Maybe I could look into using liquid Bti. Might be cheaper in the long run.
I found that using Mosquito Bits is far more economical because I use less. Although they say it doesn't last as long aa the Dunks. You might look for it when the Dunks run out.

I love this stuff. I use it in birdbaths, rain barrels, pet water bowls, planter drip trays. I can sit out on the patio (in the woods) after dark with no mosquitoes biting. Even after the visit from Harvey.
