Fire Ants nest in the soil, often near moist areas. The sting of a fire ant swells into a bump, causing pain and irritation, especially when stung in the same place several times. The bump when left alone will go away on its own within a couple days but it can become infected if scratched.
Carpenter Ants build their nests outdoors seeking wood sources like tree stumps, firewood or landscaping. They mainly attack wood that is or has been wet, decayed and damaged by mold but is not uncommon for them to build paths through dry, clean, undamaged wood as well. Carpenter ant bites may break the skin, leaving big bite marks, resembling pea-sized red blemishes taking just over a week to disappear completely. The same acid found in bee stings, the carpenter ant can inject into the wound during a bite, making the pain very painful. Although the bite is very painful, the stings do not contain venom or transmit diseases.
Argentine Ants prefer moist environments near food sources. They do not normally sting or bite as they do not have stringers, although they can when provoked. They tend to crawl over garbage, dead animals, sewage, or anywhere with a food source making this dangerous as it poses threat for contamination, germs, or even diseases. Argentine ant colonies have multiple queens and will sometimes join together with other colonies to create one large colony, thus an infestation.
Odorous Ants can live almost anywhere, in a variety of conditions. The odorous ant will nest in soil beneath stones, boards, logs, wall voids, water pipes, heaters, under sinks, behind cabinets and beneath the floor. Odorous house ants do not sting or bite but if squished they can be very smelly. The queens in the odorous ant colony are capable of producing thousands of workers and hundreds of reproductive ants making them highly reproductive.
Pavement Ants got their name due to their tendency to burrow under and leave mounds of dirt on top pavement to make their homes. They can nest under stones, along curbs, in cracks of pavement or foundation, along sidewalks, driveways, patios, inside walls and even under flooring. Although pavement ants can bite and sting, they normally will not. If stung it may leave a small red mark on your arm and can easily be eased by icing the area.
