Spider Control on Glazed Balconies in Visp

Retrofitting balcony glazing in Visp is governed by Art. 34 of the building and zoning regulations. On multi-family buildings, balcony glazing is only approved as part of an overall design concept for the relevant facade, and the building permit application must include the property owners' written consent or their authorisation. Art. 33 additionally permits unheated, single-storey conservatories on south, west and east facades under certain conditions.

I therefore assume that in a multi-family building in Visp, practically all the glazed balconies share the same construction, with the same running tracks, profiles and rebates. If one balcony is infested, the identically built neighbouring balconies usually are too.

With glazed structures, webs and egg sacs often sit in the running tracks of the folding and sliding sashes and in the upper profiles, sheltered from wind and barely reachable from outside. Before I apply the long-term treatment, I remove them mechanically. For On tall facades, I use rope access when needed.

At a multi-family building, planning goes through the property management or the owners' association, and I treat the whole glazed facade in a single appointment rather than balcony by balcony. Elsewhere, the process depends on different building requirements, such as the north-south gable orientation in St. German.
