How long does one application of Phantom last?

I am having an ant infestation problem, particularly between the drywall and the cement board and tile of the shower wall. I'm having it redone, but once it goes up, I'm not sure how to reapply.


Phantom will last for about 90 days indoors and for about 30 days outdoors. You can apply Phantom in problem areas outdoors to avoid having the ants move back into the wall void. You may also want to consider using a dust such as Mother Earth D that can keep killing insects indefinitely when placed in the wall void.
