Holly, a rodent detection dog, has marked 10 years of service in Brisbane CBD as part of a program that continues to manage rat and mouse activity across homes and businesses in the city.
Historical Role in Public Health
Brisbane’s rodent detection program has operated for more than a century, originally formed in response to a plague outbreak. In the 1950s, BCC teams routinely eliminated thousands of rats each month using dogs and baiting techniques. BCC records show that in October 1951, more than 6,000 rats were destroyed, with a further 1,600 captured the previous month.

Modern Detection and Training Approach
Today, the focus has shifted from eradication to detection and prevention. Dogs such as Holly, a fox terrier, recently recognised for 10 years of service on 3 June, are deployed to detect rodent presence in Brisbane CBD and surrounding areas. These dogs are trained over the course of a year to identify rodent scents and locate potential nests.
Fox terriers are selected for their strong scenting ability and calm temperament. They work alongside handlers and respond to several dozen call-outs per week, inspecting over 500 properties annually. When rodents are detected, BCC officers may advise property owners on prevention methods, such as sealing cracks and improving waste management.
Rodents in Urban Areas
Rodents found in Brisbane CBD typically include large sewer rats, which burrow under buildings, and smaller climbing rats that inhabit ceilings and wall cavities. They are known to damage doors, skirtings, food containers, machinery, and wiring. BCC warns that both types pose serious health risks as carriers of disease.

Invasive Species and Reporting
Rodents are classified as invasive species, contributing to biodiversity loss and public health concerns. BCC encourages residents to report suspected infestations through its 24-hour contact centre on 07 3403 8888 or website. Prompt investigation enables early intervention before infestations grow.
Public Reflection and Community Engagement
Brisbane residents have recalled past visits from BCC rat catchers and their dogs. One resident reflected on her experience in the 1980s when a dog team visited her Balmoral property, describing the encounter as memorable.
Ongoing Role in the CBD
Despite changes in method and scale, rodent control remains active across Brisbane, including the CBD. Holly and fellow detection dogs such as Rosie and Molly have supported the program, with ongoing deployment across both commercial and residential areas. Upon retirement, the dogs remain with their handlers as companion animals.
