confirm that ‘with the repeated use of the same insecticides, flies develop resistance through genetic mutations that make these products less effective’. To be clear about this, I inflicted a popular brand of French fly-spray on my invaders….and it had zero, zilch, no effect on the recipients.

Hitchcock sought a suitably terrifying follow-up to The Birds, but never found it. Were the old sex-beast alive today, one can’t help thinking that he might have gone for The Flies. You may think I jest, but these persistent little buggers are cavorting all over my kitchen surfaces, tables, plates and skin: and I feel powerless to stop them.
