Keeps the birds unfortunately absolutely not from nesting or landing from!

I had the spikes brought to birds from nesting and land on the outwardly projecting abhzuhalten rafters because the birds unfortunately left enormous damage to the facade. My hope was consulted this problem the past but very disappointed. The birds walk between and on the spikes and use these even so the nesting material keeps safe. All in all a complete bad buy! Mag might disturb pigeons, all species of birds that are only a little less let that not deter purely.
