I'm certain I have not replied to all those offering support, suggestions, or free hatching eggs. I did not mean to ignore anyone, I just lost track of those not sent by PM, and have been very busy. So, thank you everyone. I've enough eggs of my own, added to those I may have coming from others, to restock. God willing, by late fall I may have a breeding population going again.
Two applications of Mosquito Barrier left a reduced number of buffalo gnats, but enough to still be a problem. I called the local distributor, who, it turns out, had already contacted the manufacturer in regards to my problem. Canadians have discovered that in heavy blackfly hatches, Mosquito Barrier has to be mixed at 12 oz to the gallon of water instead of 3 oz, with 2 tspns of Palmolive dish soap per gal added also. Canola oil, usually added 1:1 to Mosquito Barrier, isn't necessary for buffalo gnats; but does aid mosquito control by floating on the surface of still waters as a very thin film, and kills the larvae as they hatch.
