We have a terrible problem with flies at the moment but I managed to grab one and photograph it. Does anyone know what kind of fly it is so that I can kind better methods for getting rid of them? It's really small, probably 3-4mm in length. And they move pretty quickly. I put up a fruit fly trap to no avail. They also aren't attracted to honey or sugar traps. They just come into the lounge and continuously fly or hover in circles until it gets cooler outside when they leave. Any ideas? I'm pretty sure that they aren't fruit flies, and also pretty sure they aren't drain flies as they don't show any interest in the kitchen sinks and other stuff similar. The location where my house is built used to be a landfill site if that helps.
