Gold at the Bottom Of A Smoking Tar Pit (stop bug bites naturally, day and night)

The mosquito is more tenacious and will require a thick layer, but no-seeums and other small biting bugs can be stopped with grease on your skin - any (natural) grease or oil you are ok with absorbing through you skin.

In the sun, the bugs typically wont bother you but in the shade or later in the day, smoked hide for the legs and torso and a heavy grease on your face and hands will reopen the outdoors without the need for harmful bug sprays.

If you dont have grease, do as the Arab women do and cover your face and forehead with a rag or shemagh scaf that is loose. Fold corner to corner so the scarf becomes a triangle and fold over the long upper part (of the upside down triangle) again to achieve close to four layers of cloth, necessary for the forehead. Put the left side on your forehead and wrap the remaining 2/3rds around the back of your head and over your mouth. Tie  the ends together and adjust to cover your mouth and as much of the forehead and corner of the eyes as possible. Its difficult to cover your head using said tie so you'll likely use this tie with a hoodie or second scarf. Woven fabrics only stops m

To keep bugs off your face during the night and you are a back sleeper, use the same shemagh scarf, and tie two of the same side corners together to make a small cape. You will need additional covering for your head cap and forehead and will also need to have an elivated head while you sleep. The shemagh cape hole will be too small to fit over your head, so it should sit snug on top of the cap. Drape the cape material over your face and chest. As is, this will be too stuffy to comfortably sleep, and bugs may still poke through the cape and bite your nose or cheeks, so find a stick with some broken branch protruding from the side and make a small tent on your face, neck and upper chest area with it and the long cape material. Be carful as the shemagh is typically made of a light weav delicate material and will easly tear if the branch gets caught in it.

If you don't have a shemagh, or you find it too stuffy, look for a loose weave or raggedy wool sweater with holes small enough to stay mosquitoes.

For the feet - moccasins. I am strongly inclined to believe that the moccasin was not warn at every moment, but more like slippers during sleep and walking where and when foot wear would be logically necessary.

Yet another approach, though immobile is a small smoulder smudge smoke. The smudge can be any material that creates a smoke - even dry wood on a hot bed of coals.

If you have made an evening fire, simply throw some thick stick chunks, leaf litter, anything on the coals to let it just sit there and smoke as long as you need; sometimes the bugs stop at sun fall and this smoulder is enough until then.

The smoulder wont distract all mosquitoes, but it will, soon after lit, about 90% of them.

 A somewhat "self feeder" smoker.

I suspect that said approach is the origin of the "smudge" for spiritual cleansing practice where dried herbs such as sage are smouldered and wafted. Perhaps it was common to use where a fire was not present, to "clear the air" of bugs and bad spirits in a small tent structure for example.

Sweet gras has been found to deter mosquitoes as well as DEET.

Use respect when harvesting these herbs. I have spread wood ash in the harvest areas in the past to help the plant regenerate.

An idea to try may be a necklace that holds braided smoking material; I saw that in a movie based on true events once.

Mud does prevent mosquitoes from biting; but, there are other biting bugs which are likely in the same location, which are not deterred by the wet mud. Muds can also dry quickly and when dried, will rub off. So you must be aware of which mud you choose. I have used black mud which will easily rub away when dry; a grey fine clay I found to cling better but more exprimentation is required. 

I feel grease and good clothing has most often, traditionally, been the go too approach.
