I thought I would throw a little more insight on working with living subjects for macro photography. This technique is not a new one and possibly a lot discussed over the internet.
Golden Tip: Freeze the action, but don't kill 'em.
The best way to slow down a living subject for macro photoshoot is to freeze them. You can captivate your subject in a small jar and put in your refrigerator to slow down the subject. Try with 1 minute inside the fridge and if the action is still higher, try for 2 mins. This is good enough to slow down your subject for the next 3 - 4 minutes, but ensures that your subject will walk away on its own once your photoshoot ends.
You can repeat the above procedure to do more number of shoots. But wait till your subject gets back its complete action before you repeat your task.
