THEY, being the yellow jackets, really have it out for us. Our lawn man found 3 more nests near our house in the ground. He killed all of the nests but there is one in the railroad ties that the landscaper used around our house. This time, one of the nasty creatures, stung my Nikolai. He was stoic of course and said it didn't hurt very much. I treated him with vinegar and he seems to be fine. I know that he does not have the reaction that Deniska does. I will be glad when winter comes and the yellow jackets die.
