Moth-Be-Gone

Supposedly, there are many ways how to prevent being violently eaten by Giant Moths although their efficiency is highly dubious if they do not include the step of: stay the heck away from the mist regions. If avoiding their habitat is not a thing that you can do, think again, if you truly do not wanna get eaten. You can find an amulet, a spell, a map of a safe route and many other things that should help you survive in the mists, but if they fail you, you wouldn't exactly be in a form to raise a complaint. Do not fall for scams and cheap trinkets, their price might be too high in the end and your fortune and dignity might not be the only things that you'd lose to them.
If you trully do need to go through the mist and survive, it is worthwhile to invest into a good mistwalker that will guide you or a small group of people safely to a certain destination. The more unusual or distant place you wanna reach, the bigger the price. Their ways of not attracting the moth's attention are considered to be the most reliable, as the fact the mistwalkers are still breathing and moving is a good enough of an evidence.
The most common and financially efficient ways are the Moth-Be-Gone herb pouches. These fabric pouches filled with smelly herbs get tied around one's waist or neck while traveling through the mist to repell bugs and other monsters. Their biggest disadvantage is that they need to be made over time and usually last for one trip only, depending how far you go. It's best when the entire expedition makes them together, so the herb smell can also seep into their regular clothes and everyone knows the ingredients that go into the pouch. Different regions have their different dangers and require a slightly different recipe. A bought pouch will never be as efficient as the one you make directly before your trip under the guidance of the leader of said expedition.
And lastly, it's good to say a little prayer before you put it on. Every mistwalker has one of their own.
