I havent had a worm issue to my knowledge yet but if I do I will use the ivermect wormer but that is just my preference, I have seen other posts where people swear by pumpkin seeds and I also think that my pet chicken has a wormer with no egg withdrawel but I am not sure if it is natural. The vet is the sure way to find out but I just check the poop everyday when I give treats, and every now and then I check their vent areas to see if their are any bug issues or anything peeking out at me that shouldnt be there. Good luck I am sure there are others on here with a whole lot more knowledge than I that can give you other options
