Q: I have several hummingbird feeders that are visited a lot but I have to be out of town for seven days. What can I put in the feeders that will prevent them from getting moldy?
A: Nothing would prevent mold except absolutely sterile containers and liquid. I think those would be impossible for a homeowner to achieve. Put some filled feeders in your refrigerator and ask a friend to come by and put them out after three days. They won’t get moldy if kept cold.
