Mouse and Rat Exterminator Cost Factors

Your rat exterminator costs depend on a couple of key cost factors. Here’s a closer look at how your total breaks down.

Infestation Severity

The severity of the infestation determines the price because it impacts what treatment methods are necessary and how many follow-up visits the rodent exterminator needs to make. Keep in mind, fumigation is often a last resort. For severe infestations, professional treatment may require fumigation, which costs $1 to $3 per square foot, translating to roughly $2,000 to $6,000 for a 2,000-square-foot home.

Removal Method

You can choose from various methods to catch or kill rodents. We discuss them in detail below.

Live Removal

Live removal costs vary by region, but plan on $50 per rat for trapping and relocation. The added expense comes from relocating the pests at least one mile from any home, which takes time, adds mileage to vehicles, and uses extra fuel. 

Some pros advise against this method for rodents since they’re likely to die outside in the winter. It’s also illegal in some areas to prevent rodents from becoming invasive to new ecosystems and harming the environment.

Fumigation

Rat fumigation costs $1 to $3 per square foot, or $2,000 to $6,000 for a 2,000-square-foot home. However, qualified pros can easily control any rodent infestation with bait, traps, and exclusion; most don't even offer fumigation services. Only fumigate as a last resort. It's disruptive and harmful for several reasons, such as the following:

• Fumigation can expose you, your family, and your pets to chemicals.

• You'll need to move out of your home for a few days.

• It leaves dead rodents to decompose in the walls.

• Chemicals escape into the environment, possibly causing harm.

Lethal Traps

Lethal traps are the most common way exterminators remove rodents from a home. Fees increase if your local rodent exterminator needs to set more than 10 traps.

Trap costs vary depending on the type of trap used, with the most common being traditional snap traps, jaw traps, glue traps, CO2 traps, and electronic traps.

Budgeting for Rodent Extermination

There’s no way to get around paying for rodent extermination when you need it, but there are a few ways you can reduce the costs:

• Schedule a professional inspection, which costs between $100 and $200, to assess the scope of the problem and avoid paying for unnecessary services.

• Consider setting up your own traps if you have a minor infestation.

• Seal any entry points into your home as soon as you notice them—you can also fill cavities with steel wool to discourage rodents from traveling through them.

• Contact a professional pest control technician in your area as soon as you notice rodents, as unchecked infestations can escalate rapidly.

• Pay to have your home professionally sealed after extermination to prevent future infestations.
