Meet the Pest Control Crew Serving Illinois Homes
Last Updated: 10/24/2026
Why We Started Treating Illinois Homes
Illinois Pest Pros is a single-state pest control company we work in Illinois and nowhere else. That focus matters because the pests here run on a calendar. Spring brings ant trails and overwintering stink bugs waking up behind siding. Summer pushes wasp nests into eaves and mosquitoes into shaded yards. By fall, mice start looking for wall cavities in older framing.
Daniel Mercer founded the company after more than 11 years of working homes and businesses around Oak Brook, where basements and aging wood taught him that no two buildings fail the same way. Our technicians hold Illinois Department of Agriculture commercial pesticide applicator licensing, and we maintain National Pest Management Association membership.
Most customers call us after something has already crossed a line droppings in a pantry, bites after a night’s sleep, mud on a foundation wall. We inspect before recommending treatment, explain findings in plain language, and set clear expectations for what treatment and follow-up will look like. That’s the whole promise, and we keep it simple on purpose.
The People Who Show Up at Your Door
Daniel Mercer runs the crew. “I started in pest control working in homes and businesses around Oak Brook, where I learned how basements, older wood framing, and changing Midwest seasons shape pest problems,” he says. “I built this company to bring careful inspections and clear treatment plans to customers throughout Illinois, from termite and rodent issues to seasonal mosquitoes and wasps.”
The team coordinates inspection and treatment visits across Illinois, matching schedules and service plans to each property and pest concern. Before leaving a job site, technicians explain what they found, what they treated, and what follow-up steps if any the homeowner should expect.
Here’s a detail we care about that many crews skip: we check the sill plate and foundation joint where the basement meets the framing. In Illinois housing stock, that seam is where mice and pavement ants get in first, and treating the wrong entry point wastes everyone’s time. Practical pest control across Illinois means knowing the building, not just the bug.

How We Work, Step by Step
Every job starts with an inspection no exceptions. We look at the structure, the moisture conditions, and the pest evidence before we quote anything. Then we explain the recommended control plan in plain terms and set expectations for treatment and follow-up.
Our standards follow the rulebooks that govern this trade in Illinois. Technicians are licensed under the Illinois Structural Pest Control Act and the Illinois Pesticide Act, and we apply products according to their FIFRA pesticide labels the use directions on the label are law, not suggestions. Chemical handling follows the OSHA Hazard Communication Standard for labels and safety data sheets, and any hazardous pesticide waste is managed under RCRA requirements.
One detail an out-of-state contractor often misses: Illinois requires a licensed commercial applicator for structural treatments, and our state runs that licensing through the Department of Agriculture, not a county office. We also time exterior work around Illinois weather a soil barrier applied before a hard freeze doesn’t do what the label intends. Getting the season right is part of doing the job correctly.
