On Kalos Route 4, using your Dowsing machine you can find about 3 Honies in the mazes. If you don't want to do all that, buy a few Pokeballs if you don't have any and catch a Combee, any level in Route 4. They are common in the Yellow flowers. Use it's Sweet Scent attack on the grass you want to get a Pokemon Horde in by going to the Pokemon tab in the X button menu, tapping Combee, tapping 'USE A MOVE', and sweet scent. If it isn't there, catch another Combee. I got my first Combee and Sweet Scent on my first try.
