Critter, also if you have eves you can hang the feeder from, it usually does the job to keep the ants from finding them. You can use chain to get the feeder down to a level you can reach it w/o having to have a step stool to get to it. I have the Humzingers too with the ant moats but often it dries up with our hot weather & I still don't get any ants in them. I have one hanging from a shepherd's hook & it does good too.
I like hanging from the eves b/c it's close to the house & I can place them in front of windows the better to watch them even when inside.
