Hi Chris,

I keep a fishless pond for amphibians and insect larvae.

I keep mosquitoes out of it by using granular Mosquito Dunks.
I use the granular kind because the 'Frog Bog' is stuffed with
plants and there are lots of nooks and crannies so I broadcast
it to get in all those places.

Don't mosquito dunks kill _all_ insect larvae?
