How to Find a Garden Ants Nest
Unfortunately, the nests of ants are sometimes difficult to access and just as difficult to destroy. You can try to locate the nest by following the trails of the ants. They will move to and from the nest to find and bring back food. Small piles of soil around holes in the earth or at the base of walls are indicators of a garden ants nest. If the heaps of earth are bigger, they can cause damage to low-growing plants. Larger ant hills may indicate a larger colony. Ants will cultivate other pests like greenflies, because the ants eat the honeydew which the aphids secrete. If you discover plants damage caused by these aphids, it is likely that there is an ant farm nearby.
If you find their entry point to your house, you can try to seal it off to keep the ants from getting inside. Try to avoid disturbing ant hills or nests. Red ants or European fire ants are not as aggressive as their South American cousins, but they can still attack if you disturb them or their nest. Red ants can rapidly swarm and have stings. Usually this sting causes the same amount of irritation and swelling as a nettle sting would. However, some people may have serious allergies to ant stings. For this reason, if you have an infestation of red ants, seek professional help immediately to carry out garden ants control for you.
