No doubt, ants prove to be beneficial to the gardener by feeding on destructive garden pests such as caterpillars, spiders and small insects. But, some species like black garden ants live together with the aphids (for their honeydew). In such a case, they are inviting a notorious pest in the garden. So, how do you get rid of them?
Though you can find several poisons for killing them, do not consider using commercial products. Rather you can rely on effective homemade remedies which are discussed here:
Pour Boiling Water
This method of drowning the garden ants with boiling water is practical if the number is less. For one mound, you require about 3 gallons of boiling water. Accordingly, pour boiling water in their hills and kill them.
Use Citrus Peelings
Collect citrus peelings (orange, lemon, etc.) and ground them by using adequate amount of water. Remove the liquid concoction and spray it over the mound. This method is an effective natural remedy for getting rid of carpenter and other garden ants.
Sugar attracts them, and as they feed on the mixture and the borax kills them. By following this method, you will be successful in getting rid of sugar ants.
Grits or hot cereals are a perfect choice for getting rid of ants in the yard and garden. As per your choice, purchase any brand of hot cereal from the market and sprinkle it in the garden, especially in the mounds and hills. After they feed on this hot cereal, it expands in the stomach and kills them.
In case, these methods do not work, you can use insecticidal sprays. It is not a natural way but, if nothing is working, you can consult professional pest control services and use chemical insecticides.
