Dealing with Loose players

Hi guys I'm looking for advice on how to deal with Loose players. In my home game people always limp and call with far too wide ranges so the usually at least 3 people see the flop even with a raise preflop. I know that usually you should play tight preflop and only play good hands but as I tried that people noticed really fast and over folded. Up to now I have been bluffing with quite some frequency and have had some success with it but I doubt that this is really the strategy which wins the most money. Do you guys have any tips on how to improve my game?

(P.S. I am a pretty bad player but for that game I'm good. And yes I have been limping but I only put that at the end because I am absolutely not proud of that. But I do believe that to some frequency it can be profitable in this game. Any insight on this?)
