Ants are attracted to greasy or sweet substance and they can enter from the tiniest crack or space available. They leave an invisible chemical known as pheromones which lets other ants follow them and locate the sweet or greasy substance.
Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organized colonies which may occupy large territories and consist of millions of individuals. These larger colonies consist mostly of sterile wingless females forming castes of “workers”, “soldiers”, or other specialized groups. Nearly all ant colonies also have some fertile males called “drones” and one or more fertile females called “queens”.
Eliminating the entire colony is nearly impossible. Pest management is therefore a matter of controlling local populations, instead of eliminating an entire colony, and most attempts at control are temporary solutions.
Ants classified as pests include the pavement ant, yellow crazy ant, sugar ants, the Pharaoh ant, carpenter ants, Argentine ant, odorous house ants, red imported fire ant and European fire ant.
Ant stings are caused by stinging ants, always painful, but most painful when involving fire ants.
