Pharaoh ants are not that easy and the gel in our kit says it may not work for Pharaoh so best not to go with the kit. You can try Maxforce FC Ant Bait Gel which is labeled for Pharaoh ants.
Also, if you see a lot of ants outside around the perimeter of your home and around in the garage, you might want to try Termidor SC or just use it in addition to the bait. Termidor is for outside use only around the perimeter of your home. Label directions for perimeter pest application are on the last page of the product label. A new generic version called Taurus SC is also available. This product is unique in that the ants that cross over it will get it on themselves and transfer it back to all of the other ants in the colony. Similar to a bait but you don’t have to worry about bait acceptance. The container makes 24 gallons so you will have it for years. Again, it can not be used indoors.
