The invention relates to a device (1) for combating
infestation with ectoparasites, comprising a plurality of parasite traps (2) which are to be distributed in the spatial region (3) of the
infestation and which each have a plurality of slip holes (7) arranged next to one another, wherein each of the slip holes (7) has a free cross-section with a
maximum diameter and a minimum
diameter in the
diameter range of 0.5 to 5 mm, the majority of the slip holes (7) are formed between a first
electrode (10) provided with a
dielectric shielding (8) and a second
electrode (10) that can be removed from the first
electrode (9), and the first electrodes (9) and the second electrodes (10) of the plurality of parasite traps (2) are wired or can be wired to a
high voltage source (6), wherein the
high voltage source (6) is designed to apply a
voltage (22) of this type of varying amplitude between the first electrodes (9) and second electrodes (10) such that
dielectric barrier
discharge occurs in the slip holes (7).
