Pest controllers in the north of the county are called out an average of six times a day to deal with infestations.
Figures have revealed pest controllers were called out 6,963 times by Kettering, Corby, Wellingborough and East Northants councils over three years.
Rats and mice were the biggest problem, with the councils sending pest controllers 1,221 times to deal with infestations from April 2012 to April 2013.
During this time East Northants Council sent its pest controllers to 532 infestations of rats, compared to just 103 call-outs for rat infestations by Kettering Council.
East Northants Council has dealt with a higher number of infestations over the period.
The council’s deputy leader, Glenn Harwood, says there is a number of reasons for this.
He said the area the council covers is more rural, and it also tackles more because it has two pest controllers in-house, one full-time and one part-time.
He added that the council offers to deal with first-time rat infestations for free, which helps them give advice to residents.
He added: “By offering to do this for free we can help more people.
“Whereas at other councils they perhaps charge, meaning more people are likely to not ask for help.”
