@jeffkane4391 bummer! Last year, there were almost none where I live. I am happy to see some of both this year. Not as many as I wish, but some is better none. I haven't looked up any data about how bats fared with white nose this past Winter. Had you heard?
I put dark colored guppies in my pond this week, maybe they'll survive the summer and eat the mosquitos. I hope your rainbowfish project of breeding rainbowfish goes really well and creates more rainbowfish for you.
Putting the barrels in the ground does help stabilize the temperatures quite a bit. We still get into the 50s at night and occasionally flirt with the 90s.
We are surrounded by swamps and bogs here. We definitely produce a healthy mosquito population with all the standing water we have. Fortunately, my old neighbor moved, he used to spray his full property...
