How often should I change nectar and clean the feeders?
The feeders and base should be cleaned every 2 to 3 days depending on the heat. In 90® weather, change every day. Check often to be sure nectar is not cloudy. Bacteria and mold can build up and, If the nectar is bad, the hummers may not return. Use warm soapy water and rinse well. Use the Hummer’s Galore curved bristle brush to clean inside the feeder all the way to the bottom.
