I noticed mention of this in the water feature articles. On the web I cannot find a decent review of it. Does anyone have experience of the efficacy of floating mosquito control rings?

Sorry, Glen, but I've never tried them. I just use fish.

Hopefully, someone else will be along soon to share their knowledge.

Thanks Chelle. I have just got some good answers over in the water garden/ ponds threads.

I was under the impression that they worked quite well. Could you please post some of the information here?

Not sure how to do this Wolfie.

I use Mosquito Dunks in all my standing water around the yard, Glen, but not in my pond. The goldfish take care of any mosquito larvae in the pond. So plant pots, puddles, ditches, spots in the rain gutters where the water sits, they all get a little chunk of Dunk about once a month.

The main active ingredient in the Dunks is bacillus Thuringensis subspecies israelensis which is a naturally occurring bacterium that is toxic to the mosquito larvae, but doesn't harm fish or animals. Our cat regularly drinks from the plant saucers and has done for years. She's 13 now, and in pretty good health.

The package does caution you not to use them in water intended for human consumption, but that's just 'covering their you know whats'.

Glen - I usually buy mine online through ebay:

They are much cheaper through a bulk purchase. I buy the cheapest brand as they all seem to work the same.

Each dunk lasts about a month. So not too bad if you don't have too many water gardens.

Thanks, Glen! There is a way to link to a specific post, but actually, just copying what folks posted is a bit easier, since that way you don't have to click on links.

I just found this thread. Glen, I used these & had great success with them! They are great, easy to use & they work. When I had very small places like saucers under plants that got standing water when it rained gobs but the plant was too heavy for me to lift & dump the saucer; I would break off appropriately sized pieces & throw them in the saucer.
So far, I haven't needed them since we moved but I was sure thankful for them when I lived in zone 10 Florida.

Also, pets should not drink from water containing these (from the package label) so you don't want your kitties drinking but I believe your kitties are strictly indoor cats right?

Thanks Ann. The kitties are indoor only - though the menaces would like it otherwise.
