I find big black carpenter ants and their mounds in my Lake tahoe home. I have Bifen IT (I use for ticks), Phantom, Advance 375 A Ant Bait and Optigard. I really like the effectiveness of Phantom, I spray it once every three months on the exterior of my house in the bay area and I never see an ant. Which if any of these should I use or should I get something else?
Phantom concentrate is really designed for use inside, so we would not recommend spraying it outside. You can spray the Phantom along baseboards and in cracks and crevices inside. Termidor SC is the companion product to Phantom, and it is for outdoor use and is excellent for ant control and is also labeled for spiders. You should not spray on top of baits since this could make them less attractive to the ants. Both ant baits you have are labeled for carpenter ants and would be a good start. We also have a Carpenter Ant Kit that includes baits specifically formulated for carpenter ants.
