How to clear the jungle of vicious animals that eat their own kind?
Poison their water. Deny them their food. Deny them the ability to act as a pack in hunting. Clear cut and monitor their sanctuaries. Deny them the time to plan counter attacks on enemies. Get them on the run and keep them on the run. Pick them off one by one when the pack disintegrates.
