What is the trick to make bugs removeable from a vehicle?

I use Mequires synthetic spray wax. Best of the quick waxes. Just put it on a clean windshield and use a micro fiber to remove it. I generally do it twice.
I use it on all the glass,on the Mercedes. Bugs and stuff come off easier.
I just spray them off. I'm not saying bugs still won't make a mess but they come off easier as does dust.
