Once netting or clothing is impregnated there is no vapour action and they are safe to use. It is not an insect repellent for use on the skin.

    I followed the instructions which were easy to follow. I've not had a chance to try how effective it is yet

    needs more instructions for application rates

    Bought this to spray a fabric upholstered chaise which for some reason the mozzies love to hide behind - it is pushed up against the wall and when you sit down a cloud of skeeters would rise up from their hiding place to attack and it was awful.
    Instructions on the pack for dilution rates vary wildly with no explanation as to why, or about how to adapt to scenarios other than treating cotton sheets , t-shirts and moz nets by soaking. Had to research similar products and do some maths about concentration rates to get a sense of what might be safe yet effective for my situation.

    In the end still wasn't sure so I used the t-shirt concentration - figured it was safe enough to wear against skin at that rate so should be ok to sit on. I put it in a spray bottle and sprayed until the fabric surface was damp but not to to the point of runoff. Smelled bad wet but dried fast on hot day with good ventilation and no smell once dry.

    I can't recommend anyone else try this only because it's 'off-label' usage, but I will tell you it has worked and no one in the house appears to have been affected by it except the mozzies. We have no kids or pets but I still prefer not to use any kinds of pesticides if I can avoid it. I figured since the label said you could dispose of leftovers in a non-food producing part of the garden it probably wasn't the most toxic product in the world. You can read up online about its persistence in the soil - it lasts longer in moist shady areas, so maybe pick somewhere sunny. Whatever you do, follow all the safety instructions and dispose of accordingly.
