The best approach to ant control in the home is cleanliness. Any type of food or food particles can attract and provide food for ants. Store food in tight containers. Remove plants that can attract ants or control aphids, whiteflies and other insects that produce honeydew. Reduce moisture sources, including condensation and leaks. Inspection. Location of the nest is the key to control because ants are social insects. Large numbers of individual ants can be killed without ever solving the problem. Determine the kind of ant species. Most species of ants never enter buildings; others build their nests near buildings and forage indoors. Others usually nest indoors.
Keep a record of where ants have been seen. Some ants follow definite trails. If possible, follow these trails to the nest. Placement of attractive materials, such as jelly, oils, protein and other materials can attract large numbers of ants so they can be followed to their nest.
Often children like to watch ants and can be very useful in tracing their trails. Outdoors, ant nests can often be located by seeing ant hills on the ground. Some ants deposit earth on the soil surface when they construct the nest. Fire ants and certain other ants build conspicuous mounds. Nests may also be constructed next to or under the house foundation, under sidewalks, driveways and patios, or in decaying logs or tree trunks.
Indoors, ants may nest in walls, behind a baseboard or under the house. Often ant trails enter through a crack but the nest may be some distance away. Some ants may also nest in decayed or rotting wood in the house.
