There is very little odor with Premise Foam.
The problem with treating powder post beetles in furniture, and I presume that is what you are dealing with, is that they are not a "social" insect with kings or queens and there is no nest or colony. So there are no actual galleries that lead to a nest. There is no nest to be killed, the wood is just infested with premature beetles, larvae and pupae. The adult beetles do not stick around. They leave immediately after they "pupate" or emerge from their pupal casing. What you are trying to kill are actually the "worms" or larvae, and pupae. Often called "wood worms".
The holes you are talking about are called "exit" holes. That means that those holes are the holes in which adult beetles have already exited the wood. Treating those holes is useless. The beetles are gone since they have already "exited" the wood.
The only way to treat powder post beetles in most cases, is to saturate the wood 100% with some chemical that will soak into it and kill the beetles. Bora Care, Termidor and others will do this. The only remaining problem is that of some finish, paint, lacquer, etc that will impede the penetration of the chemical into the wood. Most of the time, unless you can remove any finish by sanding, etc, spraying these chemicals directly onto the finish will stop the penetration. Sort of like spraying water on wax paper. It won't soak through and won't work.
Fumigation is normally recommended for furniture. This is something you will have to hire a professional fumigator to do. Vikane and Methyl Bromide gases which are used in fumigation will completely saturate the wood and kill the beetles. This is the only sure way to kill them. You cannot purchase these gases without proper certification and licensing. You will have to "hire it out".
