Best method I was told. Build a 2x2 stone [or wood if low] foundation with 2 high walls, drop in with flyer, feed through wall. Has a massive hitbox to feed it through if lured close to a wall. No repel needed with this method.
Ragnarok: Get a dino that mantis don't become aggroed (i did with a wyvern), ghillie suit (not needed but it helps) and bug repellant, go to monster island (because its filled with bugs and you will not be easily aggroed by other dinos), give it a horn and mount the dino again and follow the mantis with him as nothing will target you. Easy tame!
