Well, my Ex got stung by a hornet too, that was attracted by a head lamp and did crouch into my canoe and into her sleeping bag. Here on my brother's farm we have some hornets that indeed come into my construction trailer if I have switched on a light and afterwards do the usual silly things until I throw them out and close the window.
The gas cardridge risk is worth an own thread in my opinion. I opened it here:
What do you all know about camping gas cartridges that exploded? Which? In combination with which stoves? In which circumstances? Why? How? Was the reason a user fault or a construction fault or what was the reason? Tell us what you know about that!

If you want to lighten the load radically and if we are talking about short outings alcohol stoves are the lightest option so far I understood, if you don't need exactly the amount of energy that can be bought in one of the gas cardridge sizes, what's rather a week than a day. Ultralight trekking experts made a science out of the question. But I use gas cartridges also where no other stoves are allowed, like at some camping sites in south France, and you decided to avoid gas cartridges, so the question when the use of gas stoves becomes lighter than alcohol stoves doesn't matter here.
Because I use either a wood fire or a screw gas cartridge I can't tell you from own experience about alcohol stoves. But other members can and will inform you if you ask about it in a seperate thread, what's worth it, because there are countless different options, some more practical, some cheaper, some lighter than others. It's some kind of own science and would derail the thread here if we try to discuss it in this thread.
That's why I suggest that you ask about that in a seperate thread.
Some alcohol stoves can be made easily and very cheap at home or even on tour.
The other options cost a bit but usually far less than other stoves that use different fuels. And apart from wood that you find in the forest spiritus is the cheapest fuel that you can burn, so far I am informed.
So, if you want to save money for fuel and lighten your load it's highly recommended to inform yourself about alcohol stoves.
