The One Gallon Pail Feeder is a great way to feed bees. The One Gallon Pail Feeder fits completely inside the hive, eliminates drowning and robbing. Simply place the One Gallon Pail Feeder over the hole in the inner cover, place an empty super around the Pail Feeder, and then the top cover. The One Gallon Pail Feeder is made of HDPE plastic. The lid has a one inch screen in the center for the bees to extract the syrup. The feeder has a metal handle and can be transported with the lid upright and inverted just before being placed on the hive. A small amount of syrup will drain out of the feeder when the pail is first inverted until the pressure equalizes inside the feeder. It will take longer for the pressure to equalize in a partially full feeder than in a full feeder.
