At 3:00 this morning I woke up feeling wheezy, took a puff of my inhaler and felt something hit the back of my throat. After several minutes of spluttering, I discovered the source of the problem was an earwig that had crawled inside the case and settled in the mouthpiece. The cap was on, so it must have got in the small gap between the case and canister. This was quite unpleasant but came as no surprise, as the same thing happened to me just a couple of weeks ago.
We seem to be overrun with earwigs at the moment and they're especially keen on hanging around in my inhalers (which I'll be keeping in a tin from now on). Has anyone else experienced this? I've had asthma since childhood and until recently it had never happened to me.
