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. Inside they are usually found in the kitchen and bathrooms , but workers are seen trailing along window sills, and baseboards. They can also be spotted near sources of water in the kitchen and bathrooms, counter tops, toilets,drains and sinks. They prefer to nest in recessed areas like wall voids,under some appliance, wall outlets, under carpet for protection.
