Is there anything I can do to stop the stairs in my house from squeaking?
There is. Find the offending step (or steps) and sprinkle some talcum powder into the noisy joint between the tread and the riser. For a more permanent solution, if you can get at the back of your stairs, you can repair them by driving nails from underneath through the riser and into the tread at an angle; this will make them hold better.
