Around the 1920s, hand operated spray pumps atomised and dispensed chemical spray. The pumps were fitted with a small tank that could be refilled with liquid spray from bottles or tins. These uniquely shaped tin objects often advertised brand names such as ‘Fly-Tox’ and ‘Kix’.
Hand operated spray pumps became redundant after the introduction of aerosol fly spray cans in the 1950s.
The insecticide brand Mortein aired its first television commercial for aerosol fly spray featuring ‘Louie the Fly’ in 1957. Louie was an animated villainous character, and when paired with a jingle in 1962, he proudly sang of his own dirtiness – “Spreading disease with the greatest of ease.” Louie the Fly became a household name across Australia transcending many decades.
The introduction of effective chemical powders and sprays was groundbreaking and in 1948 a Nobel Prize was awarded for the high efficiency of DDT as a contact poison. DDT (Dichloro-diphenyl-trichloroethane) was a colourless, tasteless and almost odourless chemical compound developed as a synthetic insecticide and used in many homes across the world.
Although effective, it became apparent that DDT was dangerous to the environment, particularly wildlife, and was also a suspected carcinogen in humans, leading to its total ban in the USA in 1972, and Australia as late as 1987.
Fly killing innovations have come and gone. The battle against flies remains and is now part of our unique Australian culture, along with Aerogard, cork hats and the ‘Aussie Salute’.
