I tried SANMEX Fly and Wasp Killer having tried another brand and found it useless this year, although effective previous years.
Alack and alas SANMEX is no better - the flies are doing their own thing whilst I am doing myself an injury in my despair.
Not only are the flies resistant to fly sprays these days, they are also quick off the mark. So attempts to swat them have only produced broken utensils on the meal table. It really is not funny. Not only have we had to dib into our reserve funds we are having to pay out for the damage sustained. The pesky flies seem to know where we go when the lights go out because, sure enough everything is BUZZING in the bedroom.
It is really not pleasant having the little beasties crawling up you back when you are trying to 'wind-down' Someone said try Camomile Tea but that doesn't work either.
