Well, the insecticide comes in a "poofer". The DE...they have to keep trudging through it and get a lot on them..works well for worms and insects on the ground...Their shells or segments get full of it then they die. But IDK how it works for a hanging nest and how much gets back to the hive to kill the hive and queen. If you kill 75% of a hornet's nest, you don't kill the nest and they just "come back".
I got some insecticide so it will poison the nest. Like I said, don't like it with all these honey-bee problems these days. But I hope the bees will not go inside the heater. The wall one...will be plugged up after the nest dies. Best I can do.
