Re: fruit fly media

[Rjga at aol_com]

The medium should be dry enough that it doesn't easily slip out when you 
shake the jar sideways or upside down. When the medium gets wet, it's 
impossible to control. I try to use pretty dry media, and add paper toweling 
both to absorb excess moisture and for the flies to climb upon. They also lay 
eggs on the paper, which is useful for mailing to other people. I stopped 
keeping frogs, so I stopped keeping flies. But they are the best possible 
food for killies. The biggest jars I used were pint mason jars, but 1/2 pint 
jars with narrow necks are better for control. Haven't seen these types of 
jars in a while. They resemble the old time 1/2 pint cream bottles from the 
dairy, the ones with the paper lift up tab.  Narrow necks make using cotton 
balls easy..
