Whether you are an avid hummingbird enthusiast or if you are a new fan of hummingbird watching, it is important to be aware that your hummingbird feeders will need to be refilled quite frequently. With this in mind, you may wish to make a fairly large batch of homemade nectar solution ahead of time. Regardless of if you choose to make your own nectar solution or to buy it, you must know just how long it can be kept in the refrigerator and how to store it properly and safely.
Until you have some idea of the number of hummingbirds that will be frequenting your feeders, I would recommend making just enough nectar solution to refill your feeders at the given moment. This helps ensure that the solution is fresh at the time your feeders are replenished.
Once you have a better idea of the number of hummingbirds that will likely be visiting your feeders and with what amount of regularity this will likely occur, you may then decide to mix up a larger batch of nectar solution. This homemade nectar solution can be stored in your refrigerator for up to two weeks. It is important that the nectar solution be properly labeled to ensure that the contents of the container are clearly known to all.
In what type of container should any unused homemade nectar solution be stored? It has been my own experience that either empty milk containers or empty two liter soda bottles seem to work quite well. Another suggestion would be a glass canning jar with a tight fitting lid.
If you should choose to use packaged nectar solution rather then making your own, please be sure and follow the label’s own instructions concerning how to safely store it properly.
A final word of caution, regardless of if you make your own homemade nectar solution or you choose to use packaged nectar solution, if you have any doubt as to whether or not the solution is still safe or not please discard it as a precaution. If the mixture is discolored, foul-smelling or cloudy this would indicate that the mixture has spoiled and must be disposed of immediately.
