It is a well known fact that you will need to change the nectar solution in your hummingbird feeder regularly. Just what is meant by regularly? This is something that my mom and so many others have wondered about and never quite had the definitive answer to before. This post will provide you with the information you seek. Well, what is meant by regularly depends on where you live and the temperature you are experiencing in your area of the country.
Below you will find a chart that offers some guidelines as to how often the nectar solution should be changed. The temperatures listed below are only guidelines and are not exact. The information in this list is not my own and comes from the website How to Enjoy Hummingbirds.
High temperatures…………Change nectar after
71-75……………………………6 days
76-80……………………………5 days
81-84……………………………4 days
85-88……………………………3 days
89-92……………………………2 days
93+………………………………change daily
You should keep an eye on your feeders and make sure that the nectar solution does not appear to be cloudy or appear to contain mold. If this occurs, immediately clean your feeders well and fill once more with fresh nectar solution. Another simple rule of thumb is to clean your feeders every single time that they need to be filled once again. It is far better to make sure that your feeders are clean and the nectar solution fresh rather then risking causing any harm to the hummingbirds that we all so enjoy.
