Hi, I didn't know whether or not this was in the right subforum but it's technically biology. Spoiler: Context Basically my room window is a few meters away from a tree that has some bees, wasps and hornets in it. At night, they sometimes wander into my room since I do not turn off my lights and I usually leave the window open for fresh air. I did buy one of those window nets that should prevent anything from going in but it is not really sticking well to the window and it has gaps in it. Night before that I had a hornet in my room and it was a pain to get it out, so I remembered a trick that my father had shown me some time ago. Basically, using a parfume (which are all flammable), and a lighter to produce a small flamethrower. It would most definitely aggravate bees, wasps and hornets but would it incapacitate them, burn their wings, kill them immedieately or would they just get angry and attempt to sting me? Thank you.
