I have waited till now to post this because I have been trying several methods to see which one is not only effective but which one is the easiest, most reliable and longest lasting.
After trying numerous methods researched on the internet and in books, I have found that by taking Vaseline and spreading it on the pole that holds the feeder works perfect. If you put a good coating all around the pole and covering about 3 inches in length about half way up the pole does the trick. Make sure to make the coating at least close to a 1/8 of an inch thick or thicker because it acts as kind of a quicksand to them. It is very simple and takes only a couple of minutes and will last for weeks, even through 90 degree+ temps and severe thunder storms. Make sure that nothing is touching the pole above where the Vaseline is applied or for sure the ants will find this bridge to circumvent your Vaseline road block. CAUTION! do NOT apply above the feeder as it will run down the pole some in the heat and would end up on the feeder. Reapply when the thickness gets below 1/8 of an inch.
