Will blood worm survive in my tank?

Yes, they can survive. I don't understand why you're worried though. If the worms thrive, they're an indicator that your system is healthy and they'll provide a steady food source for your fish.
I seed my tanks with scuds (amphipods) to serve the same function. They eat passed over foods, food that gets into places the fish can't, and the fish have a frequent snack of the scuds that venture out into the open.

Good point but like I stated before I am terrified of worms I dont want to open up my filter one day and see hundreds or thousands of these worms in there. Is there anything I can do if they do get out of control?

I know that since I need a disclaimer, I really shouldn't probably say this, and I hope you can forgive me, but....
