Here's what I do for spider maintenance a couple of times a week. This is my mundane routine.

I got my tubes from US Plastic, somewhere. It's a huge site, I haven't found the right link yet.

I picked up the cube-shaped ones on Amazon.

On a budget? These ziploc containers are cheap.

A vial of Drosophila vestigial winged flies is $9.

Breed your own flies with Drosophila medium. Just add water.

Oh, and a few grains of yeast.

For the bigger spiders (not shown in the video) I use these sterilite containers.
