Fleas/feral cats

Question
I hope you can help me with this. I have a feral female cat that has had babies and one of them survived and is also feral cat in my yard so I have 2 feral cats now. Is there some for of herb or natural food product that I can feed these feral cats that will rid them of fleas. They come to the door to be fed but I have tried trapping them and they will not get in the trap. I have trapped others. These 2 feral cats have a severe case of fleas and cause major fela outbreaks in my yard that take several applications of having the yard sprayed. I am sure these poor babies (feral cats would feel much better if they were free of fleas and tapeworms. I can administer stuff in the food is the only way I can help them because they will not allow me to touch them or get close.
