Redwood and Wolmanized Lumber
Although all wood will rot in due time but pine and oak will last longer
PRESSURE TREATED WOOD, CEDAR, REDWOOD
yes. the bark contains a high level of tannin, which keeps bugs out and keeps it from rotting.
the pros of building a floor for a basement out of wood is that if there is some soort of sewage pipe leake then you dont have to pull out the jack hammer or hammer and chisel. the con is termite, ants, insects and, rot
Lumber used to be pressure treated with arsenic - a lethal poison - specifically chromated copper arsenate - which turned the lumber slightly green- but legislation was passed several years ago ( 2003 ) stopping the use of arscenic and going to less toxic substances. Another copper solution called ACQ is used. The copper makes the wood more rot resistant and is toxic to some insect life. Termites would tend to favor untreated wood. While the bottom sill of balloon frame structures may be pressure treated, the framing above the bottom sill is most often not treated. It is too expensive to build structures entirely from pressure treated lumber. The best defense against termites is to keep the wooden parts of the structure well off the soil with stone or concrete foundations and keep those foundation lines clear of flower beds mulched in wood chips so as not to give termite colonies easy access.
No
Redwood, cypress, and cedar are termite and rot resistant. These are softwoods and may not last as long as hardwoods.

Red pine is one of the most used woods in the country. It is not naturally rot resistant, however, it can be protected and treated to ensure that is it can resist rot.
yes. the bark contains a high level of tannin, which keeps bugs out and keeps it from rotting.
The disadvantages of Ash wood is that it is not as rot proof or water resistant as other hard woods. If it is left untreated, it will rot quickly.
Jarrah and Teak last approximately 50 years, and Jarrah is fire, rot and termite resistant, so is a good choice for durability. Other common woods used are Pine, Redwood, Roble and White Cedar. further information on the woods can be gained at http://www.outdoorlivingideas.com/woodtypes.html.
Hemlock is not very rot resistant.
Titanium is highly corrosion-resistant.
Rot-Resistant WoodsA few years ago, redwood was a big no-no for anyone who cared about the environment because venerable old-growth trees were laying down their lives to become lawn furniture. Today, redwood is a renewable resource, as millions of redwood seedlings are replanted every year-about five for every tree harvested. And cedar is an even better choice since it can be forested even more easily and quickly than redwood. Both native woods are naturally rot-resistant. They are good, reasonable, non-chemical alternatives to pressure-treated wood, but they are not totally care-free, and a deck made from either redwood or cedar will still require regular maintenance. Tropical Wood AlternativesThere are other rot-resistant woods that are just coming to the American market, including ipe (also known as ironwood) and cambara. These exotic woods will last for 2o years or more with just one preservative treatment. Ask to see certification of sustainable harvesting methods before you buy any tropical wood products.* http://www.care2.com/greenliving/hit-the-deck-with-nontoxic-solutions.html
