Common Ant Species in Lombard and the DuPage County Area

Understanding which type of ant has invaded your space is the first step toward effective control. Different species have unique behaviors and nesting preferences, which dictate the treatment strategy. In Lombard, several species are frequently encountered by pest management professionals.

• Odorous House Ants: True to their name, these small, dark brown or black ants emit a rotten coconut-like smell when crushed. They are attracted to sweets and moisture, often trailing into kitchens and bathrooms. They typically nest outdoors in soil or under objects but will move indoors to wall voids or under floors when conditions are favorable. ¹
• Pavement Ants: These small, brownish-black ants are named for their habit of nesting under sidewalks, driveways, and building foundations. They often enter structures through cracks in the slab or foundation, creating small mounds of soil at their entry points. They have a varied diet but are common invaders of ground-level rooms. ^{2 3}
• Carpenter Ants: Larger than most household ants, carpenter ants are a significant concern because they excavate wood to create nesting galleries. Unlike termites, they do not eat wood but remove it to build their nests, which can weaken structural timbers over time. They are often black or red and black, and signs of an infestation include frass (sawdust-like debris) and rustling sounds inside walls. ^{4 5}

How Ants Enter and Where They Hide

Ants are master explorers, capable of finding the tiniest openings to access the food, water, and shelter inside your Lombard home or business. Their entry points and nesting sites are often hidden, making a thorough inspection critical.

Common Entry Points: Ants exploit gaps as small as 1/32nd of an inch. Key entryways include cracks in the foundation, gaps around window and door frames, utility line penetrations (for pipes, wires, and cables), and through vents. They also use tree branches or shrubs that touch the structure as a bridge. ^{1 6}

Indoor Nesting & Foraging Areas: Once inside, ants seek out protected, humid spaces near resources. Common indoor hotspots include:

• Kitchens & Pantries: Behind and under refrigerators, stoves, and dishwashers; inside cabinets; and along baseboards seeking food spills.
• Bathrooms: Under sinks, around tubs, and near leaky fixtures where moisture is present.
• Structural Voids: Inside wall cavities, under flooring, in ceiling voids, and behind large appliances.
• Basements & Crawl Spaces: These areas often provide the damp, undisturbed environment perfect for certain ant colonies. ^{2 7}

Outdoor Nesting Sites: The colony's main nest is often located outside. Preferred outdoor locations include:

• In soil under rocks, mulch, or landscaping timbers.
• Under concrete slabs, patios, and driveways (especially for pavement ants).
• In rotting tree stumps, firewood piles, or hollow trees (common for carpenter ants).
• Within the insulation of exterior walls or under siding. ⁵

The Professional Ant Extermination Process: What to Expect

Local Lombard pest control companies follow a systematic, multi-step approach designed for long-term success, not just a temporary knockdown. Here's how a typical service visit unfolds.

Step 1: Detailed Inspection and Identification

A technician will conduct a thorough inspection of your property, both inside and out. The goal is to identify the ant species, locate foraging trails, find entry points, and, if possible, pinpoint the nest location. This investigation is essential for choosing the most effective treatment methods. ^{8 9}

Step 2: Customized Treatment Application

Based on the inspection findings, the technician will implement a targeted plan. Modern ant control relies heavily on baits and non-repellent insecticides.

• Baiting: Specialized ant baits are placed along trails and near activity. Worker ants carry the bait back to the colony, where it is shared, eventually eliminating the queen and the brood. This method is highly effective for colony-wide control. ^{10 11}
• Barrier & Crack-and-Crevice Treatments: Insecticides may be applied as a protective barrier around the home's foundation, doorways, and other entry points. Direct treatments are also used in wall voids, under appliances, and other hidden harborages. For carpenter ants, treatments focus on the nest location and surrounding wood. ^{8 12}

Step 3: Prevention and Exclusion Recommendations

A key part of professional service is advising on how to make your property less attractive to ants. This may include recommendations for:

• Sealing cracks and gaps with caulk or other sealants.
• Improving sanitation by storing food in sealed containers, managing trash, and cleaning up spills promptly.
• Reducing moisture by fixing leaky pipes and ensuring proper drainage away from the foundation.
• Trimming back vegetation and moving woodpiles away from the structure. ¹²

Timeline for Results: When Will the Ants Be Gone?

It's important to have realistic expectations after a professional treatment. Ants will not vanish instantly, and seeing more ants shortly after treatment can be normal.

• Initial Reduction (24-48 hours): You should notice a significant decrease in visible ant activity within the first day or two as the treatment begins to take effect. ^{13 14}
• Complete Eradication (Several Weeks): Total colony elimination, especially for large or hidden nests, can take several weeks. Baits work on a delayed timeline, as they must be distributed throughout the colony. It is not uncommon for activity to taper off over 2-4 weeks. ^{13 15 16}
• Follow-Up Visits: For persistent problems or as part of an ongoing service plan, technicians may schedule follow-up visits to monitor bait stations, reapply treatments if necessary, and ensure the infestation is fully resolved.

Understanding Ant Control Costs in Lombard

The cost for professional ant extermination in Lombard varies based on the infestation's severity, the square footage of your home, the ant species involved, and the type of service plan you choose. ^{17 18}

• One-Time Treatment: For a single, targeted service to address a specific ant problem, homeowners can generally expect a range from $150 to $395. This is often suitable for minor, early-stage infestations. ^{17 19}
• Ongoing Service Plans: Many residents opt for periodic services to prevent future issues. These plans often include treatments for other common pests as well.
  • Quarterly Plans: Typically cost between $100 and $300 per quarter.
  • Monthly Plans: Can range from $40 to $70 per month. ¹⁷
• Severe or Specialty Infestations: Complex situations, such as a widespread carpenter ant infestation that requires extensive inspection and treatment inside walls, can cost $800 to $1,400 or more. ¹⁹

The most accurate way to determine cost is to obtain a free, personalized estimate from a licensed Lombard pest control provider. They can assess your specific situation and provide detailed pricing. ^{20 21}
