    Try this out for math.

    How many pounds of active-ingrediant Fipronil is in a 50 bag of Top Choice?

    The reason is that I am trying to educate people about how much chemical is on their yard compared to what the vet gives out when he gives them Front Line for their dog or cat.

    I have already tried to look for it on the lable and I can't find it.

    I will try.
    In a hundred pound bag at .0143 percent, you would have .0143 pound.

    In a 50 pound bag, you would have half that, or .00715 pound.

    That is around a tenth of an ounce.

    I would say about a half teaspoon.

    The label I see is 00.0143%...

    That would mean 50lbs x 16 oz/lb = 800 oz

    800 oz X .000143 = .1143 oz... just over a tenth of an ounce in a 50lb bag.

    Ah Riggle, beat me by a minute.

    Think about this... if the fipronil were it's own prill, instead of spread onto all in the bag, about 1.5 out of every 10,000 prills in the bag would be AI.
