The house we've just bought has a large decking area out back, and I'm told by the neighbour that he's pretty sure there are rats under there. Having googled 'rats and decking' it seems highly likely as it's a well known problem with decking.
We are going to be having a lot of building work done before we move in, part of which will involve ripping up one section of decking to make way for an extension. My question is, while we have easy access to underneath, is there anything we can do to get rid of the rats and keep them away? I've read that poison is not especially effective and also not a great idea with kids/pets around, and that traps are generally ineffective. And presumably they would come back anyway.
Is the only real option going to be to get rid of the decking? I'd rather not unless I have to.
