One way door

[XenEntity]

Anyone have a good one way door type of thing to catch kitchen ants that linger? I have a cage that I want to put them in, then I'll give them some cookie crumbs or something.

I don't have a one way door, but this video shows how it is done without one.

Maybe this would work, or do you want to kill them, a door would probably not do the job, even with a bait.
