Flies can be a problem around the chook yard and this Fly Trap has to be one of the most ingenious devices I’ve used in the garden. It has the hall marks of a true ‘garden contraption’ by being simple yet devilishly clever. Well done to Envirosafe for making these available to urban gardeners.
I first spied one years ago hanging off a cottage my sister lived in Yongala in northern South Australia, and was really impressed with the ingenuity, and its performance – these things capture a lot of flies – in fact so many that its staggering to see evidence of how may flies there are around you. I was really surprised to see one in our local Bunnings for just $9.95 more recently and immediately bought one. Ive noticed them in Stratco as well.
The fly catcher lures its prey from the smell from its bait initially, then eventually from the smell of the soup of drowned rotting flies. The flies negotiate through narrow holes into the container where they can fly (as flies do) but not escape due to the shape of the entrance-only holes, and their tendency to be attracted to light (phototaxis) How’s that for a token bit of science!
As soon as they stop flying, the flies slowly and inevitably drown in the pungent fluid in the jar to form even more of the disgusting bait. No batteries and self rebaiting – its almost the perfect fly catcher!
Fly Catcher maintenance once the initial bait is added – a yeast that apparently can be replaced by Vegemite and water – is not much other than the occasional water top up should it evaporate or as I found, the layers of captured flies was so great that newly captured flies could land on top of previous victims and so not be drowned.
A word of warning about emptying the contents. As mentioned, I added additional water as the level of fly bodies increased inside the fly catcher until it *completely filled up* with flies, so I had no choice but to empty it, but the smell is gag inducing Its utterly disgusting! I’m glad I dug a hole for the contents but I couldn’t cover it over soon enough to get rid of the stench.
I notice there’s also a European wasp bait for the fly catcher which would be a handy if you’ve got a problem with these nasties too.
All in all this fly trap is the definition of ingenuity, and definitely makes onto my list of Garden Contraptions.
Here’s the fly trap a week after re-charging its bait – already 1/3 full of dead fly soup!
