What feeders should I get for my frogs?

I am thinking of isopods, local ones I can catch for now and dwarf whites sooner or later.
Housefly and Bottle fly for a big meal they can catch off the ground.
Maybe some Phoenix worms but it will be so cold here for the next few weeks I doubt they will be ordered soon.
Crickets of course but want to vary the diet a lot more.

Anyone have any other suggestions? I thought about trying to catch some flies with the tried and true meat in a jar method. There should be a lot lower chance of pesticide issues this time of year.

I have even considered culturing my own flies, not something my wife was too thrilled about either but sounded better to her than roaches. I came across an interesting article on doing this and it doesn't seem to be so bad. Not as smelly as I thought they might be but the method is for Bushfly (Musca vetutissima) and not specifically houseflies. I have tried to contact the author to see if this should work for houseflies also. http://www.geckodan.com/articles/Bre...%20Bushfly.pdf that is the site. If anyone has ever tried anything similar please let me know if it worked or didn't work.

Any other suggestions on something I can culture myself or get regularly when it is going to be so cold. Fly pupa ship fine but everything else is gonna have to wait until the weather here gets a bit warmer. The post office is not the fastest at times and I hate to have an order of dead stuff arrive expecting food for my frogs.
