Why Rodents Keep Coming Back
Rat & Rodent Control in Pasadena: Getting Rid Is Only Half the Job
Most people have rodents removed — and a few weeks later, they're back. The reason is almost always the same: nobody found where they were getting in.
Rodent exclusion focuses on exactly that. We inspect the property, locate every opening rats or mice are using to enter, and seal those access points using professional-grade materials. Then we address the rodent activity directly.
Without closing the entry points, removing rodents is a temporary fix. Other rodents find the same openings. The problem returns.
- Identify active entry points used by rodents
- Seal openings with appropriate professional materials
- Address current rodent activity — non-toxic methods
- Help prevent rodents from re-entering those same access points
Know Your Enemy
Roof Rats & Norway Rats in Los Angeles County
Los Angeles County has two dominant rodent species. Identifying which you have determines exactly where we look and how we seal your home.
Roof Rat (Rattus rattus)
The most common species in Pasadena. Agile climbers that nest in attics, palm trees, and rafters. They enter through rooflines, gaps around pipes, and open vents.
- Entry: roofline, attic vents, pipe gaps
- Nests: attics, false ceilings, wall cavities
- Sign: scratching sounds at night above your head
- Can squeeze through a gap the size of a quarter
Norway Rat (Rattus norvegicus)
Larger and more aggressive. Norway rats burrow in underground tunnels, crawl spaces, and at ground level. Common in older Pasadena homes with crawl space access.
- Entry: foundation gaps, crawl space vents
- Nests: crawl spaces, wall bases, below decks
- Sign: burrows in yard, gnaw marks at ground level
- Can enter through gaps as small as half an inch
Not sure which species you have? We identify both during the free inspection. Call (626) 770-6959.

"We'd been dealing with rats for two years and had several companies come out, but nobody could find where they were getting in. Nathan came out the day after we called, inspected everything thoroughly, and showed us the entry points others had missed. The crew returned the next day and sealed them all. After two years of frustration, we finally felt like we were in good hands. Highly recommend!"

Common Warning Signs
Signs You Have Rats or Mice in Your Pasadena Home
Rodents are rarely seen in the open. These are the signs most people notice first — if any of these sound familiar, a rodent inspection is the right next step.
Scratching or Scurrying Sounds
Sounds in walls, ceilings, or attics — especially at night — are a common indicator of rodent activity.
Rodent Droppings
Small dark droppings near food, in cabinets, along walls, or in attic spaces indicate an active rodent problem.
Chewed Wires or Materials
Rodents gnaw constantly. Chewed wiring, wood, insulation, or food packaging are clear signs of their presence.
Nesting Material
Shredded insulation, paper, fabric, or plant material gathered into a nest indicates rodents are living in your structure.
Visible Rats or Mice
Seeing one rodent — especially during the day — often suggests a larger population is already established nearby.
Rodents Keep Returning
If rodents were previously removed and are back, the entry points were likely never properly addressed. Exclusion is the answer.

Common Questions
Frequently Asked Questions — Rodent Exterminator Los Angeles County

Rodent exclusion is the process of finding and permanently sealing the specific openings that rats or mice use to enter your home. Traps and bait only remove existing rodents — new ones find the same entry points days or weeks later. Exclusion stops the cycle at the source. We inspect the entire exterior, identify every gap, crack, or pipe penetration being used, and seal them with professional-grade materials built to last.
The two most common species in Pasadena and throughout Los Angeles County are the roof rat (Rattus rattus) and the Norway rat (Rattus norvegicus). Roof rats are agile climbers that typically nest in attics, rafters, and palm trees — they enter through rooflines, gaps around pipes, and vent openings. Norway rats are larger, burrow in the ground, and tend to enter at ground level through foundation gaps or crawl spaces. Identifying the species helps us target the right entry points.
For most residential properties, the exclusion work itself takes one day. The inspection, entry point identification, and sealing are typically completed in a single visit. If attic vacuum, sanitization, or insulation replacement is also needed, that may require a second scheduled appointment. We'll give you a clear timeline during the inspection.
Yes. We do not use rodenticides, toxic bait stations, or chemical sprays as part of our standard exclusion work. Our methods are mechanical — sealing, trapping, and sanitation. There are no chemical re-entry waiting periods. Your family and pets can be home during and after the work with no health concerns from our methods.
Rodent droppings, urine, and nesting material left in an attic are a serious health hazard. They can carry Hantavirus, Salmonella, and other pathogens that circulate through your HVAC system into living areas. Rodent waste also soaks into insulation, degrading its R-value. Our attic vacuum and sanitization service removes all contaminated material, and we can replace damaged insulation to restore both your health safety and energy efficiency.
No. We use only non-toxic, mechanical methods. We do not place rodenticide bait stations or use toxic chemicals as part of our work. This is a deliberate choice — exclusion is a permanent solution that doesn't require ongoing chemical use or create secondary poisoning risks for owls, hawks, and pets.
Yes. Our rodent exclusion work comes with a 1-year warranty. If rodents re-enter through any point we sealed within the warranty period, we return and address it at no additional charge.
Yes. Rodent Exterminator is licensed by the California Structural Pest Control Board (SPCB License #10219) and fully insured. Our license covers structural pest control work across Los Angeles County and surrounding areas. You can verify our license at the CPCB's public license lookup.
