Vaseline keeps the ants away

I set up our Hummingbird feeder on one of those metal poles (Shepherd’s Staff, I think they are called) and was pleased to see the little birds sipping away at the sweet water.

When i went to clean the feeder and refill the liquid, I noticed there were tiny ants in the remaining water inside the bottle as well as all along the pole.

So I loaded the pole with Vaseline just before the curve started where the feeder hung.  I smeared about three inches up on the pole.  Worked like a charm!

Now if I could just figure out a way to get rid of those carpenter bees that keep making holes on our wooden deck.  They hover a lot so I just keep swatting them with a fly swatter and killing them.
