OK you are having a festive get together with family & friends on a beautiful sunny day. Everyone is having a great time. You fire up the barbeque and the smoke wafts up 10FT and ticks off the hornet nest above your head. They are now buzzing & looking to attack anyone in close proximity to their nest. Because they are annoyed they release a pheromone that tells other hornets to be equally annoyed and attack anyone nearby. If you are stupid you will risk people’s life (anaphylactic shock) and use some store bought “wasp jet freeze” which will stain your house & really tick off the hornets. Or you can be wicked smart and call EHS as we are the experts at protecting your family & home!
