Anyone use basil as a pest deterrent?

lol I have a basil plant in my outdoor garden, and I saw an aphid on one of its leaves. I also have mint, which is supposed to be another pest deterrent, but I still have a few gnats hanging around.

I'm probably about five weeks till harvest for my auto white widow that's out there so hopefully they don't BUG me too much.

 

Ive heard of them using that and mint for outdoor grows especially

 

Seems like my basil plant outside has the most pest damage. Obviously it doesnt deter much
