Durban in the summer is hot, humid and wet – the perfect weather for a plague of flies. Which is why each year I buy one of these nifty fly-traps and hang it in a tree. The trap is an ingenious design, with a funneled entrance which makes it easy for the fly to enter but near impossible to exit. The liquid at the bottom consists of a strong-smelling, protein mix that works to attract the flies.
In the permaculture course I recently attended, they showed us how to create a similar trap from an old two-litre Coke bottle so next summer I’ll give that a try.
