Hey Lemouth, this definitely answers my question!
Your post has been made a few days ago but I can remember you mentioned that these particles are hard to detect. My question would be: Why? Is it not easier to detect an elephant instead of a mosquito?
And here it's godzilla ;-)

Dark matter direct detection rely on the interactions of dark matter with normal matter. Here, we have an elephant but very feebly interacting. Therefore, we can't see it because it just does not interact at all with the detector.
