Rodent traps in the dining area of a disability home were just one of several areas of criticism outlined by HIQA in a damning report.
Two care homes run by St Patrick's Centre (Kilkenny) Ltd were found to have "major non-compliance" in the reports.
St Michael's Centre for people with disabilities and St Patrick's Children's Services - both located on the same campus - were visited by Health Information and Quality Authority (HIQA) inspectors in May.
In the case of both centres, HIQA raised concerns over management, fire safety, training and staffing. In each case management said that they would implement changes in order to meet HIQA standards.
The report found St Michael's centre was "unclean and poorly", with cobwebs and flooring disrepair, as well as it being under-resourced and understaffed.
It also noted that there were two rodent traps found in the dining room in one of two bungalows.
There were 21 residents and four vacancies in the centre at the time, the HIQA report said.
The report says that an "immediate action plan" was given to the provider to address the issues after the inspection.
Bosses at the centre responded to HIQA in the report, outlining that they are committed to implementing changes.
Management said it was committed to providing more staff in the St Michaels centre and said a full-time nursing position alongside 85 extra health care hours had been introduced.
The management also said it was undertaking a new approach to cleaning in the centre and that works were scheduled to make improvements to residents' bedrooms.
The second centre inspected, St Patrick's Children's Services, provides residential care for up to ten children with profound intellectual disabilities and autism between the ages of five and 18.
The HIQA report outlines "deficiencies" in the management of the centre, and says that children who needed psychological or occupational therapy assessment and treatment, "either did not receive this or were placed on a lengthy waiting list".
The management said it was in the middle of an assessment process to help establish how to solve the issue.
HIQA raised concerns over the lack of written evidence of a comprehensive assessment of each child's needs at the centre.
Management said it would now carry out an assessment of all new children prior to their entry, and "improve staff training" to achieve better communication with the children.
