Hiring an exterminator costs $400 to $600 on average for rodent removal, but costs can reach up to the thousands, depending on the type of pest, the size of your home, and the extent of the infestation. Raccoons, squirrels, and bats tend to be the most expensive rodents to eradicate.
Rodents do several things that can cause significant structural damage the longer they are in the home, including chewing through walls, destroying insulation, and chewing through electrical wiring, adding the risk of fire to your list of problems. So, you may be dealing with several other repair costs in addition to the cost of the actual extermination.
