Ive been battling these red wasps at my house...kinda a personal battle really the darn things are tough and keep coming back no matter what I do. Anywho I thought I finally got rid of the wasps but hornets moved in. Well I was walking around the yard and spotted them buzzing around so I went and got the spray. I walked up to the nest and sprayed them and instead of kinda flying off and giving in all hell broke loose and man these things were on the attack. I was running in circles and spraying so fast I was running into my own spray.... I think I hit myself in the head with the can. I thought Id let them settle down and move back in to spray some more....well they were not having it those darn things were aggressive as hell as soon as I walked up it was game on and I got what was coming to me I guess. Ive been stung plenty of times by scorpions, bees and wasps but this was a whole new level of hurt lol. I got dizzy and my chest was getting heavy the darn things packed a punch. I tried my hardest to play it cool in front of my family my back and arm were swollen like I owed those hornets money and lots of it. Lesson learned today.....get the spray that has some better trajectory.
