I've applied Phantom ll twice in 4 weeks and my Carpenter ants still are active.
Please be patient using a transfer kill like of Phantom Termiticide/Insecticide does take time. It can take at least 3 weeks to start to maintain control of an ant colony. Also, keep in mind for peak effectiveness, only reapply once every 21 days. We have more tips in our Carpenter Ant Treatment Guide here.
