Weaver ants help to protect your fruit and nuts from fruit flies and many other pests. If you don’t have weaver ants in your orchard yet, collect all the nests from an ant colony and transfer them to one of your fruit trees. Help the ants to spread to more trees by connecting neighbouring trees with a string or stick. If ants from neighbouring trees fight, they are from different colonies and should be separated. Cut any branches that connect both trees. Apply ash to your arms and feet, or to the branch on which you will stand, to pick the fruit.
