Most experts suggest only filling it about halfway full – sure, it means more work on your part, but then it's less likely the nectar will get a chance to mold. However, if you have so many hummingbirds you can barely keep up, go ahead and fill it all the way up. Take a clean, empty 2-liter bottle to hold the rest of the nectar and keep it in the refrigerator. It will keep for around a week as long as you keep it in a cold, dry location. Do this more often if you notice mold growth or fermentation. Generally speaking, nectar deterioration will be controlled by the outside temperature. Here's a brief rundown of how it works:  Temperature: 71-75°F (23-25°C); change every	6 days Temperature: 76-80°F (25-27°C); change every 5 days Temperature: 81-84°F (27-29°C); change every 4 days Temperature: 85-88°F (29-31°C); change every 3 days Temperature: 89-92°F (31-33°C); change every 2 days Temperature: 93°F+ (33°C+); change daily Do this every time before you add new hummingbird nectar to the feeder.  Old nectar will mold, resulting in white strings and sometimes even black, moldy spots, so be sure to get rid of the mold regularly.  Sometimes you can get away with only washing it with hot water, if you take it apart and are diligent. However, only do this if no mold whatsoever is present. Most feeders come apart easily just for this reason. If you do use vinegar, make sure the vinegar odor is gone before you replace the nectar. Flush any vinegar residue with a hot water rinse.
