The council’s pest control experts tackled 630 cases including flea and rat infestations in the borough last year.
Richmond Council spent more than £53,000 on external companies to respond to complaints, including 150 about mice and 22 about bedbugs, in 2011-12.
A total of 734 people raised concerns about rats and the authority took action in 448 of these cases, according to Freedom of Information figures.
The council’s bug experts were less busy last year than in 2010-11, when they responded to 855 treatment requests.
They carried out 746 pest control missions in 2009-2010.
A total of 38 people have also complained to the council about squirrels, cockroaches and pigeons in the past three years, but the authority does not provide a service to tackle these.
