I had a single storey extension built on the side of my house 6 years ago.
There were 3 manhole covers in a line, the extension covered the middle manhole cover (a T-Junction). We anticipated having to allow access via the extension but the Council Officer inspected the site and said it could be capped off - as it would be possible to 'rod' from either end & the extension built atop. The extension was built on piles due to nearby conifers.
Rats got into the wall and the loft of the extension.
I got the drains surveyed and they were relined as there were a number of cracks & holes but the problem persisted.
The builder confirmed that the manhole had been capped off correctly. He sealed off the top off the wall (i.e. between the wall and the loft) with a concrete/glass mixture.
This stopped the rats getting into the loft.
But the rats are still in the walls. I put a lot of poison down, this stops them for a while but we then have to put up with the stench of decaying rats... it is truly horrible, we've got one at the moment.
The only long term solution I can think of is to pump concrete into the lower part of the wall to stop the rats getting into the wall (there is no other access). Not sure how this would be possible what with the insulation material that is already there etc.
Any ideas or similar experiences out there?
