Taxpayers are footing a record bill for pest control measures at the Scottish parliament.
Thousands of pounds are being spent on trying to get rid of mice, seagulls and pigeons at the Holyrood building.
Pest control measures were stepped up after mice were spotted nibbling on documents and even in food preparation areas.
Last year, a record £22,535 was spent to try and rid the building of the pests.
This included mouse traps and the use of hawks and falcons to scare off pigeons. And it also emerged laser pens were being used to try and scare off pigeosn - despite concerns the birds could be left blinded.
The cost was more than ten per cent more than the previous year, when £20,164 was spent on pest control.
There were 23 sightings of mice at Holyrood in 2015, while in 2011 there were only 11 reports.
A spokesman for the parliament said: “We have introduced some new pest monitoring methods as well as altering some of the existing methods for monitoring a wide range of pests, including rodents and insects. However, the amounts spent on pest control remain relatively small.”
