Everyone wants a silver bullet, no one wants to have to invest elbow grease; but that’s the underlying trick to long-term pest suppression – making the environment inhospitable to the pest.  Clean up whatever is attracting them, and seal them out.  Prevent their access to food and they’ll starve.  Get rid of clutter and they won’t have a place to hide. Just about any pest we mention can be significantly reduced by these two measures – cleaning up and keeping them out.
