I'm staying at a friend's apartment in the Northern part of the Dominican Republic. I've noticed an infestation of ant-like insects in the apartment. Here is a description of their appearance and behavior:
-they gravitate towards any food that is left in the open. Takes them only a couple of dozen minutes to swarm over any unattended food. Even after I remove a food source, they are crawling back and forth to the area where that food used to be.
-they appear very coordinated, and form a line from their origin to a food source, and back.
-their origin appears to be a loose wooden panel on the floor.
-they are reddish-orange, appear to have wings extending from the second half of the torso (hard to tell, since they are so small), are very narrow, and are about a millimeter in length.
