Contains:  Pyrethrins 0.38% w/w
Control: Flying and crawling insects
Application: Compression sprays / mist / fog

Pythrin 33 is a ready-for-use non-persistent insecticidal spray for fogging, misting or surface treatment in food handling premises and for public hygiene / nuisance insect control.

Pythrin 33 is synergised with piperonyl butoxide (PBO), increasing efficacy and inhibiting the insects natural resistance mechanism.

Pyrethrins are natural substance purified from chrysanthemum flowers. Chrysanthemum flowers have been available in Europe for over 150 years and in their powdered form were used as louse and flea powders. It is only in the last 50 years that liquid concentrates for public health pest control have appeared.

Pyrethrins cause rapid knockdown of insects followed shortly by death. The mode of action is non-systemic and contact action caused by the binding of pyrethrins to sodium channels inhibits

the insect’s nervous system. This mode of action leads to a broad-spectrum of insecticidal activity, and due to the non-persistence of the active ingredient in the environment, insect resistance is very rare.
