Pavements ants are mostly considered nuisance pests. While they have a stinger, they rarely sting people, and a sting from a pavement is generally too weak to penetrate the skin. For those who are sensitive, a bite from a pavement ant can cause skin irritation or a rash. These ants are not venomous and their bites are not medically important.

If pavement ants come into your home, they can present a small health concern. These ants can crawl around in your trash and then climb on food prep surfaces, dishes, silverware, and get into stored foods. When they do this, they can spread harmful bacteria like salmonella.

Salmonella is a nasty bacterium that thrives in the intestinal tracts of animals and humans and can cause food poisoning. The resulting illness can range from mild to very serious infections that can kill vulnerable people. Most salmonella infections can be classified as stomach flu and signs and symptoms may include nausea, vomiting, abdominal cramps, diarrhea, fever, chills, headache, and blood in the stool. These symptoms generally last 2 to 7 days, and diarrhea can last up to 10 days. Furthermore, it can take several months before bowel function returns to normal.

Most of the time, the problem these ants present is the unsightly way they can completely cover a dropped potato chip or mob the food in a pet dish. They do not present serious issues like carpenter ants or imported fire ants.

Identifying Pavement Ants

A worker ant of this species measures around ⅛ - 1/16 of an inch long and can be dark brown or black, with parallel lines on its head and thorax and pale legs and antennae. If you're able to capture one of these ants with a piece of tape and examine it up close, look to see if it have two nodes between the thorax and abdomen.

Flying ants of this species are about twice the size of the workers. They also have a lined head and thorax. Spines are evident on winged females but are absent on the males. Flying ants usually swarm in spring but have been known to emerge any time of the year if they have established themselves inside heated structures. Once flying ants mate, they shed their wings, and the queen moves into her new home and begins laying eggs. New worker ants will develop over a 2 to 3 month period.

One of the best ways to identify pavements ants is to look where they prefer to build their colonies and forage. Most colonies are established underneath sidewalks, building slabs, and large rocks. But they often enter into buildings through foundation cracks or cracks in interior slabs. If you see sand piles and small soil particles in structures near cracks in concrete slabs, this is indicative of ants that have invaded and pushed out this material from excavated nests. And pavement ants have the ability to multiply quickly. In some species, one ant queen can lay hundreds of thousands of eggs in a single day! Worker pavement ants can live for up to 5 years, with queens living much longer.

DIY Ant Control

While there are several DIY products available that promise to help you eliminate ants, these products are mostly ineffective and they can actually make your problem worse. The biggest problem with DIY ant control is that many ant control products, like insecticide spray, are often misapplied (which can result in harm to people or pets). And these sprays do nothing to solve the root of an ant infestation. Because of this, reintestation is likely to occur again and again.
