The onset of Ants on plants is one of the most common situations both in gardens, orchards, and in indoor and outdoor pots. Although their natural presence can be beneficial to the balance of the ecosystem, When they proliferate excessively they can be harmful by facilitating the appearance of other pests and affecting the development of our plants.
Why do ants appear on our plants?
Ants are especially attracted to plants with pests such as aphids, mealybugs, and whiteflies due to the sugary honeydew these insects produce. They also seek out damp areas and soils rich in organic matter. In small quantities, ants aerate the soil and contribute to the decomposition of organic matter., but a colony that is too large can endanger the health of the plants and the garden.
The main problem lies in its ability to promote the growth of other pests like aphids, which they defend and protect by feeding on their secretions. They can also compete for soil nutrients and damage young roots or carry unwanted weed seeds.
Advantages and disadvantages of ants in the garden
Before applying any control method, it is necessary assess the role of ants in the environment:
- Benefits : They aerate the soil, help in pollination and accelerate the decomposition of organic matter.
- Disadvantages: They promote the appearance of pests, damage young roots and can cause defoliation. by transporting other insects or digging tunnels.
It is not always necessary to eliminate them completely., but it does control its population when it exceeds natural limits and compromises plant health.
Natural and sustainable remedies to eliminate ants from plants
Following you will find The best natural methods to keep away or eradicate ants in plants, pots, and gardensAll of them are ecological, economical, and environmentally friendly, perfect for those seeking to preserve biodiversity without resorting to chemical pesticides.
1. Garlic water: the great natural repellent
Garlic contains sulfur compounds that act as powerful insect repellentsYou can prepare garlic water by crushing several cloves and soaking them for 24-48 hours. Boil the solution for 20 minutes, strain, and spray around the affected areas, preferably at dawn or dusk to avoid burning the leaves.
2. Baking soda
Baking soda is safe for most plants. and acts as a drying agent and repellent. Sprinkle a continuous line around each affected plant. In addition to repelling ants, it helps keep the soil free of pathogens and fungi.
3. Lemon and vinegar
The acidity of the lemon and vinegar disorients ants by eliminating the pheromone trail they use to navigate. Mix equal parts vinegar or lemon juice and water, and spray or spread with cotton along the ants' paths. Test on a leaf before applying widely to avoid possible damage.
4. Cinnamon and cayenne pepper
These Aromatic powders are unpleasant for antsSprinkle cinnamon or a mixture of cinnamon and cayenne pepper along the paths and entrances to the anthill. Repeat this application for several days to keep colonies at bay. Cinnamon also has antifungal properties.
5. Infusion of wormwood, rue or mint
Wormwood, rue, and mint are strong-smelling plants with repellent properties. Prepare an infusion with fresh leaves and water, let it steep for several hours, and spray the solution in areas where you notice activity. You can also plant these species near the most affected plants.
6. Water and neutral soap
Dissolves a small amount of neutral or potassium soap in water and spray directly onto the ants and their trails. This removes the protective layer of their exoskeleton and hinders their mobility. It's important not to overdo it to avoid damaging the plant.
7. Orange peels and coffee grounds
Chop and scatter orange peels or sprinkle moist coffee grounds around your plants. Both products contain compounds that repel ants and also They contribute organic matter to the soil as they decompose.
8. Homemade traps with sugar and yeast
Mix yeast, water, and sugar to create an attractant that ants carry back to their nest. Fermentation produces gases that harm the colony. Apply only near the nest, away from edible plants.
9. Cork seedbed (carpet method)
Place a moist cork seed tray in the affected area. The ants will tend to move their nest here, making it easier to remove or relocate later. This method is especially useful when you don't want to apply substances to the soil.
Lesser-known methods and additional tips
- Sprinkle artificial sweetenerThe sweet taste attracts ants, but it's toxic to them. It's effective, but caution is advised if there are pets or children nearby.
- Borax with condensed milk: Mix borax and condensed milk or sugar to create a lethal bait, but it is also dangerous for animals and children.
- Cover the entrances to the anthill with Vaseline: A physical barrier that prevents the passage of ants without damaging the substrate or the plants.
- Purple cabbage or kale near the nest: They attract leaf-cutting ants, which feed and die from fermentation.
- Tying cotton with wire on trunks: The uncomfortable texture prevents them from climbing the trunk of plants and trees.
- Flood the anthill with boiling water: It is a drastic method and only recommended if the anthill is far from important roots, as it can damage nearby plants.
Natural repellent plants
One of the best ecological and preventive strategies is Plant aromatic plants with repellent effects near plants prone to ants.Among the most used are:
- Lavender
- Menta
- Thyme
- Rosemary
- Onion
- Wormwood
- Ruda
- Sesame
These plants also provide biodiversity and can attract beneficial pollinators while deterring ants.
Diatomaceous earth and neem oil: advanced ecological solutions
Diatomaceous earth is a natural mineral Composed of fossilized remains of microscopic algae. It acts as a bioprotector, drying and dehydrating ants and other insects without harming plants, animals, or people.
neem oil It is a natural repellent and insecticide that can be applied diluted in water to plants and substrate. It is effective both in repelling ants and preventing associated pests.
Preventive measures to prevent ants from returning
- Keep the plant area free of organic debris such as dry leaves, fallen fruit, and weeds. These debris provide shelter and food for ants.
- Avoid excessive watering, since humidity favors the proliferation of ants and other insects.
- Periodically check the base and back of the leaves to detect and eliminate pests such as aphids, mealybugs or whiteflies.
- Cut off access to plants and gardens sealing cracks and gaps where ants can enter from the outside.
What to do if the ants persist?
If after applying natural and preventive remedies the population continues to grow, there are specific ecological insecticides such as those based on potassium soap or diatomaceous earth. Always follow the recommended dosages and apply during the coolest hours of the day to maximize their effectiveness and protect beneficial insects.
Ant control on plants is a task that can be easily done with consistency and using sustainable and natural solutionsTake advantage of your garden's biodiversity, maintain preventive habits, and apply home remedies tailored to your specific situation. This way, you'll not only prevent damage to your plants and crops, but also foster a healthy and balanced environment in your green surroundings, with the lowest possible environmental impact.
