Termites have four wings of equal length, while ants have wings of unequal lengths. Most ants feed on the same foods that humans do. Some types of ants are attracted to greasy foods, while others prefer sweets. Whichever type they are, when workers locate the food that their colony likes, they will lay down a chemical signal as a trail for other workers to follow to the source of the food. This is why large numbers of ants can be observed in the same spot.
Habitat alteration means changing the environment so that it is less appealing to the worker ants.
This can include simple changes, like storing food in sealed containers, keeping fruit in the refrigerator, washing dirty dishes and keeping countertops clean. Other changes may take more effort, like caulking around windows and doors, having adequate screening and reducing outdoor sites where ants can have colonies. Toxic baits and sprays are good tools to use for ant control. Ant sprays applied to cracks and crevices will help control ants for a short time. Never spray entire floors, walls, counter tops, or the insides of drawers or cabinets.
