I found one Yellow Jacket nest.
I was out at 8:30 AM but there was no action.
I went out again an hour later. I was standing about 30 feet west of where I had been stung.
I heard bees whizzing around me but did not see any where I expected them.
I moved my perspective a little bit and the hole was six feet from where I had been standing.
Maybe there are two nests!
This one was pretty busy with a landing or departure every ten seconds.
I hosed it with the better part of a can of commercial spray. Going back several hours later it didn't seem to have any effect.
I don't see any point in looking for the second one until after I deal with this one.
I slacked off after I started harvesting hazelnuts. Getting a good picking was my sole motivation.
I was catching mice and the odd chipmunk but no red squirrels.
I think I need to get the trap up in the trees to catch them. William Reid in Kansas has a system.
The 5 gallon bucket that is 3/4 filled with water and topped with sunflower seeds has been the bees-knees for catching chipmunks. Many thanks to whichever reader suggested it in comments.
