Tempo 1% Dust would be a great choice to dust in a wall void for carpenter ants. Dusts do tend to kill the ants a bit faster than foaming but you may need to drill more holes or open the wall a bit more to make sure you are getting even coverage. Please take a look at our Carpenter Ant Control Guide for some great information about dusting and other products you can use in a wall void.
