yes, u can buy chlorpyrifos or cypermathrin from any hardware shops and spray by yourself or contractor. after spray,u can coat the roof truss with with the common wood stain ( kind of paint), for door etc u can either piant wiht wood stain if u want to see the wood grain or normal paint (eg alkyd, polyester etc) to cover the toxic chemicals. (non translucent)
roof - make sure that u spray on both end /cut and nail spot coz termite can go in from here.
those treated wood is usually in greenish color but sometime sawmills cheat consumers with pigments.
common chemicals for wood use in outdoor is CCA (copper chrome arsenic) - green in color
some of them cheating by jsut soak with CCA to show it is green color. it shud be pressure reated , force the chemicals to go inside the wood cells. the longer time , the higher the pressure hte better.
anyway, they are too many cheating outside. in fact u dun have to spray if it is proper treated. spray is short term. pressure treat is longterm and wood can last more than 100 years. the wood primeter is deeply cover with chemicals, nailing have no affect.
