Question
INSECT01
INSECT01  
APPEARED TONIGHT IN OUR SLIGHTLY DAMP, BUT USUALLY INSECT-FREE BASEMENT. ATTRACTED TO A VERILUX "HAPPY LIGHT". EVERY FEW MINUTES ANOTHER APPEARED.  ONE OR TWO SEEMED TO FALL FROM THE RAFTERS, WHICH, WHEN SWEPT, REVEALED NO NEST. ONE HAS A REMARKABLE ABDOMEN. I'M WONDERING .. QUEEN?

A PICTURE IS INCLUDED. THEY ARE ABOUT 8 MM FROM HEAD TO TAIL.
THE BODY IS QUITE HARD.

FOUND 7/5/16 IN DREXEL HILL, PA 19026 U.S.A.  
THE WEATHER HAS JUST TURNED HOT AND HUMID OVER THE LAST FEW DAYS.

I WOULD BE EVER SO GRATEFUL IF YOU COULD IDENTIFY THEM.

THANK YOU.

Answer
Dale,

These are winged ants. I'm not certain about species but given the size they probably are not carpenter ants. In this situation odorous house ants are very common. All of the nuisance house ants should br controlled with baits rather than sprays (see http://www.livingwithbugs.com/ant_bait.html). Place baits where you see ant trails inside the house.
