The biennial poll of landlords reveals that Brits have a penchant for "marital aids" (of all shapes, sizes and colours), 1970s pornographic magazines, raunchy underwear, bondage equipment and blow-up sex dolls!
Animals, both dead and alive, also scored highly on the list. Tenants left behind a stuffed parrot, guinea pigs, a large dead fish in a recycling bin and even a snake living under the floorboards.
Kevin Firth, Director of The DPS said: "Cleaning up after tenants is often a big job for landlords but this research shows that it’s not always just dirt and mess they have to contend with.
"One landlord told us that a former tenant, a postman, had left behind bags of unopened mail in the attic. Another told us that he found a batch of winning lottery scratch cards in the property, while another said that he had been showing a prospective tenant around the property and found a complete stranger asleep in the bedroom!”
As well as sex toys and animals, other bizarre items left behind included: the engine from a lorry, a phallic shaped multi coloured door draft excluder, an inflatable Father Christmas and half a dozen milk crates.
Firth said: "We would encourage all tenants at the end of their tenancy to tidy the property appropriately and only leave behind items that were on the original inventory. This will help ensure that their deposit is returned in full.
"As the only custodial deposit protection scheme accredited by the Government, we are here to protect both landlords and tenants. In the event of a problem at the end of a tenancy our free and independent resolution service can be a good way of settling a dispute without the need to go to court."
