Which rodents live around Joliet.
Norway rats are the other usual suspect. They burrow along foundations and enter low. House mice are the most common rodent in Joliet homes. They're small, curious and breed quickly.
Dense shrubs against the house and a dripping hose bib give rodents cover and water. Trimming back and fixing drips makes the yard less inviting.When they move in.
Spring is breeding season. Check for gaps before then. Small problems grow fast.

A year of rodents in Joliet.

Mice or rats?
- Behavior: mice are curious about new traps. Rats avoid them for days. - Sounds: mice sound light and quick. Rats sound heavier. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized. - Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger. - Rub marks: rats leave greasy smudges along walls and beams.
Sealing small gaps yourself.
- Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put. - Steel wool or copper mesh: pack it into small gaps first. - Check your work: daylight through a gap means it isn’t sealed.
Cleaning up droppings safely.
- Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves. - Air the room out for 30 minutes first. - Wash your gloved hands, then your hands.
What happens at an inspection.
They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first. Most inspections take about an hour. Photos help. You should come away with a list of entry points. Inside, they check the kitchen, garage and attic.
Rodents in the car.
Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring. Clear birdseed and pet food from the garage. Check the air filter box for nesting.
Bird feeders and rodents.
Use a seed tray and sweep up spills. Spilled seed feeds mice and rats. Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- Is cleanup included, or extra? - What happens if they come back? - How many trap visits are included? - Which gaps will you seal, and with what? - Where are they getting in? - Will you use poison inside? (Ask them not to.)
Ways to keep the cost down.
- Act early, before rodents spread to the attic. - Trim branches back from the roof. - Store food and pet food in sealed bins. - Clear clutter so gaps are easy to reach. - Compare what each quote seals, not just the price.

- Local labor rates and licensing costs.
- Outdoor pressure from creeks, alleys, or restaurants nearby.
- Home size, stories, and roofline complexity.
- Whether insulation must be removed and replaced.

- Follow-up visits included versus billed separately.
- Materials used for sealing: mesh, sheet metal, mortar.

Call right away if you see rats. They take a longer, more careful approach. Attic cleanup is hard to do safely without training. Call if you hear them in the attic or walls. Droppings in several rooms are another sign. So is a dead-rodent smell.
What you can do yourself
Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off. Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins.
