Since my bee water is full of mosquitos, and oil on the water is the only way I know to kill them, "cannot change water" will fgmo help or harm the bees. Will they die when gathering water, or will they take it back to the hive and kill VM? Or neither?
I haven't tried this, but the local university bee lab keeps a pile of compost near their hives and keeps it wet. the bee's use it a lot for water. their idea is they get trace elements from it. I figured you could also take a 5 gallon bucket and fill it with compost then add maybe 2 or 3 gallons of water. that should stay damp a long time but there wouldn't be a puddle for mosquitos.
Ditto Michael's suggestion to use BT...the formula for mosquitos is also called "mosquito dunks". Each dunk lasts about 30 days and you can break them into smaller pieces to use in birdbaths, small reflecting ponds and other nonmoving water.
