i've done lots of various things thru the years to try to naturally regulate my enviroment. Something i think is good for woods folks to have, for things from fleas (can be quite a problem at times), ticks, mites, spiders and such is:

alchohol and a hand pump sprayer-

oil of Erigeron (flea bane) a type of wild aster
borneol camphor (very inexpensive from a chinese herb pharmacy)
Bay leaf oil
Pennyroyal oil
clove oil

you can spray anywhere - on the floor, around the door, on the dog, on the cat (if you use erigeron, then make sure that preparation be used along the neck line and spine, so they can't reach it to lick it. You can spray your bed down, and squirt it into nooks and crannies where little biters may like to stay.

for the inwall chipmunk discouragement (again, i think its better to 'discourage' rather than to kill), i would reccomend an aromatic liquid, of alcohol, borneol camphor, cinnamon and clove oil. if you have access, spray that allover inside the wall, or, drill some strategic holes and squirt copious amounts in. buy a couple pounds of cayanne pepper. if there is half an inch of it where they walk, they will soon decide to find a more convenient place to walk too. or, open a bit of the wall, put in a live trap (they just cannot resist peanut butter), and remove them one at a time, and take them to a wonderful abundant wooded area a bit removed from yourself, then pepper the walls and close it back up.

some ground insects that can be a problem, can be eliminated or discouraged with diatomaceous earth, and this also works semi good with wild felines as well, don't like the gritty feel between their toes.

deer generally think the highest pole in a fence line is the top of the fence. So every 10 or 20 feet, put up a slender 15 foot pole/branch. They think the fence is all that tall. (northwest anyway, :)

and the mailbox- i don't know if if would discourage like it does for snails - but the guys reccomended i use copper tape around my pots of cactus. and not a single snail tresspassed. i wonder if perhaps 6 or 8 inches of copper tape around the pole- maybe that will deter them.

sometimes too, animal person recognize medicine or juju. it is not unusual in spirit practice, for the food that is arranged for a spirit and put outside - to not be eaten by animals. They recognize the difference. One time i could only get rid of a possum by praying to my ellegua (trickster spirit) and asked him to bless a pile of sawdust, which i sprinked around like salt for a vampire, and the possum left me in peace. its always good tho, i stop, look and listen, and try to understand the dynamic of the other being, from its perspective, and see if there are any alternatives you can offer that would be more beneficial or desirable for them. then everybody wins. sometimes i would go nuts with my medicine plants being eaten too much. i always preceded every evicition with a converstation with them regarding the need to leave enouph for it to keep growing and producing.

the deer and such stopped being a problem when i put mosquito net over the door,and left it open, my dogs loved to bark and chase them around in the night.

and the only thing that discourages coyote, for me, was my ritual bullroarer. If there were getting to be too large of packs (for safely of animals and neighbors and dogs, etc) i would speak to the sky in the night with the bullroarer. they can hear its tone for miles, and it has a tendency (90% for me) to send the crowd to the other side of the plateau for their night romps.
