Thread: fly spray

An old trick from some canary breeders I knew, was to plant Marigolds, around the aviaries in which they kept their prize birds. The reason was that Marigolds, apparently are full of Pyrethrin a naturally occurring insecticide.

vis : Pyrethroids are synthetic insecticides based on natural pyrethrum (pyrethrins); one common example is permethrin. A common formulation of pyrethrin is in preparations containing the synthetic chemical piperonyl butoxide: this has the effect of enhancing the toxicity to insects and speeding the effects when compared with pyrethrins used alone. These formulations are known as synergized pyrethrins.

It is my understanding that the ingredients in Fly Spray are related to or derived from Pyrethroids. One I'm looking at right now has - Tetramethrin, Phenothrin and Allethrin.

As one who sprays Fly Spray directly onto my skin and clothes, when confronted with any number of Mozzies or Sandflies, I am not worried about food, that may get a bit of spray on it.


No doubt someone with a better Chemistry education, will be able to give a more definitive opinion on this.
