He may not look like a kitten anymore, but he is. He has reached his "teenage years"
, and you know what those are like. Full of the devil.
The water bottle and bitter spray is a good idea, picking him up by the scruff could hurt him, though, you could pull his shoulder muscles.
It sounds like he is bored and has a lot of energy to spend, so you have two choices that may help him "behave".
1. Play with him a lot to tire him out, or;
2. Get him a playmate that is about the same age as him to keep him occupied.
BTW male cats at this age are very social.
