Ant swarm outside

Seeing ants around your home? What looks like a small problem can quickly turn into a full infestation. Ants will invade kitchens, walls, and living spaces in search of food and water. Our exterminators specialize in controlling various species of ants, including:

Carpenter Ants, Odorous House Ants, Pavement Ants, Pharaoh Ants, and Flying Ants.

If ants have made it inside your home, the colony is already established. Talk to a professional today!

Signs of an Ant Infestation in your Home

- You notice a trail of ants moving toward food or water.
- Ants appear mostly in the morning or evening, especially in kitchens.
- You see ants near sinks, dishwashers, or trash areas.
- Small piles of debris or dirt appear near baseboards or cracks.
- You keep seeing ants even after cleaning or using store-bought sprays.

Many customers tell us they “only saw a few ants” at first. In reality, those ants are scouts from a much larger colony hidden somewhere in or around the home.

Think you've got Ants?
Act now!

Ant infestations can spread quickly, contaminating food and creating unsanitary conditions.

Ants are social insects that rely on scent trails to locate food and guide other members of the colony. Once a food source is found, hundreds or even thousands of ants can follow the same path into your home.

Because colonies often contain multiple workers and queens, infestations can grow rapidly if not treated properly. Simply eliminating one queen will not be enough to stop the infestation. The sooner you act, the easier it is to eliminate the problem completely.


Common Ants in Philadelphia

Different ant species require different treatment strategies. Ant colonies typically consist of workers, reproductive ants, and one or more queens responsible for laying eggs. In Philadelphia homes, we commonly see:

Odorous House Ant

Odorous House Ants

These are the most common indoor ants. They form large colonies and often have multiple queens, making them difficult to eliminate. They follow scent trails and nest inside walls, under floors, or near moisture. Crushing them releases a strong odor, often compared to nail polish remover or blue cheese.Unlike most ant species, odorous house ants have more than one queen. This makes it very hard to get rid of them as the queens keep making more ants.

Carpenter Ant

Carpenter Ants

Carpenter ants are larger ants that tunnel through damp or damaged wood to build nests. Unlike termites, they do not eat wood, but their nesting behavior can still weaken structures over time.This species of ants is commonly in older Philly homes or areas with moisture issues like basements.Their nests are hard to find and since a single queen can reproduce up to 50,000 worker ants, it is best to leave this to professionals.

Pavement Ant

Pavement Ants

Pavement ants love warmth and moisture. They typically nest in soil, cracks in foundations, or under sidewalks.They enter homes in search of food and water, especially during warmer summer months. They rely heavily on scent trails to guide other ants to food sources.

Flying Ant

Flying Ants

Flying ants enter homes through small cracks, gaps around windows and doors, or openings in walls, in search of food and light. Seeing them indoors can be a warning sign that a nearby colony is active.


Our 3-Step Ant Control Process

Most DIY solutions only eliminate visible ants. Our process targets the colony nests to fully exterminate the infestation.

Ant Inspection

We locate active ant trails, nesting areas, and entry points. Ants use scent trails to travel between food sources and their colony, which helps us trace infestations back to the source.We inspect wall voids, foundations, moisture areas, and exterior entry points.

Stop the infestation before it gets worse...

If you're seeing ants regularly, the infestation is already established.

The sooner it's treated, the easier it is to eliminate completely.

Frequently Asked Questions

Ants enter homes through small cracks, gaps, and openings while searching for food and water. They use scent trails to guide other ants to the same location, which is why infestations can grow quickly.

Most store-bought treatments only kill visible ants. The colony, including the queen, remains hidden and continues producing more ants. Professional treatments target the entire colony to stop the infestation at the source.

Yes. Ant colonies can contain hundreds to thousands of ants, depending on the species. Some species also have multiple queens, allowing colonies to grow and spread quickly.

Ants eat a wide range of foods, including sugars, proteins, and fats. Their food preferences can change throughout the year, which is why different baiting strategies are used for effective treatment.

Some infestations show immediate reduction after treatment, but complete elimination may take multiple visits depending on colony size and location.
