In the garden, one of the common problems we can encounter is the presence of an anthill. To eliminate it in an effective and environmentally friendly way, there are several methods we can adopt.
In this article we will explore some practical and sustainable solutions to manage the presence of ants in our green space.
Why it is important to eliminate anthills in the garden
Ants are incredibly organized social insects and essential for theecosystem.
However, when ant hills establish themselves in your garden, they can cause damage to plants and make outdoor maintenance difficult.
This is why it is crucial to address the problem in an effective and environmentally friendly way.
Natural Methods to Eliminate Anthills
- Boiling water: Pouring boiling water directly onto the anthill is a simple but effective method. However, be careful not to damage surrounding plants or get burned.
- Terra diatomacea: This natural powder is composed of fossilized remains of microscopic algae. Sprinkle it around the anthill and on the ant paths. The abrasive particles will damage the ants’ exoskeleton, causing dehydration and death.
- Repellent plants: Plant peppermint, lavender and thyme near the anthill. These plants give off aromas that repel ants, helping to keep them away.
- Vinegar: Mix equal parts vinegar and water and spray the solution on the anthill and areas frequented by ants. This method also helps eliminate trace pheromones that ants use to communicate.
- Bicarbonate and sugar: Mix equal parts baking soda and sugar and sprinkle the mixture around the anthill. The ants will be attracted to the sugar and will also ingest the bicarbonate, which will react with stomach acids, killing them.
Biological Methods to Control Anthills
- Entomopathogenic nematodes: These tiny worms parasitize and kill ants by releasing bacteria into their bodies. Purchase nematodes specifically for ant control and apply them according to the manufacturer’s instructions.
- Predatory insects: Encourages the presence of spiders, ladybugs and parasitoid wasps, natural predators of ants. Plant native flowers and avoid using chemical insecticides to encourage these insects.
Chemical Methods to Eliminate Anthills
- Poisoned bait: Contain low toxicity insecticides mixed with sugary substances. The worker ants carry the poisoned bait into the colony, where it is consumed by the other members, including the queen, resulting in the destruction of the entire colony.
- Powder or liquid insecticides: If other methods don’t work, you can consider using chemical insecticides. Apply them directly to the anthill following the manufacturer’s instructions. Choose a product specifically designed for ants and follow safety precautions.
Prevention and Maintenance to Avoid Anthills
- Eliminate food sources: Clean food waste regularly, close garbage cans tightly and store food in airtight containers to avoid attracting ants.
- Control aphid populations: Aphids secrete a sugary substance called honeydew, which attracts ants. Controlling aphid populations in your outdoor spaces will reduce the attraction of ants.
- Inspect the garden regularly: Regularly check for ant hills or signs of ant activity. Act quickly to treat problems as they arise to prevent colonies from establishing and spreading.
- Plant maintenance: Prune tree and shrub branches that touch your home to prevent ants from gaining access. Keep plants that attract ants away from entrances to your home.
