Pest controllers have been called out to Ninewells Hospital more than 300 times over the past two years.
Details released by NHS Tayside in response to a Freedom of Information request have documented pest control incidents.
NHS Tayside has a local pest control contract in place and is called out to deal with outbreaks of pests as they occur.
The total cost associated with the services of the outside pest control agency between November 29 2013 and October 7 2014 was £67,124.94.
Among the most common intruders were insects such as ants, wasps, flies and silverfish.
But there were also callouts involving rabbits, dead bats and pigeons, woodlice, ladybirds, rats, mice, seagulls and, in one case, a dead fox.
At Ninewells Hospital, there have been 301 separate incidents that required pest control experts.
The infestations occurred in a range of locations, including wards, kitchens and offices.
A spokeswoman for NHS Tayside said: “It is important to note that our records show what is reported to the pest control company at the time of call-out and not necessarily what is found when they attend the site.
“NHS Tayside has more than 135 premises across the region and in each there are procedures for dealing with pest control problems.
“Whenever a member of staff identifies any type of problem, no matter how small, our pest control contractors are called in straight away.
“All reports are dealt with as a matter of urgency to ensure there is no escalation of any problem and incidents are resolved quickly and effectively.”
