Don't want to jinx it, but we have been lucky. Our neighbour not so much as he had a fox and her cubs under theirs!
It has been there now about 11 years. The base it is on is wood, but the decking non wood. No one can tell and it still looks like new 11 years later.
Yep we ended up with Rats nesting under the decking. Obviously we had 2 options.
1) Call in a professional pest controller, pay the man his damn money and just move on.
2) Claim that the man quoted a ridiculous price for what is a "piece of piss job." Spend a ridiculous amount of money on an air rifle and scope. Realise that rats are primarily nocturnal and you don't have a hope in the dark. Spend even more money buying a night scope and pretending you're Mark Wahlberg in shooter. The rats continue to have a long and fruitful life, mocking any attempts at their genocide. Until Mrs Lincoln fed up with my shooting spot taking up 40% of the front room, secretly called rento-kill in while I was at work.
Guess which option we did?
