Cockroach, how to get rid?

[compact]

Just moved in to a house a few weeks back.
Old Victorian terrace.

I have noticed a few cockroaches in the kitchen (NOT HAPPY)

The kitchen does not have a cellar.
It has Lino down (laid a year ago apparently)

They seem to be coming from under skirting board, where there is a gap between the Lino and the board.

Has anyone dealt with this in the past (you can use fake names to hide embarrassment, Miss Bucket maybe

Any ideas what I can do?

I have seen traps, powder and spray.

How can I get rid of them?
Rip of skirting boards? Spray? fill holes with pollyfilla?

I need help... (can't bring a lady back and have her see one...)
