I've read a little on the "butt and pass" method of log building.
A method that eliminates the need for notches at the corners to tie the logs together, but requires rebar to hold the logs in place. Looks to be quicker, eliminates scribing the logs then cutting the notches.
I've read a lot about traditional log building, and types of joinery/notches used on the corners
Need to read more about butt and pass. Thanks for showing me the technique.
The considerations for the logs should be the same either way.
I've not had troubles with PPB in cherry, but they love maple and ash.
You should be able to find recipes to make borate solutions to treat wood/lumber. Search here, forestry forum, and another good site to bookmark The Woodweb.com
This won't kill bugs already in the wood, but will prevent further infestations. Works on lots of different insects, kills ants, termites. Disadvantage is it will wash off, so treated wood needs to be covered from weather.

"I'll stick to the home chemistry part of the question. If you want to use boric acid it takes borax and boric acid combined to make DOT, the borate you want. The U.S. Navy spec. is 60% borax-40% boric acid (this ratio gives the maximum solubility of borates in water). To make this solution mix 65% water, 20% borax, 15% boric acid and heat until dissolved. I don't do it that way myself, I like the easy way. I buy 50 lb sacks of Solubor and mix at a rate of 1 lb/gallon of water for a 10% solution. At 1.5 lb/gallon it’s a 15% saturated solution that is stronger but will crystallize overnight so it must be used up when you mix it and clean up any spray equipment really well."
Besides specific wood formulas below, borates are used in agriculture so farm supply stores may carry suitable products that can be used on wood.

Swallowing small quantities (one teaspoon) will cause no harm to healthy adults. If larger
amounts are swallowed, give two glasses of water to drink and seek medical attention.
Use eye wash fountain or fresh water to cleanse the eye. If irritation persists for more
than 30 minutes, seek medical attention.
No treatment necessary.
If symptoms such as nose or throat irritation are observed, remove to fresh air.

Most important symptoms/effects, acute and delayed
Inhalation : No known significant effects or critical hazards.
This product is not intended for ingestion. Small amounts (e.g., a teaspoon) swallowed
accidentally are not likely to cause effects; swallowing amounts larger than that may
cause gastrointestinal symptoms. Symptoms of accidental over-exposure to high doses
of inorganic borate salts have been associated with ingestion or absorption through large
areas of severely damaged skin. These may include nausea, vomiting, and diarrhoea,
with delayed effects of skin redness and peeling.
