Those sparrows are worth the barn space. Doubt I could use the Spartan, tho I use the dunks, and bits on smaller waters. Also use a Repel so I can walk outdoors at all. The hummers and rainfrogs all eat the skeeters, but I like my porch to drink a cup and rest a bit. I see flying hordes of skeeters just at the Repel boundary, so I know they aren't too far gone for the hummers and frogs. It may be that some areas could use the boron, but I think in my humidity the stuff would be mold in a day or two, so dunks for me.
