Welp, I just saw we have a special species of mole confined to Europe alone it seems.What are your deterrent methods? I can give them a try as I'm sure I have plenty more of these guys around.
Might be why they are under protection.
My parents had a mole problem a while back and solved it with alcohol-soaked rags we put inside the tunnels every few meters. Took a bit of patience and tenacity but it or they fucked off to another place.
Also added some wind chimes that transferred the waves to the ground, so far none came back.
But that might not work for the species terrorizing ya, dunno.
