The product is a strong desiccant that dries out the waxy oily surface of insects causing dehydration that eventually results in death to the insect. Microsurgery of affected insects also demonstrates that Zone Defense solidifies in the hind gut of insects causing blockage that result in eventual starvation. In humans the product is completely passed through the urinary system in approximately 90 hours. Zone Defense has been university proven to be a highly effective residual insecticide.


Zone Defense is stable and does not change under normal storage conditions. Wide fluctuations in temperature and humidity can result in caking. Care should therefore be taken to avoid such fluctuations during storage of the product.
