Rat pest control and proofing experts

Expert rat control from Western Exterminator

Rats are more than just an unwelcome sight. They chew through wiring, contaminate food, and can spread serious diseases through their droppings, urine, and nesting material. Once they're in, they breed fast — and a small problem can become a major rat infestation in a matter of weeks.

At Western Exterminator, we've been helping homeowners and businesses deal with rats since 1921. Our pest control experts know how rats think, where they hide, and how to help get rid of them.

Our specialized rat treatment process

Every rat problem is different. That's why we don't use a one-size-fits-all approach. Our rat control services follow a structured, proven process designed to address the problem at its source and help prevent it from coming back.

Inspection

A technician will check your property inside and out, looking for the telltale signs of rats.

  • Identify the rat species
  • Locate active areas and extent of infestation
  • Map existing and potential entry points

 

Treatment

Once we understand the scope of the infestation, we put a targeted rat control plan into action:

  • Traps, selected for your environment
  • Secured bait stations
  • Vegetation management

 

Prevention

Getting rid of rats is only half the job. Keeping them out is just as important.

  • Rat proofing to seal entry points
  • Reduce attractants 
  • Scheduled follow-up visits
  • Advice on exclusion measures

Why you need to act quickly if you see rats

Spotting a rat — or even just the signs of one — is reason enough to call in a professional. Rats don't travel alone, and what looks like a single rat is often a sign of a larger rodent problem nearby. Here's why acting fast matters:

  • Health risks — Rats can spread diseases like Hantavirus, leptospirosis, and salmonella through their droppings, urine, and feces. These can be transmitted directly or through contact with contaminated surfaces. 
  • Structural damage — Rats gnaw constantly. They can chew through wood, insulation, and electrical wiring, which can create a serious fire hazard.
  • Rapid breeding — A pair of rats can produce dozens of offspring in just a few months. The longer you wait, the harder the infestation is to manage.
  • Contamination — Rats infest food storage areas and contaminate surfaces with urine and feces.

If you're seeing any signs of rats, our rat pest control team is ready to help.

Frequently asked questions

A rat exterminator inspects your property for signs of activity, identifies entry points, and uses targeted methods — like trapping, bait stations, and physical exclusion — to help remove rats and prevent them from returning. At Western Exterminator, we also sanitize affected areas to help reduce health risks.

Costs vary based on the size of the infestation, the property type, and the services required. The best way to get an accurate figure is to book a free inspection — your technician will walk you through the options and provide a clear estimate.

Call as soon as you notice signs of rat activity — droppings, gnaw marks, scratching sounds in walls, or a musty odor. The earlier you act, the easier it is to manage. If you've spotted a rat directly, don't wait.

Rats in walls require professional tools and techniques. Our technicians use targeted traps and monitored devices placed at wall voids and access points to address activity in hard-to-reach areas. We also identify and seal the entry points rats are using to get inside.

Yes — especially for ongoing or larger infestations. Professional rat exterminators have the training, tools, and experience to address the root cause of the problem, not just the symptoms. DIY methods can offer temporary relief, but they rarely stop rats from coming back.
