We've spent years and years eliminating the low hanging fruit -- as one should do first -- but that doesn't resolve the dark matter problem at all. The more exotic types are really, really hard to detect in particle colliders the scale of which we can readily build.
It would be nice to say "we looked for it, but it doesn't seem to exist", but we can't say that. We're nowhere close to saying that. Detecting particles that are hypothesized to only interact via gravity is insanely difficult.
