We feed them all summer. It's important to remove the feeders at migration time, or they tend to stick around too far into cold weather to survive the trip south. Clear feeding solutions are available, and if you use the feeders with the red "flowers" at the feeding points it attracts them just as effectively as the big red globe of liquid does. Watching several hummers dogfighting over one specific feeding point while ignoring several others is amusing- - - - -they put on a show that would put the Red Baron to shame!
We use a big iron "Shepherd's crook" hanger to put the feeders where they're easily visible from windows, and wrap a strip of flypaper around the upright to keep ants from climbing the pole and contaminating the feeding liquid.
