Year-Round Pest Protection in Chicago with the Chem-Wise Tri-Annual Plan
Protect your home from ants, spiders, crickets, and dozens of other common pests with Chicagoland's most trusted seasonal treatment plan. Upfront pricing. No hidden fees.
Most pest problems don't happen once—they follow the seasons. Ants push indoors in the spring. Wasps and spiders peak in the summer. Mice and stink bugs look for warmth in the fall. Treating pests reactively means you're always one step behind.
Chem-Wise Pest Control solves this with our Tri-Annual Service Plan: three targeted exterior and interior treatments timed to each season, all backed by a year-round guarantee. Serving the entire Chicagoland area—including Naperville, Aurora, Joliet, Schaumburg, and Rockford—our certified technicians stay ahead of the pest cycle so you don't have to.
What's Included in the Tri-Annual Plan
The Tri-Annual Plan is Chem-Wise's most comprehensive residential pest control service, designed to cover the full pest calendar from spring thaw to fall freeze.
Three Scheduled Treatments Per Year
We visit your home three times—spring, summer, and fall—applying targeted treatments at each visit to address the pests most active during that season. No scheduling hassle. We keep you on the calendar automatically.
Exterior Barrier Treatment
Every visit includes a perimeter barrier treatment around your home's foundation, entry points, and exterior walls to prevent pests from getting inside in the first place.
All Common Crawling Insects Covered
The plan covers all standard crawling insects, including:
- Mice & Rodent Control: Fall and winter invaders that squeeze through gaps as small as a dime, nesting inside walls, attics, and cabinet voids.
- Pavement ants: Common spring invaders clustering along driveway cracks, sidewalk seams, and concrete kitchen slabs.
- Spiders: Frequent summer nuisances thriving in dark, undisturbed areas like basements, garages, and crawlspaces.
- Crickets & earwigs: Moisture-loving summer pests that breed heavily in damp mulch beds and slip under ground-level doors or into lower levels.
- Millipedes & centipedes: Seasonal pests that seek out high-humidity zones like crawlspaces, sump pump areas, and lower-level utility rooms.
- Pillbugs & silverfish: Destructive pests that hide in dark, humid spaces like bathrooms, laundry rooms, or damp foundation soil.
- Boxelder bugs, clover mites & stink bugs: Frustrating seasonal invaders that gather on warm window sills or cluster by the hundreds on sunny exterior siding.
- Roach Treatment: Persistent and fast-breeding pests that thrive in warm, moisture-rich areas. Included in standard service; a higher rate applies for the initial cleanup visit.
- Carpenter Ant Treatment: Destructive wood-boring pests that excavate galleries inside structural timber and wall voids. Included in standard service; a higher rate applies for the initial cleanup visit.
Year-Round Guarantee: If a covered pest returns between your scheduled visits, we come back at no extra charge—as often as needed—until the problem is resolved. No phone tag, no fees, no runaround.
