it would be a double handed tool which made with tree bough and itsy bitsy's web.
it would be considered like a sack. and you can put all sort of insects, even midge too.
since there's no way to avoid midge bite except running away, i'd like to suggest this tool.
but only empty butterfly net would be used as a bug killer.
and other idea:

many insects are tend to gather to the light of flame. so we can use a lantern to collecting insects especially at night.
but in many case dumb insects throw themselves into the flame. if you want to collect insects, you'd better pick them up asap.
