Abrégé

Disclosed is an insect repulsion and/or barrier arrangement (10) and a method for repelling insects (2) and/or for preventing the passage of insects (2) through a defined opening (12) or surface (9). The insect repulsion and/or barrier arrangement (10) comprises at least one opening (12) located within a wall (8) or a surface which is largely permeable to ambient air. The insect repulsion and/or barrier arrangement (10) is equipped with devices (16) for preventing insects from passing through the opening (12) and/or for repelling insects when approaching the opening (12) and/or the devices (16). The devices (16) have at least two electrodes (18), whereby different electrical potentials are applied to or can be applied to the at least two electrodes (18), which are arranged within and/or on the edge and/or outside of the opening (12) and in proximity to the opening (12) in a definable distance from each other. The at least two electrodes (18) are arranged in such a way that an electrical field (28) is formed between the at least two electrodes (18), which electrical field (28) is either permanently or cyclically increasing and decreasing or which is present at intervals of time with interruptions. The permanent electrical field (28) or cyclically increasing and decreasing electrical field (28) or the electrical field (28) which is present at intervals with interruptions, rejects and/or repels insects approaching the electrical field (28) and/or prevents insects approaching the electrical field (28) from passing through the opening (12).
