In my house we're starting to get some very small flies flying around the house. We had this problem before but we sprayed some plants of ours and it stopped but we tried that this time and it doesnt seem to be working. Doesn't anyone know of a solution? They're very very small bugs. I'd say 1-2mm. You can kill it with your hands and not even feel a thing because they're so tiny. But it's just plain annoying.
