A-1 Pest Master provides licensed pest control across Chicago and Chicagoland, covering ants, cockroaches, bed bugs, earwigs, termites, rodents, and nuisance wildlife for homes and businesses. We've handled inspections, targeted treatment, and follow-up visits since founder Isaac Hill started the company in August 1984, and our technicians take emergency calls around the clock.

What Pest Control Services Do We Provide in Chicago?
We provide general pest control, wildlife removal, termite inspection and extermination, ant control, earwig control, cockroach control, bed bug treatment, and bee and wasp removal, along with rodent control, fumigation, preventive treatments, and 24-hour emergency service for both homes and commercial accounts.
That list breaks down into two broad categories, insect and pest control on one side, wildlife on the other, and we cover the full range on both:
- Pest Control Services: ants, earwigs, cockroaches, bed bugs, bees, wasps, hornets, fumigation, and preventive treatments.
- Wildlife Removal Services: white-footed mice, squirrels, raccoons, snakes, possums, and general rodent, rat, and mice control.
- Termite Inspection & Extermination: inspection and long-term treatment for termite activity.
- Ant Control & Removal: species identification, trail and nest treatment, and prevention.
- Earwig Removal & Control: moisture-driven infestations in basements and crawl spaces.
One reviewer, Peyton Brooks, wrote in a Google review: "The technician spent extra time answering all my questions about humanely handling wild squirrels and possums around the yard. I'll definitely be using A1 Pest Master for all our future pest needs!" That mix of insect and wildlife work under one visit is common for us, not the exception.
How Our Pest Control Process Works
Every service call follows the same basic structure, whether it's a single ant trail in a kitchen or a full commercial account. We start with an inspection to identify the pest and locate where it's entering, feeding, or nesting. For ants, that means finding the colony and its trails; for cockroaches, it means checking kitchens, storage rooms, basements, and other hidden spaces for nests and activity.
From there, we build a treatment plan specific to the pest and the property, apply it using targeted products and baiting methods rather than blanket spraying, and follow up. Follow-up visits and sanitation recommendations matter as much as the initial treatment. A termite job that skips the follow-up inspection isn't finished; a cockroach job in a multi-unit building rarely is either, since one untreated unit can reinfest the rest of the building.
Jason Collins put it this way in a Google review of our termite service: "Thorough termite inspection and totally honest evaluation. Loved supporting a solid local business that delivers quality service without trying to force unnecessary treatments."
Common Pests We Treat in Chicago Homes and Businesses
| Pest | Size / ID | Where we find it | Notes |
|---|---|---|---|
| Ants | 1.5 to 13 mm, three body segments, live in colonies with a queen | Kitchens, pantries, walls, floors, cracks, patios | Follow scent trails to food and moisture |
| Earwigs | 5 to 25 mm (1/4 to 1 inch), dark brown, pincers | Basements, crawl spaces, under mulch and wood piles | Active mostly at night, drawn to moist, dark spots |
| Cockroaches | Varies by species | Kitchens, apartment buildings, multi-unit dwellings | Activity surges in July and stays elevated through summer in apartment settings |
| Bed bugs | Small, flat, reddish-brown | Bedrooms, upholstered furniture, multi-unit rentals | Chicago has a specific landlord response timeline, covered below |
| Termites | Varies by species and stage | Foundations, wood framing, moisture-prone areas | Inspection first, then long-term protection |
Do We Offer 24-Hour Emergency Pest Control in Chicago?
Yes. We run a 24-hour emergency pest control service for urgent infestations, meaning a call about an active bee nest, a rodent problem, or a sudden roach outbreak gets a response outside our regular office hours as well as during them. Our standard office hours are Monday through Friday, 9 AM to 5 PM.
An active wasp nest near a doorway or a rodent chewing through a kitchen wall doesn't wait for business hours, so the emergency line exists for exactly that kind of call. Our regular hours cover routine inspections, scheduled treatments, and follow-up visits.
Residential and Commercial Pest Control Across Chicagoland
We serve two distinct audiences, and the pest pressure on each is different. On the residential side, we treat houses, apartments, and condos throughout Chicago, Chinatown, Berwyn, and the surrounding suburbs. On the commercial side, we work with restaurants, offices, warehouses, schools, dealerships, hotels, apartment buildings, and public and institutional properties, plus property managers and real estate professionals who need pest issues resolved before a sale or lease closes.
Commercial accounts tend to carry higher stakes: a roach sighting in a restaurant kitchen or a rodent problem in a warehouse can shut down operations or fail an inspection. That's part of why our commercial process leans on the same inspection-treatment-follow-up structure, just scaled to a larger property and, often, a recurring schedule.
What Does Illinois Require of Pest Control Companies?
Illinois requires a commercial structural pest control business to employ at least one certified technician, and each technician has to score at least 70 percent on every required certification exam. The Illinois Department of Public Health oversees that certification and licensing structure for the whole state.
That standard sets a real floor for who's allowed to treat a Chicago property commercially. Our technicians are licensed and certified under that framework, and we're a member of the Illinois Pest Control Association as well.
What Happens If a Tenant Reports Bed Bugs in a Chicago Rental?
Chicago Municipal Code 7-28-830 requires a landlord to arrange bed bug pest control by a pest management professional within 10 days after a bed bug is found or reasonably suspected, or after a tenant gives written notice. That 10-day window applies to the landlord's response, not to how long treatment itself takes.
We handle those calls for property managers and landlords across Chicago and the surrounding suburbs, and we treat bed bugs as a time-sensitive job because of that 10-day requirement, not just because infestations spread fast between units.

Frequently asked questions
How often should I schedule preventive pest control in Chicago?
Preventive treatments typically run every few months for most homes and businesses, though some pests need more frequent visits depending on how bad the activity is and what's driving it. A basement with a chronic moisture problem, for example, usually needs a tighter schedule than a dry, well-sealed home.
What should I do if I find bed bugs in a Chicago rental unit?
Notify your landlord in writing right away. Chicago Municipal Code 7-28-830 gives landlords 10 days from that notice, or from when bed bugs are found or suspected, to arrange treatment through a pest management professional. We work directly with landlords and property managers to meet that timeline.
Do you offer one-time treatments, or only recurring service plans?
Both. A single visit handles a specific problem, like a wasp nest or an ant trail, without committing to a standing schedule. Our preventive treatment service is the recurring option, run every few months for most properties, with more frequent visits when a particular pest calls for it.
Which Chicago pests are most active in summer?
Cockroach activity surges in July and stays elevated through the summer, especially in apartment buildings and other multi-unit dwellings. Earwigs are also more active in warm, moist conditions, and ants forage more aggressively as they search for food and water sources around homes and yards.
