pest control in Cook County

Your home is your sanctuary. With Landmark's Complete Home Care program, you get proactive, year-round protection against over 40 common pests — including ants, mice, spiders, wasps, and more. This program is designed for homeowners in Cook County who want to stop invasions before they start, rather than reacting after damage is done.

What's Included: Quarterly expert inspections and treatments, indoor and outdoor crawling insect barriers, proactive stinging insect nest prevention, spider web removal, a mouse monitoring system, and a complimentary mouse exclusion inspection. All methods are approved for use in homes with children and pets, using low-impact products that work with nature.

Why choose us: Our science-based protocols mean we don't just spray and leave. We identify entry points, harborage areas, and attractants specific to your property. As a local company serving Cook County for decades, we understand which pests are most active each season. Enjoy a pest-free home all year long without worrying about stinging insects, ants, mice, or unexpected infestations.

Take back your backyard. Landmark's mosquito control service targets these biting pests at their breeding sites using environmentally friendly larvicides and adulticides. We serve residential and commercial clients throughout Cook County who want to enjoy their outdoor spaces without constant swatting and itching.

Our Process: A certified technician will inspect your property for standing water, dense vegetation, and other mosquito harborage areas. We then apply targeted treatments to shrubs, lawns, and fence lines where mosquitoes rest. Treatments are effective yet safe for bees, butterflies, and beneficial insects. We also educate you on simple steps to reduce future breeding, like removing standing water and cleaning gutters.

The Landmark advantage: Our mosquito control is not a one-time fix. We offer recurring treatments aligned with the mosquito life cycle, ensuring long-term reduction. Backed by the same scientific rigor as our other services, you can trust that your backyard will be comfortable for summer barbecues, playtime, or quiet evenings.

Mice and rats don't just invade your space — they chew wires, contaminate food, and spread disease. More than a pest control company, Landmark is a pest exclusion company. We permanently seal rodents out using proprietary techniques and rodent-proof materials. This service is critical for Cook County homeowners and businesses dealing with recurring rodent issues or seeking prevention.

What we do: A full inspection of your home's exterior and interior to locate all possible entry points — as small as a dime for mice. We then seal gaps around pipes, vents, foundations, roofs, and garages with steel wool, caulk, metal flashing, or other durable materials. Once sealed, we set safe traps to remove any rodents already inside. Finally, we clean and sanitize affected areas.

Why exclusion matters: Trapping without sealing wastes time and money because new rodents will find the same openings. Our approach stops the cycle. With over four decades serving Cook County, we know the common construction types and weak spots in local homes. Don't wait until you hear scratching in the walls — proactive exclusion is the most effective and humane solution.
