A pregnant mum was outraged after spotting a mouse running around Croydon University Hospital earlier this week.
On Wednesday, Kirsty Groves was taken to Croydon University Hospital with a serious throat infection.
The 19-year-old is three weeks away from giving birth to her second child, reports My London.
She is currently in a private room in the maternity triage unit. In the corner of her hospital room, a "big mouse " was spotted scurrying about.
Kirsty's 21-year-old Anton Cundall filmed a mouse and sent it to her mum Louisa Groves.
The Croydon hospital said it has a dedicated pest control team which deal with reported incidents.
42-year-old Louisa and her daughter are now concerned about returning to hospital to have her body.
She said: "This is worrying her. Now she's seen this does she really want to go back to Croydon? It is going to put her off going back to hospital.
"She mentioned it to the staff and they didn't seem bothered about it at all.
"They sent me the video of it running around and you can hear how scared she is.
"I feel disgusted, it needs to be more hygienic. Pregnant women shouldn't have to experience or see that."
It is not the first time rodents have been spotted in the London Road hospital.
In February another young woman said she was "traumatised" after spotting a mouse running around a ward.
A spokesperson for Croydon Health Services NHS Trust said: "We would like to apologise to Miss Groves for her experience. We have strict procedures in place to ensure that high standards of cleanliness are maintained on our wards, including regular deep cleans and dedicated pest control services, who deal with any reported incidents promptly and ensure every precaution is undertaken to prevent access".
Several years ago, staff and patients were left disgusted after a swarm of mice shut down a maternity ward.
Postnatal patients at Maple Ward in Heartlands Hospital, Birmingham, had to be moved from their beds to make way for the pest control team.
And it was not the first time the hospital trust experienced problems.
Heartland's NHS Trust says it spent a whopping £106,390 from 2009 for five years on pest control.
During that time there were a staggering 717 reports of pests. This includes midges and cockroaches.
On October 4, 2012, a rat was reported in the discharge lounge and on the following day a dead rat was reported in the same area.
And while bosses at the hospital claimed the building had been "mouse free" for over 24 hours, patients were still concerned.
