This is also called budding. After spraying, your problem can be worse than at the beginning. When you bait, you will want a slow acting bait. Quick kill insecticides and baits will only kill the foraging ants, not allowing the foraging ants to take the bait back home to feed the queen, nest workers and brood. If the current ant bait that you are using is not acceptable to the ants, if they are not visiting the bait, it is recommended that you change the baits.
Ants require carbohydrates-sugars, proteins and greases.
They find a variety of these sources in nature. Choosing a bait would require knowing what they are currently feeding off of, according to the nutritional needs of the colony. Ghost ants tend to forage in a more random pattern than does the pharaoh ant, so that feeding trails may be more difficult to recognize. These ants have a high need for water and may be commonly found in or around kitchens, baths or other moisture sources. Ghost ants are found in warm climates and can be a big problem in tropical areas of the world.
