Poor Little Ant

Frequently find a little black ant crawling on my computer or arm. Blow or brush it away. The black ones don't bite and don't see red ones much, but don't want them crawling on me or laptop. As they fly off  from where they were blown or brushed, I wonder if they will find their way back home. And what if it's far from home. I checked on that and found that sometimes they can be accepted in another ant community. Ah - there's one now on my knee. Good luck little fellow!
