A unitary system of government, or unitary state, is a sovereign state governed as a single entity. The central government is supreme, and the administrative divisions exercise only powers that the central government has delegated to them.
Some people even refer to them as 'piss ants'. However, many types of ants smell bad when you smash them. They are also known as Sugar Ants, they get that name because they readily feed on sugar, pop, syrup, and other sweets. In nature these ants actually eat other insects and insect secretions. Aphids make a sticky 'sap' when they eat the leaves of bushes and trees.
Sugar ants invade homes in the early spring and fall because they are looking for food and a cool, dark, moist, wooded area to make a nest to support their colony. Some older homes tend to attract more of these types of ants because they usually have plenty of cool, dark, moist areas and are much easier to get into.
