Kerosene.
Lots and lots and lots of gallons of kerosene.
Paint the walls with kerosene. Use masks and oxygen tanks if you have to.
But don't light or torch anything. Everything that relies on oxygen should fail to enjoy the place that was doused in Kerosene.
And move away for one week. It worked for termites in my case. You can do one room at a time if you are short on options, which I did.
Biting the hand that feeds IT
