How do you counter twitch camouflage?

Hey guys,

Last game I played a match where the enemy team had a twitch.

I saw him running towards our group while we were going back to base, i saw him using camouflage so i used a control ward right in the middle of our group to be able to see him.

Next thing you know, he pops out of camouflage right next to the control ward and we couldnt see him before.

Putting control wards in plain sight just to counter twitch is already a pain in the a** to do, so if it even doesnt work what can you do about it?

TIA for help!
