(A) Hygiene / Management

Although frequently inaccessible and difficult to destroy, ants’ nests must be eradicated if infestations are to be successfully controlled. The nests of Black ants can be located by following their trails. Potential food sources should be identified and protected from attack.

(B) Insecticidal control

Insecticide treatments can be applied in and around the nest and should aim to ensure that a residual film of insecticide is maintained at strategic points, for example points of entry to buildings, such as doors, windows, ventilators, ducts, and drains. Wall / floor junctions, ant runs and all other harbourages should be treated, using the product according to the label directions. Particular attention should be given to small insignificant cracks which may be major points of entry for the ants. Insecticidal baits too, can be used around the entry points.
