Anton, I don't think those traps have pheromone bait strong enough to extend 
more than 25-50' from the trap, so I wouldn't worry too much about attracting 
bugs from outside your yard.

I use the wing traps from Great Lakes with a CM lure in it, and it works 
well.  This last year I trapped zero, the mating disruption program I had 
started a few years ago finally reaped dividends.   The previous years I had 
many in the traps as well as in the fruits.
