 And so like if you had like a little, you know, a little waterfall and little pond or bird feeder, you know, kids swimming pool or something where you wanted to have water in there, but you didn't want mosquito larvae in there, you would just use these mosquito dunks. And I think they last for about 30 days. I've used them before. I have a couple of containers that I use for catching water all the time. Sure. And I use that for my plants outside.
