A hospital in Canada has been compelled to indefinitely postpone surgical procedures following an invasion by a resilient ant species. Carman Memorial Hospital, situated in the small town of Carman, approximately 50 miles southwest of Winnipeg, has rescheduled and relocated 16 elective surgeries to alternative facilities.
Scope of the Infestation
The Southern Health Authority, which manages the hospital, informed CBC that the duration of the surgical suspension remains uncertain. However, officials assure that there is no risk to staff or patient safety, nor any structural damage to the building. The postponed surgeries include hernia repairs and gallbladder removals, with the hospital coordinating with surgeons to reschedule them at other locations.
The ants have not affected other hospital services, only those requiring sterile environments. Residents needing emergency surgeries will be transported to the nearest alternative hospital. Health Minister Uzoma Asagwara stated, 'Every effort is being made to minimize disruptions and restore normal services as soon as possible.'
Extermination Efforts
Exterminators have been dispatched and are actively working to eliminate the pests. Carman Memorial Hospital has experienced seasonal ant invasions for the past two years. The ants, believed to be pavement ants (Tetramorium immigrans), were first spotted in 2024, with the problem resolving naturally after a few weeks. They reappeared the following summer, prompting action from the region. This spring marks the third occurrence, leading the health authority to seek more extensive, long-term solutions.
Southern Health indicated that the current number of ants does not constitute a full infestation but suspects a nearby colony is seeking food sources. Exterminators have surveyed and cleaned drains, sealed cracks, and placed sticky tape and bait to locate the ants' entry points. Rob Higgins, a retired entomology professor specializing in ants, commented, 'I'm really not aware of many places that have successfully permanently dealt with pavement ants,' suggesting the challenge of eradication.
The Daily Mail has contacted Southern Health Authority for further comment.
