Bee feeders are used when the temperatures rise or fall too much for foraging. Generally, bees will not forage if the weather is hotter than 100 degrees or below 57 degrees Fahrenheit. Bee feeders help to supplement them and keep them strong until the weather is good enough for them to forage again. Rocky Mountain Bee Supply offers a variety of bee feeders depending on your needs to provide your bees with the sustenance they need.
