EDIT: Let’s cool it with the downvotes, dudes. We’re not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don’t believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I’m sure almost everybody has something to add.
The attempts to measure dark matter directly have gotten incredibly sensitive and still haven’t found anything.

Multiple experiments to detect dark matter directly here on earth have been constructed. They expected a handful of detections a year given the estimates of local dark matter densities. Those experiments have not yielded any detections. This sets very restrictive limits on candidates for particle like dark matter.
I’m fully aware of astronomical observations that suggest the need for dark matter. That’s not what I was referring to.
So far, astronomical observations are all we have, the lack of terrestrial observations have only been able to elliminate candidate particles, not measure them.
