Who This Is For
This guide is for homeowners, landlords, restaurant owners, and families in Detroit who are dealing with ants and want a safe, effective solution. Whether you have small children or pets, need to protect your property investment, or run a food business, professional ant control can eliminate the problem and prevent future invasions.
The Problem
ants are the most common household pest in the United States, and Detroit's urban environment provides abundant food and shelter. Pavement ants nest under sidewalks and foundations, entering homes through cracks. Carpenter ants, which are larger and can cause structural damage, are attracted to moist or decaying wood—common in older Detroit homes. During spring swarms, winged carpenter ants may be seen indoors, signaling a nearby nest. Odorous house ants, named for the rotten coconut smell when crushed, form massive colonies and forage along trails. Fire ants, while not native to Michigan, have been introduced and can inflict painful stings; their colonies can contain up to 500,000 workers. Nationwide, fire ants cause an estimated $6 billion in damage and control costs annually.
Warning Signs
- •Seeing live ants, especially in kitchens, bathrooms, or along baseboards.
- •Ant trails: lines of ants moving between a food source and a nest.
- •Small piles of sawdust or wood shavings near baseboards or windows, indicating carpenter ants.
- •Rustling sounds in walls or woodwork from carpenter ant activity.
- •Winged ants (swarmers) indoors, often near windows or light sources in spring.
- •Ant nests in soil, under mulch, or in potted plants, often seen as small mounds.
- •Odorous house ants emit a rotten coconut smell when crushed.
Risks of Waiting
- ⚠Carpenter ants can cause significant structural damage over time, weakening beams and walls.
- ⚠Ant colonies can grow rapidly; a single queen can produce thousands of workers.
- ⚠Food contamination: ants can infest pantries and spread bacteria.
- ⚠Fire ant stings are painful and can cause allergic reactions in sensitive individuals.
- ⚠Property value may decrease if damage is left untreated.

Treatment Options
Baiting Systems
$150-$300Gel or granular baits are placed along ant trails. Workers carry the poison back to the colony, killing the queen and the rest. Effective for most ant species.
Perimeter Spray Treatment
$200-$400A residual insecticide is applied around the home's foundation, windows, and doors to create a barrier. Kills ants on contact and deters new ones.
Carpenter Ant Drilling & Injection
$400-$600Small holes are drilled into infested wood, and insecticide dust or foam is injected directly into the nest. Requires locating the nest, which may involve non-invasive detection.
Integrated Pest Management (IPM)
$300-$500A comprehensive approach combining inspection, sanitation, exclusion (sealing cracks), and targeted treatments. Often includes ongoing monitoring.
Understanding Ant Behavior and Colony Structure
ants are social insects that live in colonies with a division of labor: queens reproduce, workers forage and maintain the nest, and males mate and die. A colony can range from a few hundred to hundreds of thousands of individuals. Foraging workers leave pheromone trails to guide others to food sources, which is why you see ant lines. Understanding this behavior is key to control: baits exploit the trail system to deliver poison to the colony. In Detroit, pavement ants often nest under sidewalks and enter homes through slab cracks, while carpenter ants prefer moist wood in attics, porches, or wall voids. Odorous house ants are attracted to sweets and form supercolonies with multiple queens, making them harder to eliminate. Fire ants, though less common in Michigan, build large mounds in sunny areas and defend aggressively.
The Hidden Damage of Carpenter ants in Detroit's Older Homes
Detroit has a large stock of older homes, many with wood framing that can be susceptible to moisture. Carpenter ants don't eat wood like termites; they excavate it to create smooth galleries for nesting. Over time, this can weaken structural beams, floor joists, and wall studs. Signs include sawdust piles (frass) containing wood shavings and ant body parts, and rustling sounds in walls. Because carpenter ants are active at night, infestations may go unnoticed for months. Professional treatment often involves locating the parent colony (usually outdoors in stumps or dead trees) and satellite colonies inside the home. Drilling and injecting insecticide into the galleries is effective, but exclusion and moisture control are essential for long-term prevention. In Detroit's humid summers, keeping basements and crawl spaces dry is critical.
Why DIY Ant Control Often Fails
Many homeowners reach for over-the-counter sprays when they see ants. While these kill the ants you see, they don't address the colony. Worse, some sprays can contaminate bait trails, making baits less effective. Another common mistake is not identifying the ant species correctly. For example, carpenter ants require different treatment than pavement ants. Baits work well for sugar-loving ants but may be ignored by protein-seeking ants. Additionally, if the bait is not placed near the trail or is left out too long, it loses effectiveness. Professional pest control technicians are trained to identify species, locate nests, and choose the right product for the job. They also provide exclusion services to prevent re-entry. With a service guarantee, you're protected if ants return.
Ant Inspection: Four Evidence-Based Checks
A short visual guide to ant trails, carpenter-ant evidence, indoor food and moisture conditions, and exterior entry points.
Read the video transcript
Follow visible ant trails to likely entry gaps and photograph the route before cleaning or sealing. Coarse frass near wood can be evidence of carpenter-ant activity, but identification requires closer inspection. Reduce accessible food and moisture, and inspect plumbing and wall penetrations instead of relying only on surface spray. Check mulch, vegetation, siding clearances, and utility entries. Treatment scope should follow confirmed evidence.

When to Call a Professional
If you see multiple ants daily, find sawdust or wood damage, notice winged ants indoors, or have tried DIY methods without success, it's time to call a professional. Ant Control Detroit offers inspection terms that vary by provider and a service guarantee, so there's no risk in having an expert assess your situation.
DIY vs Professional
DIY ant control can be effective for very small, visible colonies—for example, using over-the-counter baits for pavement ants. However, most DIY treatments only kill foraging workers, leaving the colony intact. Professional pest control technicians have access to advanced baits and insecticides that are more attractive to ants and can eliminate the queen. They also identify entry points and nesting sites that homeowners often miss. For carpenter ants or large infestations, professional treatment is almost always necessary to prevent structural damage. The upfront cost is higher, but long-term results and peace of mind are worth it.
Local Context
Detroit's humid continental climate, with warm summers and cold winters, creates a seasonal ant pressure. Spring thaws and rains drive ants indoors seeking food and shelter. The city's aging infrastructure—cracked foundations, leaky pipes, and wooden porches—provides ideal nesting sites for carpenter ants. Pavement ants are ubiquitous, nesting under sidewalks and driveways, and often enter homes through expansion joints. Detroit's median home value of $85,000 means many homeowners are cost-conscious, but investing in professional ant control can prevent costly structural repairs. Local pest control companies are familiar with the area's common species and effective treatments. For example, baiting programs are popular for odorous house ants, while carpenter ant jobs often require drilling into historic woodwork. Restaurants and food businesses must maintain strict sanitation to avoid ant problems that could lead to health code violations. Ant Control Detroit offers inspection terms that vary by provider tailored to your property, with a service guarantee that ensures peace of mind.
Species and regulation must be checked before treatment
An address alone cannot establish the ant species, nest location, or treatment. Around Detroit, Michigan, follow trails, document entry points, and distinguish coarse carpenter-ant frass, soil mounds, and ordinary foraging before choosing a control method.
Carpenter-ant evidence boundary
University of Minnesota Extension notes that carpenter-ant parent nests are commonly associated with moist or decayed wood, while satellite nests may occur in drier voids. Correct moisture problems and identify the nest rather than treating every large ant as proof of structural damage.
