Salifert makes Flat Worm Exit that can take care of the problem. There are plenty of threads that talk about the "do's & don't s" of using the product.
are they red or clear? I'm pretty sure that the clear ones are fine to have in your tank. The red ones you want to siphon out as many as you can and use something like flatworm exit. Be careful to get as many as possible out of the tank prior to using flatworm exit though, the last thing you want is a whole tun of dead flatworms in the tank.
