These buggers are the most dangerous thin you can ever encounter in normal areas and yes the spawn just about everywhere the will slow u or your tame down so you can not I repet can not escape so if there is a pack do not Bing a medium mount anywhere nearby them if on foot it is easy to escape you can usaly run away to water, off cliff (parachute or wing suit), or runing past a small or medium wild animal (distraction) and a second choice is to kill by youself too by using Vilas on both ravagers but if more I would not recommend
