Rodent Control Illinois
Rodents—including the widespread House Mouse and the destructive Norway Rat—are far more than just small, furry annoyances when they invade your home; they represent a significant and costly threat to your safety and property. While it’s always an unpleasant surprise to spot a mouse or rat skittering across the floor, the real danger lies in the rodents you don’t see. They are experts at exploiting tiny entry points and quickly taking up hidden residence in the nooks and crannies you might overlook, such as inside walls, under floors, and in rarely-used storage areas.
Once established, an infestation explodes rapidly due to the rodents’ prolific breeding cycle. A single female house mouse can produce several litters per year, with up to half a dozen babies every three weeks, meaning a small entry problem can quickly overwhelm your home in just a few short months. Beyond sheer numbers, rodents cause structural damage through persistent gnawing, which they do constantly to wear down their incisor teeth. This destructive behavior targets vital home components, including PVC piping, insulation, and even electrical wiring, which presents a genuine fire hazard. Furthermore, their continuous droppings and urine contaminate food sources and surfaces, exposing your family and pets to serious health risks like Salmonella and Hantavirus.
Given the serious health consequences and the extensive damage rats and mice inflict, a proactive and professional approach is essential. If you hear scratching in the ceiling, find droppings, or suspect an infestation, it is vital to contact experienced exterminators immediately. Don’t waste time or money on ineffective DIY solutions. For permanent relief and peace of mind, contact the expert rodent exterminators at Garella Pest Services. We will perform a comprehensive inspection, identify every entry point, and implement a targeted, reliable solution to eliminate the infestation and secure your property for good.

Signs of Rodent Activity
The safety concerns that come with a rodent infestation are enough to make even the most vigilant homeowners nervous. Fortunately, mice and rats leave tell-tale signs that they’ve invaded your home. If you notice any of the following, contact Garella and we’ll send our highly-experienced, friendly exterminators your way:
- Rodent droppings, which look like brown pellets, around the house.
- Gnaw marks on baseboards, walls, or home goods.
- Scratching and skittering sounds from within walls or the attic, especially at night.
- Greasy rub marks along walls and baseboards.
- Nests made of paper, cotton, or fabric within unused drawers or boxes.
- Actual rodents, dead or alive.
What Makes Rodents Dangerous?
Like most pests, rodents get into your home seeking warmth, shelter, food, and water. Rats can fit through openings the size of a quarter and mice only need an opening as small as a ballpoint pen. That means no matter how clean your house is, rodents can still find their way in. Left unchecked, a rodent infestation poses health and safety dangers to your family, including:
- Carrying dangerous diseases such as typhus and jaundice.
- Food contamination if they gain access to your kitchen.
- Structural damage as they chew through insulation, wood, and more.
- Electrical fires can result if they chew through wires.
- Noxious odors from waste or dead rodents.
