mantis or not

[fishguyxd]

I have seen what I think is a mantis (From pics on the web.)
this thing moved Fast ! then stopped and got in a corner then in and out of the LR. Looked like it had a lots of legs but it was not flat looked ,like it had two little horns

Are these good /bad what do they eat? or how do i get rid of it .

I can't get any pics just yet.

I have also heard a clicking noise that was not there before.
