It's getting to that time of year when the number of house flies starts increasing rapidly.
Have tried a couple of robo can things and they are useless - I gather consumers institute came to the same conclusion.
Have tried some fly trap bottles outside - filled with horrible stuff. No difference.
Ideally we want something inside that will actually attract and kill flies quickly.
Electric zappers seem to be of questionable value (from what I have googled so far).
Anyone have some good tried and true that kills the little sods?
(I suspect I am asking the impossible to be honest - but always worth asking)
