More than 60,000 complaints about pest problems in council homes
Councils have dealt with more than a 'staggering' 60,000 cases of infestations.
Councils have dealt with more than a "staggering" 60,000 cases of infestations in local authority homes in the last three years.
Figures obtained by the Liberal Democrats using Freedom of Information showed councils received 21,365 complaints about pest problems in 2018.
That was up from 17,567 the previous year, and over the past three years a total of 61,168 complaints were received.
Tenants complained about issues with a range of pests, including woodlice, wasps, bats, beetles, cockroaches, slugs, mice, rats and moths.
Others contacted the council because of problems with seagulls, squirrels, pigeons and foxes affecting their property.
Liberal Democrat housing spokeswoman Caron Lindsay said while some cases of pests were "unavoidable", the Scottish Government needed to invest more cash in social housing.
She said: "The scale on which local authority tenants are reporting bed bugs, wasps, mice and other animals in their houses is staggering.
"It is completely unacceptable to house people in buildings that have cockroaches or other unhygienic infestations.
Imagine how awful it must be to feel that you can't let your baby play on the floor in case they pick up mouse droppings or some other nasty."
Ms Lindsay added: "Every person deserves a clean and comfortable home. Poor quality housing can take a huge toll on people's mental and physical health. If the SNP hadn't been slashing local authority budgets for years they would be better placed to provide that.
Elena Whitham, community well-being spokeswoman for the local government body Cosla, said: "Every home in Scotland will experience unwanted guests/pests on occasion.
"Scottish Councils spend a significant sum every year maintaining around 314,000 homes in urban and rural areas across the country.
"All local authorities will seek to remedy any issues arising from housing reports from tenants as quickly as possible."
Housing minister Kevin Stewart said: "We expect local authorities and registered social landlords to ensure their homes are kept in a good state of repair and are otherwise fit for human habitation. Local authorities can provide advice and assistance, and have powers under environmental protection legislation to tackle nuisances.
"The Scottish Government's target of delivering at least 50,000 affordable homes, including 35,000 for social rent, is on track to be delivered over this Parliament.
"The 2019-20 Scottish Budget also provides local government with an additional £298.5m revenue funding, a real terms increase of 1.2% for day-to-day services."
