“Probably an exodus from the hurricane,” one person said.
Garrett O’Dwyer told CBS3, “They swarm into your hair, shoes, and shorts. Safe to say the bugs are firmly in charge.”
One woman said she had to use a fork to fish the bugs out of her wine, while another said she’d find the tiny insects in her food as she ate outside.
“People are running all over Old City and fleeing seeking shelter,” another said.

“Hmm. No, We don’t know where all of these gnats came from, either. However, we, for one, welcome our new insect overlords,” said Philadelphia police in a Tweet.

“What people were talking about, that was swarming were these ants,” said Isa Betancourt, who researches regional insects for the Academy of Natural Sciences of Philadelphia.
“It’s just kind of this great big event that happens across the colonies and this is how new ant colonies are made,” she says.

“The reproductive ants the males and females rise up from the nests and it’s their kind of maiden voyage they fly around, find a mate and then right after they mate the female kind of clips off their wings and go find a place to start a nest,” said Betancourt.MORE NEWS: 18-Year-Old Student Shoots Himself In Leg At Gymnasium In Philadelphia Learning Academy, Police Say
They say this can happen every few months. It happened earlier this summer but people didn’t seem to notice as much.
