ants in your garden as well as how to remove them and keep your plants safe, read this article.

Do Ants Eat Plants?

Yes, ants do sometimes eat plants. They are insects that usually eat other insects or look for dead materials (both plant and animal) to eat – depending on the species. However, some species of ant such as the leaf cutter ants do eat plants. 

These ants do just what the name says! They cut the leaves of the plants and feed some to fungi that they cultivate in their colony and they can spell disaster for your garden. Thankfully, they can only be found in South America, Central America, South Texas, and a few other places.

As for most of the ants that you are likely to see in your garden, they are entering the garden for other reasons. One major reason why they enter your garden is to harvest the sap of mealybugs, aphids, and other sap-sucking insects.

These parasites excrete a substance called honeydew which the ants drink. Ants also enter your garden when they see other insects and little animals that they can carry to their colony.

Ants may also just be passing through your garden and mean no harm. One great thing about ants is that they are very easy to locate. You can easily tell where they are going to and where they are coming from. You only need to be attentive and follow their movement.

What Attracts Ants to Your Garden Plants?

Some things that attract ants to your garden plants are dying plants, sap-sucking insects, food waste and other ant foods, fungi and bacteria, and decomposing plants. More innocently, though, the ants may just be passing through your garden as well. 

– Sap-Sucking Insects

Did you know that ants are in a symbiotic relationship with mealybugs, aphids, and other insects? The type of relationship in ecology is referred to as “Mutualism” and it refers to a relationship where both parties gain from each other.

Even though ants may not be eating your plants, they will protect aphids and other sap-sucking insects that are eating your plants and harvest their honeydew.

This means that the presence of ants in your garden can tell you that there are aphids, mealybugs, and other sap-sucking insects in your garden. If you observe the ants carefully, you can tell where the insects are.

– Dying Plants

Ants are scavengers. This means that they are always on the watch for organic materials that they can carry to their colony. Thankfully, most of them choose to avoid living plants. However, they will collect dying plants, fruits, and other materials from your garden to the colony.

In this case, the ants are beneficial to you because they keep your garden clean and safe. They also tell you which plant is dying in the garden. It is now up to you to find the cause of the dying plants. Please note that ants carrying dead leaves from your garden are not responsible for the death of the plants.

– Food Waste and Other Ant Foods

Did you mistakenly spill sugar on the ground? When last did you clean your garden and remove all the food waste? Remember that food attracts ants, so if you do not want ants in your garden, you need to remove what attracts them. Keep your garden clean. Well, the presence of ants in the garden will be beneficial to you, as they will help you to keep the garden clean.

– Fungi and Bacteria

Ants can get rid of harmful microbes in your garden. When organic materials in your garden are decomposing, they attract a lot of fungi and bacteria. By taking these materials away from your garden, ants can keep your plants and the garden generally safe from harmful microbes. 

Well, note that not all microbes are harmful, as there are beneficial ones. Some species of ants also eat microbes, so they help to control the microbe population in your garden.

– They Are Just Passing Through the Garden

The ants may just be moving from one point to another without disturbing your plants. For example, if your garden is between the ant colony and their food source, they will pass through your garden. You can tell that the ants mean no harm when they do not stay on your garden plants for long.

When ants are passing through your garden, they will not climb the plants except they really need to. This means that a majority of the walking ants will walk on the soil. You can observe how they walk and where they are headed to know if they are just passing through your garden or not.

How Do You Keep Ants Away From Your Plants?

To keep ants away from your plants, you need to remove all the aphids, mealybugs, and other sap-sucking insects in the garden.
