There is a alternate approach but it hinges on how dimwitted your uninvited guests are. STEP 1, build a replica garage some distance from your location. STEP 2, fill garage with substantial amount of TNT. STEP 3, as a lure I will send you a smokin hot female mouse named Fang Fang. I think you know where this is going. I suggest that the site chosen would be ideal for a future coy pond or in ground pool.
