Toby,

We built a house with a back porch 18 ft. from the edge of a 2.5 acrec pond. I have 40 acres with two wet weather creeks (one goes through my pond). I use the mosquito killing bacteria and do not have any mosquito problems. I apply to all standing water in Mid April (Northern Okla).

Whatever I have left over after treating the creeks, I use in the shallow area of my pond. I buy 2 two pound containers. (I am guessing here). I get mine from Lowes. I wish I had the proper name but I don't. It comes in a clear square bottle, the material is straw colored and is in granuals. Great stuff. Mosqueto larvea eat the bacteria and die.

I read that mosquitos generally remain within 100 yds of where they are born... Of course, we have wimpy Yankee type mosquitos here in North Oklahoma.

Might be cheaper and easier than a magnet. I also put up a bat house on one creek.
