After talking to a lot of people, I finally got off my butt and made an electronic aspirator using a cheap keyboard vacuum.
I needed a cheap keyboard vacuum (less than $20 on Amazon), plastic pill bottle, drill with 3/8 inch drill bit (to drill two holes in the pill bottle lid), 1/4 inch tubing (exterior is 3/8 of an inch), a very short length of 1/2 inch exterior tubing (size adaptor between vacuum's opening and the 1/4 inch tubing), and tape to seal gaps (I used three types but electrical does seem to work best). Oh and some Fluon to coat the pill bottle.
The vacuum is not very powerful but it could pick up Veromessor pergandei (which are pretty small) while I cleaned up some of their trash.
It could also pick up Camponotus fragilis, with effort. The fraggles are bigger and heavier and don't fit very well into 1/4 inch tubing, but will eventually get sucked in.
I did find that if I wasn't holding things just right, some ants would get sucked into the vacuum's dust bin.
Thanks to the discord people for their building input/suggestions.

I'm sure a normal lung-powered aspirator is more powerful (never used one on ants). However, with an electronic one, it can maintain continuous suction. Even if one pass doesn't pick up an ant, you can make multiple passes without having to think about it. The main problem I had was holding the vacuum AND the pill bottle (has to be upright, otherwise ants get sucked into the vacuum), AND holding the nozzle at the same time WHILE also mucking around with formicaria lids and trash and whatnot. But you can pretty easily just hold the vacuum tucked under your arm or make some kind of stand for it. Again, most important part is having the collection container upright so you aren't sucking ants into the vacuum itself. Of course, this is so weak that they are just fine even if you do.
I did wind up using my ant paint brush a bit to clean up ants after the suctioning.
All that said, I looked at the gross stuff all over the vacuum cleaner filter afterward, and I was glad I wasn't using my lungs to suck that stuff in.
Eventually I hope to also get a blowing aspirator ... that would probably be lung powered, but at least it won't involve inhaling ant trash.
