You can go to the pet store and get de-wormers your self. Safeguard or Panacur-c will get rid of pretty much everything, it is safe and mild, it comes in a pouch with powder , you mix in the food. It comes 3 doses you give over the course of 3 days and you do not see worms anymore !
You can also give Pyrantel but it is not as broad as the other 2 i mentioned. I would start it right away !
