Help, see the attached photo. These flying insects seem to have appeared after I just moved 20 yards of straight compost into my back yard. They are there all day swarming around not sure about at night. They appear to be mating. TThey have not gone away and now its been close to 2 weeks. Anyway to remove them or at least limit the amount of them!

Dear DaveLaf,
These are mating March Flies in the family Bibionidae, and probably in the genus Bibio that is represented on BugGuide. The male is the one with the larger head. We do not provide extermination advice.
