How do I shut down the enemy jungler?

1. dont die to ganks 2)Get your own jungler fed by securing ganks for him, this puts a lot of pressure on the enemy jungler.
2. ward the enemy junglers camps. If you see him do it, and have pushed your lane, feel free to go nab him in the face, provided you have an escape route ready.

Pull pressure to yourself and be intelligent about it, Pink ward your lane as much as possible and use your actual wards deeping into the enemy jungle to give visionf or your whole team and not just you, if you are a mid laner warding the enemy raptor camp, so that it sees both the camp and the ramp down towards mid lane is the ideal spot wwhile having opposite side pxiel brush pink warded, top lane is a little bit harder, its probably best to just pink ward brush and maybe use your green wards for either tri, or like rift area, for bot lane support should keep around dragon warded, have a pink in the tris and adc should be warding the closer bushes or the lane brushes. Push in your lane if you see the jungler isnt around and when you know he is coming try to keep him there as long as possible, Never type "Go away" as it gives away your vision the best thing you can do is try to make sure he stays near your lane as much as possible while secretly being completely safe from their ganks.
