Entrance Water Dispenser. Just add a bottle of water.
“We use these in our top bar hive. With a one liter bottle they are the correct size to fit under the top bars. Note. the hive must be level for these to work. but for the price they work well. We change out the bottle and feeder as a unit and wash each one between uses. Our bee hive will use a one liter bottle on 1 to 1 syrup in about 2 to 3 days. Just be sure the feeder sits level or very nearly so.
UPDATE: After almost a year of use I still like these. We feed inside a topbar hive so, No robbing! They continue to work well for us. I use 1 liter bottles (Flavored sparkling water bottles) We put them in the dishwasher to clean after use. Will buy again.”
