Ghost ants are a pain but easily exterminated by studying their movement for a few minutes to see where they are coming from. You will quickly see a line of marching soldiers coming and going on a straight path. Once you find their entrance and exit points you will know where to place liquid bait traps which are very effective (purchase at Lowe's...are inexpensive). Place the traps near their travel line and at the point of entrance and they will take the bait back to the nest and kill the colony. I was told by an exterminator at a seminar years ago to NOT kill them as they actually are very intelligent and each evening when they return home, they do a headcount and if soldiers are missing, they will find another path to travel in your home. After 24-48 hours, they will be gone and then I spray the entrance points with insecticide to prevent future infestation. I have lived in 3 homes in TV and each has had one brief episode with ghost ants, and they have not reappeared.
