I've gone through so many hummingbird feeders that the hummingbirds have stopped being cautious when a new one appears.  I've tried decorative blown-glass ones, lightweight plastics ones, and glass/plastic combo ones manufactured by various companies, including Garden Treasures and this one, Perky Pets.  I've tried models with built-in ant moats and others with bee guards.  If I could keep away ants, then I couldn't dissuade the bees.  And ultimately, each model either leaked or crashed to the ground due to the included but inadequate hanging methods.  Finally, however, I think I've found The One, although I combine it with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Nectar-Protector/dp/B000U9Q4X8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Nectar Protector</a>&nbsp;to keep ants away -- more on that later.
