Not water, but nectar. Flowers do not produce a cup of nectar at a time to ferment over then next week.. They produce a fraction of a drop of nectar, which is taken up within hours usually by a bee, wasp, butterfly or hummingbird, so it does not have time to ferment.

I, too, struggle with keeping feeders clean and mold-free, and after cleaning, rinse mine with CS, but then thoroughly wipe them dry, as I'm afraid CS could interfere with hummers' benign bacteria and enzymes.

A quick Google didn’t turn anything up so I thought I’d ask the list:
Do you have any experience or other knowledge to indicate whether CS would be helpful/harmful/neutral do hummingbirds? The reason I ask is mould can be a problem in hummingbird feeders and I was thinking CS might help stop that (not sure on this either, just thought it might inhibit mould too—please correct me if I’ve missed the boat). I’m not sure what kind of digestive system hummingbirds have (their diet is nectar and insects) and whether CS would be compatible with their needs or not. All feedback/ideas are welcome. - Walter
