These floating stones help to prevent bees from drowning in syrup or water feeders
The floating stones are placed on the bottom of the existing feeding bucket or feeding device. The bottom should be completely covered with floating stones. The syrup is then added. Now the stones float on the surface and the bees can take the food without drowning. Cleaning after use is usually not necessary. If desired, the stones can be washed off with water after use and stored for the next year.
