Hi Adrian, maybe an alternative is the system BIRD FREE with a kind of “fire-effect”. I have no practical experiences with this system, but it is offered for professional pest control companies from KILLGERM longer time. See https://www.ornitec.de/produkte/bird-free-gel/
Other alternative could be “Laser technology” but it probably bring the same problems with the neighborhood as sound systems: See https://pps-vertrieb.de/agrilaserr-autonomic.html or https://pps-vertrieb.de/vogelabwehr/cat-lasertechnologie_222.html Best Stephan Stephan Biebl Ingenieurbüro für Holzschutz 83671 Benediktbeuern Germany www.holzwurmfluesterer.de Von: 'Adrian Doyle' via MuseumPests <pestlist@googlegroups.com> Gesendet: Mittwoch, 21.

It has been suggested that the birds see it as a ‘lake’ and we have never had success with things like shock systems or brining a hawk around the site Our pest control company has recommended high frequency acoustic scarers I don’t have any experience of them so have any of you used them and is it worth the investment?
