I have a Rockwall near our garage by our house and we have a species of huge hornet basically excavating the dirt out from the rocks . These are not the little yellow jackets. These are 1 1/2”
2” sized …..These are big bastards….. they are leaving dirt piles all in front of the wall. I went to Walmart and picked up a can of wasp / yellow jacket spray -that shoots out about 25 feet -I have absolutely doused these giant hornets with the spray. It doesn’t stop them at all. They just keep flying around and it literally has no effect on them. Is there some thing that is more commercial grade that someone can recommend? Getting stung by one of these close to 2 inch size hornets is going to hurt like hell.
