Oh, the winged ones are when they swarm in the Spring. We had those in the basement of our old house a couple years until we'd lived there long enough I guess to change the patterns of how the house was used. These are just little black guys, the tiny ones that aren't too noisome as long as they don't wander into my storage cabinet. I have liquid sugar bait that makes them go away for a month or so at a time when that happens but an entomologist said we'd need an exterminator to exterminate into the ground. That sounds a bit more expensive than I care to mess with at the moment.
