Query: Marvellous Mosquito Bits

This product works brilliantly! I threw about 10 of the little bits into a planter full of water that I use as a mini pond and the larvae was dead in no time and the resident frog was totally unaffected.My only wish is that we could buy these Mosquito Bits through Amazon UK or France as my total cost was almost $57, for a $14.99 product. That little gripe aside, I would most definitely buy these bits again, without hesitation.
