mosquitos in water barrels
Hello Fellow Gardeners!
We are looking for ways to control mosquitos in water barrels, with a
preference for organic/non-toxic ways.
I have heard of putting vegetable oil on the surface of the water. Has
anyone tried this? What's a recommended volume of oil?
Also, I know bleach is an option, but don't know how much should be added
per gallon of water. Do you?
Any other ideas?
Many thanks, and Happy Gardening!
