I’m all for being humane but I would stab a bed bug with a pin and yell “die, fucker”. Same goes for mosquitos, ticks and fleas.
Isn’t diotemacious earth cancer causing if you breath it in?
Most shit will cause lung cancer if you make it into a powder and inhale enough of it.
In this case it’s pretty much the same risk as inhaling asbestos dust. Fun fact, in the past, beer was filtered through asbestos, which was perfectly safe because asbestos is only dangerous when inhaled. Nowadays it’s filtered through Kieselgur because its properties are pretty much identical to those of asbestos.
Pretty sure that if you got snow in your lungs you would get pneumonia, or perhaps frostbite in your lungs. if you get frost bite in your lungs repeatedly, just as any other repeated injury it can increase your risk of cancer in those cells that are repeatedly damaged.
