A rat exterminator costs $150 to $600. Extermination fees are highest for large infestations in the attic, crawlspace, or basement that typically require the most repairs. The cheapest rates apply when you catch a few rats before they start breeding.

Rat removal costs more for:

• Attic insulation replacement costs $2 to $6 per square foot. Replacing insulation contaminated with rat droppings is one of the most common repairs.
• Roof repair costs $150 to $400 to fix holes created by roof rats.
• Drywall repair costs $200 to $750 after removing rats from inside a wall.
• Crawl space repairs and cleaning cost $200 to $700 after fixing a minor rodent problem, and a cleanup after a large infestation costs $1,500 to $4,000.

Rat exterminators are worth it for their experience in problem solving large infestations with safe removal methods. A professional can guide you on how to avert future infestations by pinpointing and sealing entrances used by the rats. Rat extermination is a must to prevent disease transmission.

Rat infestation signs that it's time to call an exterminator are:

• Gnawed holes in walls or fences
• Bitten objects
• Small animal footprints outside
• Scratching noises in the walls, attic, basement, or crawlspace
• Uncommon and strong odors
• Fecal droppings or holes up to 2" wide in baseboards or doors
• Dirty smears (body oils) on walls

An exterminator will get rid of rats with techniques like trapping, poisoning, applying repellents, blocking all entrance points, and performing regular inspections. Although traps are efficient for dealing with single rats, poisoning demands time. The effectiveness of these approaches varies depending on the situation.

Eliminating rats could take a few days with traps or up to a week with rat poison, depending on how many rats you have and the method of removal. Dealing with larger rat infestations takes more than a month.

Completely rat-proofing your home with sealants can take up to 3 days. Rats are resistant to change, so they don't fall for baiting and exclusion easily.

Prepare for rat extermination by organizing your home, blocking entry points, and removing food and water sources that may attract pests.

Additional crucial preparation steps include:

• Putting food in sealed containers
• Relocating your pets during the extermination
• Fixing holes in walls
• Cleaning the areas under the sink and above the fridge
• Refraining from using pesticides before professional treatment

You can get permanent rat eradication by:

• Blockading all holes and cracks wider than 1"
• Keeping all their food sources well-sealed and out of reach
• Fitting one-way exclusion doors on vents
• Minimizing potential outdoor habitats around the house where they can hide

Implement these measures after professionals have cleared all rats from the home's interior. Exclusion doors are most effective at ensuring rats leave before they die within the property.
