Is it normal to have a swarm of dying flying ants in your house?
Few days ago, I noticed a swarm of flying ants inside the house, there were tens of them. They were all dying, spinning, and acting really weird. It was pretty creepy so I left them alone. I came back later and they were all dead.
My first reaction was that someone sprayed pesticide in ant colony and they were fleeing, but everyone denied it.
What on earth is that? Is it normal?
