Pest control in hospitals

The NHS spends approximately £100,000 each year on pest control in London alone. It’s a serious problem, and given the current coronavirus pandemic, hospitals and healthcare facilities are going to be stretched to capacity (and perhaps beyond). The last thing they need is to worry about a pest infestation. In this article, we outline the pests that pose the biggest threat to hospitals as well as some pest control measures that hospitals and healthcare facilities can take to protect themselves. 



Rats and mice can get into a building via the smallest gap in a wall or floorboard, and once they’re inside, they like to stay there. Rodents generally like to chew on things which can cause huge problems for the building and patients. Rats and mice will gnaw through wood, floorboards, and plaster on walls, weakening the structural integrity. They may also chew through electrical wires, which can affect hospital equipment and cause significant repair costs, not to mention the increased fire risk that comes with broken wires. 

As well as the physical damage that rodents can cause, they leave urine and droppings everywhere they go. They’ll be attracted to kitchen areas and pantries and may contaminate the hospital’s supply of food, which poses a health risk and an economic nightmare. 


Bed bugs

Bed bugs are arguably the biggest concern for hospitals; they spread very easily via clothing, bags and regular visitors, and you can have a large-scale infestation on your hands incredibly quickly. It can also be difficult to fully eliminate bed bugs from a logistical perspective. Hospitals and nursing homes are full of beds and furniture, and many patients will be unable to leave their beds for long enough to provide adequate pest control treatment. There isn’t a spare bed for every patient! 

Bed bugs are also incredibly problematic due to the fact that they live on beds – they cause physical and emotional discomfort for anyone who’s laying in a bed with bed bugs. Bed bugs bite and their bites can cause inflammation and itchiness – the last thing you want when you’re admitted to hospital. 



Cockroaches pose a significant threat to our health, and are therefore a huge problem for hospitals and healthcare facilities where people’s immune systems are vulnerable. Cockroaches carry a number of diseases, including salmonella and even typhoid, as well as parasites and bacteria. They’re also incredibly resilient and can survive in very hostile environments. 

Food is at risk of being contaminated, as are any operating theatres and areas which need to be sterile. Cockroaches aren’t particularly fussy when it comes to where they stay, they’ll colonise areas under sinks and toilets, kitchen units, food cupboards – virtually anywhere. 

Cockroaches may also be a sign that hygiene levels in a facility are subpar, as they tend to breed and flourish in sewers or damp areas. Not only are they a problem themselves, but they’re also symptomatic of a wider issue. 



This may be a surprising entry to this article, but birds (mostly pigeons) cause significant problems for hospitals – especially in London where there are estimated to be over a million pigeons. Specifically, it’s the droppings and feathers of birds which pose a threat. They carry a myriad of diseases and can even affect air quality in and around a hospital. 

Pigeons congregate near hospitals because they offer shelter, vantage points, plenty of roof space, and access to food dropped by visitors or thrown away by the hospital. Their large numbers mean that they produce a significant amount of droppings, which can lead to structural damage for buildings and vehicles – and it’s a serious eyesore. 



Flies are an obvious problem for hospitals. Being flying pests, they move around very easily and quickly, contaminating everything they come into contact with. From food to equipment to furniture, it’s hard to keep flies away from virtually anything. Flies are known to carry diseases such as salmonellosis, conjunctivitis, and tuberculosis, so appropriate pest control measures are paramount in healthcare centres. 


Pest control measures hospitals can take

There are a number of things that healthcare professionals can do to help to reduce the likelihood of a pest infestation developing. Of course, doctors, nurses, and carers are incredibly busy, so these are little, practical steps that can be taken. 


Tidy up

It may sound simple (almost patronising), but taking an extra couple of seconds to clean your table after eating lunch can go a long way. Simply sweeping up the crumbs and wiping up any spillages will make the area far less attractive to pests. Similarly, keep your food in a sealed container and make sure it’s stored appropriately – if something is meant to be refrigerated, then don’t leave it in a cupboard where it’s likely to expire quickly and attract pests. 

Also, don’t let rubbish pile up and bins spill over. Empty them as soon as they’re full – the less time rubbish spends lying around, the better. And ensure that all bins have lids, it’s an added barrier against pests. 


Control what comes in

It’s important to control what is entering your hospital or facility. Whoever is responsible for taking in food deliveries must inspect them and make sure they’re correctly packaged and aren’t harbouring any unwanted guests. By the same token, don’t leave any external doors open for long – keep them closed so that pests don’t simply wander in. Failing to do so is like willingly opening your front door at home for burglars.


Report bigger issues

These maintenance steps will go a long way to reducing your risk, but the biggest piece of advice we can give is to call a professional to fix certain structural problems that are likely to attract pests. For example, if you notice leaks or areas of damp, then call a plumber immediately. If you notice decaying wood inside or on the building’s exterior, or cracks and gaps forming in the walls and floorboards, then call someone to repair this immediately. As the saying goes, prevention is better than cure, and this rings true for pest control. 

If you suspect that you have a pest issue, i.e. by spotting droppings or evidence of some other activity, then call a pest controller immediately. It’s important to have the situation assessed and treated as soon as possible to minimise the extent of the infestation and the damage caused by pests.
