Two brothers who set up an illegal dump were found with 120 tonnes of rubbish in their garden.
Raymond Murray, 61, and Ian Murray, 54, were also found to have 500 rats at their home as a result of their business in Kinmel Bay, Conwy.
On Tuesday, Caernarfon Crown Court heard the infestation had caused a ”real risk to health” to neighbours.
A nearby caravan park also found dead rats in its awnings and live rodents running around the children’s play area.
The play area had to be closed and disinfected and refunds were given to customers.
During an earlier hearing, it was heard the brothers began a waste collecting business when they lost a taxi business and ran into financial difficulties.
After it was found to be uneconomical to take the rubbish to the tip, the pair began sorting it out at their home and the situation grew ”out of hand.”
When officers visited the home in May, hundreds of bin bags of domestic waste were found in the garden, including mattresses, furniture, car parts and a caravan.
There was also evidence of rat burrows and bin bags ripped open by the rodents.
In a £59,000 clean-up operation, more than 123 tonnes were removed from their home in Gwellyn Avenue. Between 400 and 500 rats were also killed using 156 rat traps – the average amount used across the country in a month.
In January, both brothers were handed 10-month prison sentences suspended for two years after pleading guilty to acting without an environment permit.
On Tuesday, it was found that the brothers had made £72,637 from their illegal business.
During the Proceeds of Crime Act hearing, Natural Resources Wales prosecutor Christopher Stables said the amount available for confiscation totalled £37,153 from Raymond Murray and £30,413 from his brother.
Mr Stables also asked the cost of the clean-up operation to be repaid. Judge Niclas Parry ordered the defendants to pay £67,566 within three months or serve 12 months in prison.
He also told the pair to place their house for sale within a week to cover the shortfall.
