Water is the answer my friend.

Never had them in my yard, not that I noticed anyway. Buried an old trash can for a water feature. Bam. Dragonflies.

I have 3 other ponds. One is a $25 Home Depot pond and the other is a thrift-store witch's cauldron. They all have a couple of goldfish in them, native water plants, and the trash can pond has a solar cell running a 12V water pump.
