I tend to hang my packs of desirables from branches off the ground, this also keeps it dry under the canopy. This works well in boar country. We have plenty of raccoon and fox, but they haven't been brave enough to dismount my pack, so far.
In Alaska, when I was young, we would go on extended hikes in bear country. Here, scent reigns. Wrapping your foods well and tight was a ritual when camping. As well as being mindful of not leaving remnants or dumping excess. I live by the same rule today, although I tend to get lazy when I know the area is limited in species.
As for bugs when out in the open, there are a variety of scented species; Eucalyptus, CA.Bay Laurel, Sage species, etc. that I utilize for placing among the bedding material to act as natural repellants. For me here, CA. Bay Laurel is the big one.
I also will pile up some of the scented leaves and occasionally throw a bit in the fire to act as a smudge throughout the evening if bug presence is high.
I've used this technique to fend off red ants (try urinating while almost tap-dancing in the dark!) that surprised me one dry Spring in the Ventana Wilderness.
Smudging is one of the oldest methods for natural insect repellant in your camp shelter and bedding.
Keeping a tiny pouch filled with odiferous herbs or oils can provide varied uses: repellant, cooking, tea, as well as smoke mix.
An excellent natural repellant is Rose Geranium oil (mixed with some other oil for skin application otherwise can irritate the skin) for ticks.
I have also utilized clay wiped around my calves when I was being ravaged by sand fleas along the coast in Central America....
A while back, when I hiked the Highlands of Scotland, I was severely bitten all over by 'midges' or no-see-ums, as well as horseflies, they call 'clegs'.
Plenty of sheep and sheep scat in the Highlands means plenty of horseflies. The locals swore by Skin-so-Soft moisturizer, but it did nothing for me. Deet or equivalents did nothing as I was hiking on average 12 mi. a day, sweating. I did not want to keep rubbing myself with all those chemicals if they did nothing for me.
Literally hundreds of bites later and days into my long trek after listening to local suggestions (as I usually like to try what works for the locals, but in this case, they were adapted to the bites and had no reaction to them), I resorted to Tee Tree Oil which I almost always carry a little vial of for its multitude of uses when I travel. But I had to ration it as I only had so much. This proved useful, as there was almost no plant diversity (planted rows of Pine, except for the wonderful shrubs growing on mountain faces at high altitudes) there for me to utilize, meaning little animal diversity: the occasional bird, sheep and insects.
Horseflies were unconcerned as they have a unique way of feeding, but I noticed a reduction in the number of midge bites.
Apart from Guatemala/Belize (two words: scrotum bite!) it was among my most severe cases, mostly due to exposure time.
Insects can break you down, mentally and physically, and are enough reason to learn local sources of repellants as well...
The key to remember is: there is no single cure-all. A variety of methods will prove the most useful, bedding smudge, fire smudge and natural oils or coatings on skin combined will be of more use if the scenario is severe enough than just one lotion...
Another thing to consider, is camp situation. Are you high and dry, or low and wet? I always consider this as my first step in insect reduction, esp. with mosquitoes. Stagnant air or pools and water are to be watched. I see many campers setting up right next to water sources and complain about cold air and bugs.
