We recommend that they are not present during the application of Arilon Insecticide until completely dry/ventilated and then it is safe for their return.
Arilon Insecticide was discontinued and has been replaced with Advion WDG Insecticide which is labeled for ants in general but label does not specify pharaoh ants. For pharaoh ants, you could use Phantom Insecticide (indoor use only) or Alpine WSG (indoor and/outdoor).
