Ants in the house and the apartment

Who would want ants as a subtenant? The plague of ants usually begins in the house and the apartment with a few scout ants. Such “scouts” are permanently on the lookout for new food sources for the ant colony and usually enter the house through the garden or via the balcony or terrace. If the intruders find what they are looking for, so-called trace pheromones mark the path to the food source in the kitchen or pantry. The result is lengthy and trails along which house ants can spread throughout the house in the kitchen.

In addition to ant trails, other traces can indicate an ant infestation in the house or apartment: Flying ants can be observed during swarming times. Visible damage to buildings from wood ants, which like to create their nests in built-in wood or insulating material, is also possible. Crumbs from materials such as wood and nest residue can therefore be an indication of an infestation.

An accumulation of scale or aphids on plants favours a settlement in the building. Background: ants breed and defend aphids to feed on their sweet excretion, honeydew. Therefore, there are often entire ant nests in flower pots or plant beds – with unpleasant consequences: the ants’ duct systems lose contact between the roots and the soil. Water and nutrients can no longer be absorbed, and the plant dries up and dies.

Ants in the garden

A plague of ants in the garden can mainly be recognised by small earth cones or piles of sand in the lawn, on roadsides and pavement slabs. Such signs indicate an ant’s nest. Most ants in the garden prefer sunny and dry places under stones, in-wall crevices, or sandy soils to build their nests. Here ants feel protected from predators and the weather. Often you can recognise a plague of ants in the garden because the joints of terrace and sidewalk slabs dissolve, and the resulting cavities are suddenly populated by ants. The problem: If, for example, lawn ants or black-grey garden ants appear in too large numbers, these ants become harmful in the garden because they protect plant pests such as aphids, cicadas or scale insects from predators such as ladybugs or hoverflies and lacewings,

In the case of ants on the balcony or terrace, you should always keep an eye out for ant trails. If you discover such a caravan, you need to locate the source and thus the nest to initiate targeted measures to combatants. The nest can also be further away, as ants also climb over several floors of buildings to get to the balcony or terrace – as long as the food source is attractive enough.
