Halogenated hydrocarbons covers a lot more than just DDT.

All the persistent ones are banned for crops in any reasonable country.
Some may still be used for termite control, but few people eat wood.

But the problem with POP's was that the invertebrates getting some dosage
from the wood etc. were eaten by animals higher up the food chain.

I really don't think that's a major problem and although there may be
quite a bit of wood treated it will be peanuts compared to the millions
of acres of cotton sprayed until the 70's in the west, and late 90's in
russia. On top of that the wood in houses doesn't typically re-enter the
biosphere for very many decades.
