Did not do anything.

Nothing harmful, except for to the blood-suckers! Help tremendously! I have a reminder set to add one to the ornamental pond monthly. (Based on size / gallons, as to how much to use.). No harm to the "fancy goldfish" in the pond, no harm to birds, nor dogs who drink from pond. But - yes - prevents mosquito breeding. Our winters aren't cold enough, long enough, to rid us of mosquitoes. Yet other chemicals harm humans and other life. Yes, I'm a hypocrite. Love life, but ... mosquitoes? Grrrr. BTW, if there is anywhere that standing water can't be avoided, you can easily break off bits of these for those areas, too. They last! Work for at least a month, when used as directed. WELL worth this cost! Follow their instructions or ask. here, and someone will reply!

We have a small water feature in our garden, so for the second year I am adding one of these periodically. They certainly do seem to keep the mosquito population under control. My only quibble would be the claim that one lasts for “30 days or more.” They absorb water and presently begin to break apart. Perhaps the active ingredient remains in the water even after that? Don’t really know, so once the dunk is entirely reduced to just floating debris, I scoop that out and add another. That means the six-piece card doesn’t equal a six-month supply. Possibly this is just my misunderstanding, however.

Perfecto lo recomiendo para matar los mosquitos tigre . Lo uso en hidroponia . Los mata en un día , no queda ni una larva . La única pega que se deshace el corcho muy pronto

Perfecto para lo que toca. Lo utilice en un estanque de riego, donde había muchas larvas ya que el agua no se recambia demasiado. Ya no quedan larvas, el producto cumple las expectativas, una amarilla tiene un buen tamaño y alcanza para un mes. Muy contento con la compra.
