Carpenter Ant Treatment

A King Crimson Maple in my yard has a carpenter ant infestation within a cavity in the main trunk. Arborist has recommended treatment of the cavity with Astro to manage the ants and then sealing the cavity with foam.

I am considering doing the treatment myself, using Terro Carpenter Ant Killer Aerosol Spray. The active ingredient is the same as in Astro.

Are there any contraindications to me using the Terro product instead of Astro? Would any additional ingredients in Terro harm the tree?
