Ant Control
No matter how your home is built, where it’s located, or how old it is — ants can find a way in. They’re the number one nuisance pest in the United States, and west side Cincinnati homes are no exception. Odorous house ants trail through kitchens after every rain. Carpenter ants hollow out wood framing in older homes. Pavement ants push up through foundation cracks. At Delhi Pest Control, we’ve been eliminating ant infestations for west side Cincinnati homeowners for over 40 years — and we know exactly where they’re coming from and how to stop them.
Types of Ants We Treat in Cincinnati
Odorous House Ants
The most common ant complaint on the west side. These small brown ants smell like rotten coconut when crushed — hence the name. They trail in through the smallest cracks in search of food and moisture, and can establish multiple satellite colonies inside your walls. Standard over-the-counter sprays often make infestations worse by causing colonies to split.
Carpenter Ants
Larger black ants that don’t eat wood — they excavate it to build nesting galleries. Common in older Delhi Township, Westwood, and Cheviot homes with any moisture-damaged wood. A carpenter ant infestation can cause significant structural damage if left untreated. If you’re seeing large black ants inside your home, especially near windows or wooden beams, call us promptly.
Pavement Ants
Small dark ants that nest under sidewalks, driveways, and foundation slabs — pushing small piles of dirt through cracks in concrete. Common throughout Cincinnati’s west side neighborhoods. They forage inside homes for grease, sweets, and pet food.
Pharaoh Ants
Tiny pale yellow ants that are notoriously difficult to eliminate without professional treatment. They nest deep inside wall voids and can have multiple queens, making DIY baiting counterproductive. Common in multi-unit housing and older apartment buildings.
Small Black Ants
A common nuisance species that nests outdoors in soil, mulch, and under rocks — foraging inside through foundation gaps and window frames. Typically respond well to exterior barrier treatments.
Our Ant Control Process
Every ant infestation is different — the species, the entry points, and the nesting location all affect how we treat it. That’s why every service starts with a proper inspection.
Inspection
We identify the ant species, locate the entry points, and assess whether the colony is nesting inside your home or entering from outside. This determines which treatment approach will work.
Treatment
Depending on the species and severity, we use a combination of exterior liquid barrier treatments, targeted interior gel bait applications, and crack-and-crevice treatments. For carpenter ants and Pharaoh ants, we use specialized approaches that target the colony directly rather than just the foraging ants you can see.
Prevention
We identify and seal common entry points, recommend habitat changes around your foundation, and provide guidance on reducing the conditions that attract ants — moisture, food sources, and harborage areas near your home.
Follow-Up
For persistent infestations or ongoing protection, we offer quarterly service plans that maintain a barrier around your home year-round.
Why Ant Problems Are Worse in Spring and After Rain
Ant activity spikes on the west side every spring and after heavy rainfall — both events disturb outdoor colonies and drive foraging ants indoors in search of food and dry shelter. If you’re seeing ant trails inside your home after rain, the colony is almost certainly nesting outdoors and entering through your foundation or siding. This is actually good news — exterior barrier treatment is highly effective in these situations. If ants are present year-round regardless of weather, the colony has likely established itself inside your walls and requires a different approach.
