So we know bees like the colors blue, purple and yellow but did you know they are also attracted to fresh water.
Why do bees need fresh water? A lot of the water available to bees is not ideal.
Chlorine - In a suburban environment, we recommend giving your bees fresh water to keep them out of your neighbor's swimming pool. Not only can the water contain chlorine and other contaminants, it may also bother your neighbor.
Larvae Development - Hypopharyngeal glands are less developed in workers starved, poisoned with pesticides and other anaesthetics.  The nurse bees and other bees use these glands to feed the larvae. During 24 hours the queen is able to lay more than 2000 eggs (larvae). That's a lot of mouths to feed!
Easy Ways To Give Honey Bees Water Key Tips For Watering Feature For Bees
Shallow & Wide - Bees don't need a deep bucket, just a small amount where they can't drown.
Corks, Rocks, or twigs - Always place floating wine corks, rocks, or glass pebbles so the bees have a place to get near but not drown in the water
Fresh Water - It is important the water is refreshed every day or every other day, so under a leaky outdoor faucet is a good spot to place a watering feature.
Best Honey Bee Watering Ideas
Frisbee With Rocks - Put a frisbee full of clean rocks (find them in your yard) underneath a faucet outside, turn the faucet on so it drips once per minute. Over the day it will fill up and provide fresh water for the bees.
Glass Pebbles - Most art stores, dollar stores or Target like stores have those bags of glass pebbles you can buy. Buy 1-2 bags of these pebbles and put them in a large (6 or more inches) but shallow container. Fill this with fresh water daily and place it near your garden or outside in a natural area of your yard. Bonus if you put some water loving plants like horsetail, cattail, water loving ferns, etc
Birdbath - Take over the bird bath and decorate with twigs, rocks, pebbles, and wine corks. Ad some green ferns or moss to add a bit of color.
