How Professional Exterminators Get Rid of Rats for Good

by | Apr 16, 2025

Rats are more than just a nuisance—they pose serious health risks, cause property damage, and multiply at an alarming rate. A single pair of rats can produce hundreds of offspring in just one year, quickly turning a small problem into a full-blown infestation. These rodents contaminate food, chew through wiring, and spread dangerous diseases like hantavirus and leptospirosis. Getting rid of rats requires more than setting a few traps; it demands a strategic, expert-driven approach to eliminate them at the source.

The First Step: Identifying the Scope of the Infestation

Professional rat exterminators don’t rely on guesswork. The rat infestation removal process starts with a detailed inspection to determine where the rodents are nesting, how they’re entering the property, and what’s attracting them in the first place. Rats are nocturnal and excellent at hiding, so a thorough assessment includes checking crawl spaces, attics, walls, and even HVAC systems where they often seek shelter.

Exterminators look for signs like droppings, gnawed surfaces, oily rub marks along walls, and nesting materials. This information helps them develop a targeted plan that addresses the infestation at its core, ensuring that rats are not just removed but prevented from returning.

The Extermination Process: More Than Just Traps

Many homeowners attempt to handle rat infestations on their own using store-bought traps and poisons. While these methods may catch a few rats, they rarely eliminate the entire problem. Professional rat exterminators use a combination of advanced techniques to ensure complete eradication.

Baiting and trapping are commonly used, but they are strategically placed based on the behavior of the rodents. Professionals use commercial-grade bait that is more effective than over-the-counter options. Some infestations require sealed bait stations, which attract rats and eliminate them in a controlled manner without posing a risk to children or pets.

For severe infestations, exterminators may use exclusion methods to physically block entry points while strategically reducing the rat population. Integrated pest management techniques ensure that once the rodents are eliminated, they don’t have a way to reinfest the property.

Sealing Entry Points: The Key to Long-Term Prevention

One of the biggest mistakes homeowners make is focusing only on killing the existing rats without addressing how they got inside in the first place. Professional exterminators not only remove the current infestation but also implement exclusion techniques to keep rats from coming back.

Rats can squeeze through openings as small as a quarter, making it crucial to seal cracks, vents, and gaps in the foundation, roof, and walls. Professionals use steel wool, metal flashing, and other durable materials to block entry points, as rats can chew through softer materials like wood and plastic. By cutting off access, exterminators prevent future infestations before they start.
