How to Get Rid of Ants in Your Home

Written by Viking Pest Control | October 1, 2018

If you’ve noticed ants making their way through your kitchen, bathroom, or along your windowsills, you’re not alone. Ants are one of the most common household pests throughout New Jersey, Pennsylvania, Delaware, and the Eastern Shore of Maryland. While small ant problems may seem harmless at first, infestations can quickly grow if the colony is left untreated.

Understanding why ants enter homes, how to prevent them, and when to call a professional can help you protect your home from a much larger infestation.

Why Are Ants Coming Into My House?

Ants typically invade homes while searching for food, water, and shelter. Even the smallest crumbs, spills, moisture issues, or entry points can attract scouting ants that leave behind pheromone trails for the rest of the colony to follow.

Ant infestations often begin outside before spreading indoors. Ants commonly travel into homes by:

  • Climbing tree branches or shrubs touching the house
  • Entering through cracks and gaps around foundations
  • Following plumbing or utility lines indoors
  • Nesting near mulch beds or damp wood
  • Searching for food in kitchens and pantries

Once ants establish a reliable food source inside your home, the infestation can grow rapidly.

Common Types of Ants Found in Homes

Several ant species are common throughout NJ, PA, DE, and MD homes.

Odorous House Ants

 Odorous house ants are among the most common indoor ants. These small brown or black ants are attracted to sweets and moisture. When crushed, they release a strong odor often compared to rotten coconut. 

Pavement Ants

 Pavement ants typically nest under sidewalks, driveways, and foundations. They often enter homes searching for sugary foods, grease, and proteins. 

Carpenter Ants

Carpenter ants are much larger than most household ants and can cause structural concerns. Unlike termites, carpenter ants do not eat wood, but they tunnel through damp or damaged wood to build nests.

Signs of carpenter ants may include:

  • Large black or reddish ants indoors
  • Rustling sounds inside walls
  • Piles of sawdust-like material
  • Moisture-damaged wood

If left untreated, carpenter ants can weaken wooden structures over time.

Why DIY Ant Treatments Often Fail

One of the biggest mistakes homeowners make is only treating the ants they can see. Sprays and store-bought products may temporarily reduce activity, but they rarely eliminate the actual colony.

Most ant colonies contain thousands of ants hidden behind walls, under floors, outdoors, or inside void spaces. Killing visible worker ants usually does little to stop the infestation itself.

Common DIY ant control problems include:

  • Incomplete colony elimination
  • Misidentifying the ant species
  • Using ineffective repellents
  • Driving ants deeper into the structure
  • Missing hidden nests and satellite colonies

Some over-the-counter sprays can even cause ants to split into multiple colonies, making the infestation harder to control.

How Professional Ant Control Works

Professional ant exterminators focus on identifying the species, locating the colony, and eliminating the infestation at the source.

At Viking Pest Control, treatment plans are customized based on the type of ant, severity of infestation, and conditions around the property. Professional ant control may include:

  • Thorough interior and exterior inspections
  • Targeted baiting systems
  • Non-repellent treatments
  • Identification of moisture or food sources
  • Entry point reduction recommendations
  • Long-term prevention strategies

Many professional ant treatments rely on bait systems that worker ants carry back to the colony. This allows the treatment to spread throughout the nest and eliminate the queen and remaining colony members.

Because of this process, it is normal to continue seeing ant activity for a short period after treatment while the colony is being eliminated.

How to Prevent Ants From Returning

 Prevention is one of the best ways to reduce the risk of future ant infestations. Small changes around the home can make a major difference. 

Keep Your Kitchen Clean

Ants are highly attracted to food debris and moisture. To reduce attraction:

  • Wipe down counters regularly
  • Clean crumbs and spills immediately
  • Avoid leaving dirty dishes overnight
  • Store pantry foods in airtight containers
  • Empty trash regularly

Eliminate Moisture Issues

Many ant species seek out water sources indoors. Repair:

  • Leaky pipes
  • Dripping faucets
  • Moisture buildup under sinks
  • Poor ventilation areas

Trim Vegetation Away From the House

Tree branches, bushes, and shrubs touching your home create easy access points for ants and other pests.

Trim vegetation several inches away from siding, windows, and roofing areas.

Reduce Exterior Nesting Areas

Mulch, leaf piles, wood stacks, and debris close to the home can encourage ant nesting activity.

Keep firewood elevated and away from the structure whenever possible.

Seal Entry Points

Inspect your home for small cracks and openings around:

  • Windows
  • Doors
  • Foundations
  • Utility penetrations
  • Pipes and vents

Sealing gaps can help reduce indoor access.

Are Big Black Ants a Problem?

Large black ants inside the home are often carpenter ants, especially if they appear repeatedly or near moisture-damaged wood.

While seeing one or two ants does not always indicate a major infestation, recurring sightings should not be ignored. Carpenter ant colonies often remain hidden for long periods while continuing to expand inside wall voids and wooden structures.

Professional inspection is the best way to determine whether carpenter ants are actively nesting inside the home.

Stop Ant Infestations Before They Spread

Ant infestations rarely disappear on their own. What begins as a few ants in the kitchen can quickly become a much larger colony hidden behind walls or outside around the foundation.
