Not really, a black hole is not different orbitally than any other object with mass. You could replace all the stars in the Milky Way with a black hole of the same mass and basically nothing would change for us except not having starlight. Black holes suck everything in the same way that stars and planets do - unless you are literally heading right towards it, if the relative velocity is high, you would just move past each other.

A tiny black hole would not have enough mass to pull in a significant amount of matter and would just pass through the earth if it were coming from space. If the black hole were created on earth it would need a lot more mass than a collider could give it to do anything funky.
