Annoyed by a squeaky floorboard? The answer could be as easy as a little cornflour.

According to weblog WonderHowTo:
While this only applies to wooden floorboards that don’t have carpet on top, you can also try fixing the squeak on your floor by dusting cornstarch [cornflour] in-between the floor boards to prevent the friction that causes the creak.
Floorboards can change sizes when they contract and expand, typically due to changes in humidity. This change in size causes some of the boards to rub up against nails or each other, creating the squeak that you hear. The idea with the cornflour is to “lubricate” the sides to silence the squeaking.
