Question:
I live in proximity to a 20' x 20' x 2" to 4" pool of standing water on tar
that I can not remove, but I could treat if I am fairly discreet about it.
I want to prevent it from becoming a mosquito factory.
What's a good, non-toxic treatment that would serve this purpose, but not
harm any birds that might find it attractive?
Answer:
-A few 15-cent goldfish will take care of the mosquito larva. Rosy
red minnows will clear up the larva too. Dunks work too, although
these are a bit more expensive. I guess if you added fish, someone
will know they were added by someone, but so what?
- You could try mosquito "dunks", doughnut shaped discs containing a
variety of Bt that kills the larvae but is not toxic to birds or mammals. A
good garden center would stock them, or you can do a search and order
online.
-How is this possible? Is it a shaded section of parking lot with one
helluva sinkhole? Many cities around here have regulations against standing
water [West Nile virus has put a scare into them] - maybe yours does too?
There are mosquito treatments for standing water - ask at your local
nursery.
