Oh my god.

It’s in the wall.

We’re going to have to call a builder or something.

Edit: We are not the only people to have this problem.

• Thriftyfun.com suggests we wait & the smell will dissipate.
• This pest control company in the US will do it but they cut in through the plasterboard.
• Help.com people suggest aromatherapy oils (is there anything aromatherapy won’t cure?) and waiting it out. That or a sledgehammer.
• Maggots? It doesn’t bear thinking about!
• And this smell lasted 8 months or more.

I’m going to check out pest removal companies. Alive or dead, do you think it will make a difference to them?
