Cellar Bugs

Hi all,
Not sure if you'll know what I'm talking about with cellar bugs. They're also known as sow bugs I think. Grey oval critters that hang around in damp areas. Sometimes you'll come across a mother bug with young underneath.
How the heck do you get rid of these things? I've heard clove oil (tried that, no effect), I've heard that if you clear away any leafy compost-y debris around your house it helps (tried that too, they're still here), and I've also read that if your house is on a cement pad without an adequate moisture barrier, then you'll have them and it's just tough.
This isn't my house, my mom has an inn with rooms on the lower level. Although these bugs are harmless, they really aren't so harmless to a tourist. What can we do to eradicate the nasty buggers?

Worse case I have seen was an expansion joint from the drive way to a garage...it was allowing grass clippings to accumulate, and a population of thousands. Another place in a slab foundation can be the bath trap areas.

Indoors, fog with Raid Fumigators (the type that places the cartridge in water and emits a non-flammable steam) every 4 weeks. Outdoors use a residual spray around the foundation, something that contains cyfluthrin such as Bayer Advanced Home.
