Failure to Maintain Effective Pest Control and Sanitary Conditions Resulting in Widespread Gnat Infestation
Summary
The facility failed to maintain an effective pest control program to keep the building free of insects and other pests, resulting in a widespread gnat infestation throughout the building. Surveyor observations over two days identified gnats in multiple common areas, including the conference room, resident halls, laundry room, medication cart trash can, and dirty utility room. In the laundry room, gnats were seen emerging from the washing machine discharge drain, and in the dirty utility room, gnats were concentrated around a mop bucket containing stagnant, foul-smelling water. On a resident hall, multiple gnats were observed flying around residents and on surfaces throughout the corridor. Extensive observations in the kitchen revealed multiple environmental and sanitation issues that contributed to the gnat activity. Behind and around the ice machine and juice cart, there was wet dust, dirt, and organic debris such as food crumbs, sugar packets, and trash items, all saturated with moisture. Cracked, loose, and broken floor tiles near the ice machine drain and in the dish room contained food debris lodged within and beneath the damaged tiles, with standing water collected beneath the tiles and pooled around the ice machine drain. Standing water was also observed in the spray room, dish room, along walls, and in corners, with water spread across the kitchen floor after staff used a hose-mounted sprayer to clean the floors. On a subsequent day, the kitchen floor again had visible standing water, and a floor drain contained accumulated debris, paper fragments, and organic material, with a broken drain grate that did not fully cover the drain and exposed additional trapped debris; gnats were present in and near this drain and throughout the kitchen. Review of facility work orders showed only one report of gnats in common areas and nursing units for one month and one report of bugs facility-wide in the following month, despite the widespread activity observed. Service reports from the contracted pest control company over several months documented ongoing, unresolved environmental concerns in the kitchen and adjacent areas, including repeated findings of drain debris, standing water in kitchen and dishwashing areas, debris accumulation, and moisture issues that remained uncorrected by the facility. The pest control representative and pest control account manager both stated that gnats were originating from drains, cracks, and crevices with organic debris and moisture, and that routine cleaning practices were ineffective when debris remained or was pushed into cracks and around drains. They reported that recommendations such as debris removal, proper drain maintenance, and cleaning of hard-to-reach areas were repeatedly communicated and documented, but the facility’s compliance with these recommendations was inconsistent, with many action items left undone and carried over on subsequent service reports. Interviews with staff and leadership further described the facility’s actions and inactions related to pest control and sanitation. The Dietary Manager reported ongoing gnat concerns for multiple weeks, stated that pest control services were provided twice monthly, and that kitchen staff performed routine cleaning weekly and as needed, using a hose-mounted spray system for floors and pouring vinegar down drains between pest control visits. The pest control representative stated that pouring vinegar down drains would not eliminate the infestation and might attract gnats, as it did not remove organic buildup or kill larvae. The pest control account manager identified contributing factors such as debris buildup in cracks and flooring, lack of routine cleaning behind equipment, standing water or improperly maintained mop buckets, inconsistent cleaning practices in non-visible areas, and lack of routine maintenance of drains and traps, and noted that environmental cleaning often improved only after issues became more apparent. The VPO acknowledged gnat activity throughout the building and that pest control reports had identified ongoing debris concerns in the kitchen, but could not clearly describe a process to ensure consistent cleaning of hard-to-reach areas or to verify cleaning effectiveness. The DON and Administrator described expectations for reporting pests, emptying mop buckets, removing trash from medication carts, removing debris before floor cleaning, and not sweeping debris into drains, but these expectations were not reflected in the observed conditions. Two cognitively impaired and intact residents reported that gnats were always present, especially around meal times and food, and that they found them bothersome and undesirable during meals.
