Question

To ask the hon. Member for Broxbourne, representing the House of Commons Commission, how many moth infestations were reported to parliamentary authorities in each year since 2021.

The number of moth infestations reported in each of the last three years is as follows:

2021 – 27
2022 – 44
2023 – 61

All moth related monitoring and required subsequent treatments are included in the annual contract fee with our pest control expert. This is inclusive of any number of visits, monitoring devices, additional treatments, preventative maintenance visits or reactive responses that may be needed to treat a problem. As such, no additional costs are incurred.

It is not possible to calculate how many devices have been installed in each of the last three years. However, a total of 982 monitoring devices have been installed during a permanent moth prevention programme which has been running since 2008.

The current number of devices installed is 751. This current count is subject to constant fluctuation.
