Here's why flying ants were taking over Metro Detroit in swarms

DETROIT – Swarms of flying ants were buzzing around Metro Detroit on Wednesday, raising curiosity on social media.

They swarmed many communities, covered cars and landed on people.

The ants show up at the end of the summer to breed and form a new colony. The insects reproduce mid-air in what is called a nuptial flight. 

Once the ants perform their reproduction flight, the males die and the females fly away to form a new colony.

The phenomenon is usually a one-day occurrence, though it depends on weather conditions. It's likely the ants won't be seen again until next summer.

If you see flying ants in your home, you should check to make sure you don't have a colony inside the house.
