Yellow Jackets and Wasps
Late summer's uninvited guests at outdoor dining, trash corrals and anywhere sugar sits out.
Where they thrive
Ground holes, wall voids, eaves, under decks and stoops. Drawn to soda, fruit, meat and open trash.
How they behave
Can sting again and again. A crushed yellow jacket releases an alarm scent that calls the rest of the nest.
In New York City
Worst from August to October, when colonies peak and swarm outdoor dining, cafes and dumpsters.
Did you know?
The bald-faced hornet is not a true hornet. It is a black and white yellow jacket.
