In the garden, ants feed on insect pests such as caterpillars and protect against aphids, spiders or worms. However, when they become invasive, it is best to eradicate them.
The best way to get rid of ants without killing the surrounding plants is not to use insecticides, and therefore to favor natural methods.
The best prevention: control aphids
Since aphids inevitably attract ants, take action against them before you see colonies of ants set up, which in turn will support aphid colonies. Soapy water is your best bet in the fight against aphids, even in the orchard, when your trees are invaded by these undesirables.
Why eliminate ants?
Ants are fond of sugar. Since aphids and mealy bugs feed on sap that they secrete in the form of very sweet honeydew, ants help them produce it.
By rubbing against these insects, they accelerate the production of honeydew. They also protect aphids and mealy bugs by hiding them from their predators.
