A giant rats nest has been destroyed in a southern Alberta city fighting to get rid of the rodents.
An official in Medicine Hat says staff from the city, the county and the province got rid of an 80-metre-long nesting site at the landfill on Tuesday.
Ed Jollymore says no live rats were found.
Alberta's rat-free status was put into question last month when the nest was discovered at the dump.
Medicine Hat residents called in dozens of sightings and at least 100 Norway rats were killed by city staff.
Jollymore says it took six hours for 21 workers and two excavators to dismantle the nest.
He says officials will continue to monitor the area and put out poison bait as part of "Operation Haystack."
Poisoned hay bales have been dropped around the city to try to stop the flow of vermin into neighbourhoods.Albertans cheered the declaration the province's assault on the rodents had met with success and some even showed their provincial pride upon hearing the rat's Alberta invasion had come to an unfruitful end.
Agricultural fieldmen known by Albertans as the "rat patrol"' have worked for years targeting invading rats within a control zone along the province's eastern boundary. Pet rats are also forbidden under provincial law.
