Rodent Control in Southern California

Rodents in your home or yard can quickly become more than just a nuisance. Norway rats, roof rats, and house mice can damage property, contaminate food, spread bacteria, and reproduce rapidly if left untreated. Because rodents can squeeze through surprisingly small openings, they often gain access to attics, crawl spaces, walls, garages, and outdoor areas before homeowners even realize there’s a problem.

Preventive Pest Control provides professional rodent control services for homes and businesses throughout Orange County, Los Angeles County, and the Inland Empire. Our team works quickly to eliminate active infestations and help prevent rodents from returning, giving you long-term protection and peace of mind.

Do You Need Rat and Mouse Control?

Frequently, it’s hard to see rodents because they are active at night, but signs of their presence are easy to detect. Taking the time to check for signs of rodents could be what protects your property from costly damage, dangerous infestations, and spoiled food. Listed below are the surefire signs of a rodent problem:

Droppings & Signs of Activity

Rodent droppings are one of the most obvious signs of an infestation. Mouse droppings are small and pellet-like, while rat droppings are larger and more oval-shaped. You’ll typically find them near food sources, along baseboards, inside cabinets, or in hidden areas like attics and garages. Fresh droppings are dark and moist, while older ones become dry and crumbly.

Scratching in Walls or Ceiling

Scratching, squeaking, or movement inside walls or ceilings is often an early sign of rodents. Rats and mice are most active at night, so these sounds are usually easier to notice when the house is quiet. You may hear them moving through insulation, wall voids, or attic spaces. Frequent or worsening noises often indicate growing rodent activity.

Rodents Entering Your Home

Rodents can squeeze through surprisingly small openings around foundations, vents, utility lines, doors, and windows. Once inside, they search for food, warmth, and nesting areas in places like attics, walls, and crawl spaces. If these entry points are not sealed, infestations can continue growing over time.

Nesting & Outdoor Activity

Rodents build nests using materials like insulation, cardboard, paper, and fabric. These nests are often hidden behind appliances, inside walls, or in storage areas. Shredded materials or debris piles are common warning signs. Finding nesting activity usually means rodents have settled in and may already be reproducing nearby.

Gnawing & Property Damage

Rats and mice constantly chew to keep their teeth from overgrowing, often damaging wood, plastic, furniture, and food packaging. In severe infestations, rodents may chew through electrical wiring, increasing fire risk. Damage is commonly found in hidden or low-traffic areas where rodents are nesting.

Unusual Odors or Hidden Issues

Strong, musty odors can signal a rodent infestation, especially in enclosed spaces like attics, cabinets, or crawl spaces. As droppings and urine accumulate, the smell often becomes more noticeable over time. In some cases, foul odors may indicate a rodent has died inside a wall or hidden area.

Preventive’s Southern California Rodent Control Resources

There’s no doubt that mice and rats are some of the nastiest pests to deal with. And let’s be honest, DIY methods like peppermint oil or store-bought traps don’t always cut it. Fortunately, Preventive’s technicians aren’t afraid to face the issue head-on and bring proven methods of successful rodent extermination so you can experience a pest-free property. Our exterminators will analyze your rodent infestation and determine the best course of action. We offer several rodent control methods depending on the severity of your pest problem. Below is an overview of the rodent control services we offer:

Trapping

Preventive’s most effective method to control rats and mice once they’ve entered a property. Our technicians will thoroughly inspect your home or office and place traps in targeted, discreet areas where rodents are detected or most likely to travel.

Our trapping services include:

Strategic trap placement for maximum effectiveness
Targeting high-activity rodent pathways
Regular follow-up visits to monitor activity
Our team handles cleanup and trap maintenance
Customized treatment plans based on infestation severity

With decades of experience, we know exactly how many traps are needed and where to place them to help eliminate rodent activity efficiently.

Exclusion

Preventive’s preferred long-term solution for keeping rodents out of a building. Sealing cracks or openings larger than ¼ inch to prevent rodents from re-entering the structure.

Common rodent entry points include:

Cable and phone line openings
Water pipe gaps
Foundation cracks
Dryer vents
Drain ports
Air conditioner condenser lines
Roofline gaps and openings

Our technicians carefully inspect the property, identify vulnerable areas, and provide a clear, transparent quote for recommended exclusion.

Baiting

Rodent baits are Preventive’s primary method for controlling rodent populations outside structures. Bait stations help reduce overall rodent activity around homes and businesses before pests move indoors. We comply with all California laws regarding the use of rodenticides.

Our baiting services help:

Reduce outdoor rodent populations
Target recurring rodent activity areas
Monitor changing pest pressure around the property
Support long-term rodent prevention strategies
Protect homes and businesses from future infestation

When food, water, and shelter are available, rodent populations are bound to increase quickly. Strategic population control outside the structure is often necessary to prevent future infestations.

 Trustindex verifies that the original source of the review is Google. Over the years ... I have been very impressed with all of your professional technicians... as each is qualified and conscientious. BUT... I believe Sam is one of your better technicians. He is punctual, friendly, attentive to my needs, respectful of me and my property and very through in completing his task. He insures that what we need is taken care of properly and completely. His efforts prove that he strives for satisfaction rather than simply going through the motions to pacify us. Thank you for keeping my property pest free... but I really appreciate that your staff will respond immediately should a problem develop. Keep up the excellent work. These days it is difficult to find a "Customer Service" company with such high standards.
