What Happens When There are Ants in My House?

Ants walk across contaminated surfaces, like the toilet and trash can, and then they walk on food preparation surfaces and on the clean dishes in your cabinets. This is how ants contaminate your home and spread germs, like salmonella.

Landmark’s environmentally-friendly treatments are nontoxic to humans, but effective against ants. Ants carry the treatment back to their colonies and feed it to their queens. Once their colony is destroyed, an effective, invisible barrier is applied to the foundation and other vulnerable areas around your home to keep new ants from coming inside.

Landmark’s Complete Home Care program provides year-round protection warrantied against over 40 different types of pest including ants, bees, wasps, hornets and mice.


Why Don’t Ant Products That I Buy at the Store Solve My Ant Problem?

Over-the-counter products can’t wipe out the infestation completely. They kill only the five percent of ants that you see, but more ants keep coming back because 95 percent of ants are still in the nest.

Our professional-grade products, expertly applied, treat the infestation at its source. Then our barrier treatment leaves an invisible fence of protection to stop future ant colonies from getting inside. The result is a safe, clean, ant-free home.

Why Are There Ants in My House?

There can be hundreds or thousands of ants in each colony. Each ant colony is constantly searching for what they need to survive, food, water, and a warm place to live, so your home has exactly what they’re looking for.

As ants look for resources for the colony, they walk through unsanitary areas, spreading disease wherever they go. Carpenter ants are particularly destructive because they destroy and weaken the wood in your home. Landmark’s targeted treatments use environmentally conscious methods, designed with the biology of the ants in mind, to effectively treat ants at their source, eliminating the colonies quickly, and protecting your entire home or business from future infestations.

They’re looking for shelter. They’re looking for food. They’re looking at your home, no matter where you live. Contact a Landmark pest expert today to get rid of ants quickly.

Landmark Will Make the Ants Go Marching

There are over 22 species of ants in Chicago. The biomass of ants on the planet outweighs that of humans, so it’s no surprise that ants cause more pest control problems than any other insect.

Ant traps sold at the hardware store are ineffective. Landmark’s green methods utilize baits tailored to the way ants feed. Our methods target the colony’s queen, because without her, the colony cannot survive.

Problems Associated with Ants

  • Ants contaminate food and transmit diseases
  • Ants, such as the Carpenter ant can weaken the integrity of structures by hollowing them out to form nests
  • Ants can sting or bite
  • Ants can gnaw into plant beds, defoliate plants, and steal seeds from seed beds


The four most common types of ants in Illinois are Odorous House ants, Carpenter ants, Pharaoh ants, and Pavement ants. Each ant species is treated differently, so our team begins every treatment program by properly identifying the species.

Odorous House Ants

This ant species can be easily identified by its signature odor. When crushed, the Odorous House ant smells like ammonia.

This species can be difficult to control because its colonies generally contain multiple egg laying queens, resulting in vast numbers of ants which spread when part of the colony breaks off to form its own colony, or when part of the colony decides to swarm.

Carpenter Ants

Despite their name, Carpenter ants do not actually eat wood. Rather, they hollow it out to form tunnels and chambers where they live. They have large jaws that can deliver a painful bite.

Homes that have experienced a roof leak or other water damage often have a Carpenter ant infestation, because Carpenter ants prefer moist wood. Common Carpenter ant nesting sites include fence posts, firewood piles, decaying trees, porches, roofing, sub-flooring, doors, wall voids, insulation, and around water sources like bathtubs, dishwashers, showers and sinks.

Pharaoh Ants

Pharaoh ant colonies can contain thousands of members with multiple queens. Unlike other ant species, Pharaoh ants don’t swarm. Instead, they engage in a process known as budding, in which a part of the colony will break off and migrate when the colony starts running out of space or resources.

Pharaoh ant colonies can also be difficult to find, because colony members roam more than 150 feet from their nest. These behaviors can make Pharaoh ants particularly difficult to treat without proper experience and professional tools.

Pavement Ants

Pavement ants prefer to build their colonies beneath rocks or in pavement cracks, excavating sand from crevices in asphalt and concrete. Pavement ants can infest insulation, walls, and floors. They may enter structures through small cracks and crevices.

Ants with Wings

To establish new colonies, reproductive ants develop wings. They fly away from the colony to reproduce and start new colonies of their own. Winged ants are frequently misidentified as termites. Landmark technicians are specially trained to be able to tell the difference and treat the problem correctly.

Pest Control Powered by Science

Ants differ in their behavior, habits, and biology and each species requires a different type of treatment.
