Several days ago, a long interview with the former Czech ambassador to Moscow, Vítězslav Pivoňka, appeared in Czech newspapers. Unfortunately it is mostly paywalled. [0]

As you could expect, bugs everywhere, but some were used for intimidation. E.g. he says, on a weekend morning, we were still in bed with my wife, when a cuckoo started cuckooing out of a wall. Yeah, it was a bug, and it was meant to emit sound and make you more nervous: "we know about everything that happens in your bed".

He said that the Russians never cross the red line of actually physically manhandling diplomats, but as far as bugs and psychological pressure go, there is nothing off-limits.
