The most common pests in your restaurant kitchen

Where there are food and water, and easy access to them, there will be pests. Crawling, flying, running, hiding, lurking…

Here are the most common pests in restaurant kitchens and other commercial establishments:

Mice and rats

Rodents, more specifically, rats and mice are also common pests in all food establishments. Restaurants, food manufacturers, hotels, cafes, pubs, etc. They can get inside the kitchen in a number of ways – through drains and sewers, through holes and cracks in walls or the basement.

Rats and mice can transmit diseases such as Leptospirosis, Toxoplasmosis, Salmonella, even Lyme disease, Hantavirus, and rat-bite fever.

Additional dangers of having rodents in your restaurant are property damage, contamination, additional pest infestation – fleas, ticks, mites. Contamination of the premises with their urine and droppings is also a problem. They can gnaw electrical cords and cause problems for appliances.

Cockroaches are one of the most common pests in commercial kitchens. They breed rapidly, can enter from various tiny holes, and they can feed on pretty much everything there is in a kitchen. 

They are nocturnal animals and you may not notice them for a long time until it’s too late and there are hundreds of them. In the daytime, they hide in the smallest places and in drains, under or behind appliances. This makes them hard to reach and get rid of. Furthermore, cockroaches climb on anything. They may crawl on your grill, cutlery, dishes, etc, which makes them unsanitary to use. 

Cockroaches can also be responsible for transmitting diseases in your restaurant, including E.coli, Listeria, Salmonella, Staphylococcus, and viruses.

These insects are a great nuisance not only for the kitchen but for the entire commercial property. It is unpleasant and unprofessional to have flies flying around your restaurant and land on people, their food, and cutlery while they are having a meal. 

Some flies species are considered a pest in the food industry: fruit flies, house flies, drain flies.

The main problems with flies are that they carry and transmit pathogens that can cause diseases such as E.coli, Salmonella, Cryptosporidium, Campylobacter, parasitic worms, and others.

Furthermore, in a commercial kitchen where the food and living conditions are good, flies can breed rapidly.

You’ll find them in cereals, grains, flour, seeds, nuts, dried fruit, spices, even pasta.

Signs of pests in restaurant kitchen

Regardless if you’re a restaurant, a cafe, or a pub owner, restaurant pest control must be your top priority. There are strict food regulations in the UK and infringing them can have serious consequences for your business. 

Pests like rodents and cockroaches are usually hiding from people. You won’t see any of them come out during the day while the kitchen is filled to the brim with people, to steal some of your food. But pests like flies and ants do not do that. If they infest your kitchen, you will see them all. 

Here are the signs of cockroaches and rodents to look for, if you spot any of the below mentioned, take adequate measures as soon as possible:

Signs of rats and mice

  • Droppings – dark brown (rats) or black (mice), elongated. Rat’s faeces are bigger than a mouse’s. 
  • Squeaking and scratching noises.
  • Damage to items in the kitchen – garbage bins, food storages, cardboard boxes.
  • Greasy marks/footprints – these animals are filthy and you may see the traces of their visit in the dirt and grease they leave in their way.

Signs of cockroaches

  • Droppings – they can have two forms – round, or oblong (depending on the species) firm faeces that are either dark brown or black. Or they can be runny and appear as smear marks.

  • Shed skin – this is something cockroaches do several times in their lifespan. If you see something that looks like a cockroach-shaped piece of skin, even just one, then you have an infestation.

  • Dead or alive cockroaches – the surest sign of an infestation is seeing the pest either live or dead. Be it a dead or alive cockroach, there are more where it came from, for sure.

  • Unpleasant odour – this is common for heavier infestations. If you’re sensing a weird, unpleasant smell and aren’t sure where it’s coming from, you may have a large infestation.

5 main factors that contribute to restaurant kitchen pest infestations

Regardless of the type of pest, they all come looking for the same things – food, shelter, water, a place to nest.

  • Food – in the food industry pests will always be a problem. Pests attack your stored food, already made food, and the garbage as well. As a commercial kitchen, there are items from all food groups, attracting various pests.
  • Water – having places with standing water in the kitchen. It can be a leaking faucet, a puddle left from a wet item, or from cleaning the kitchen counter or floor, etc. Even leaking pipes that are hidden from your sight can attract pests.
  • Shelter – if there is easy access to your kitchen and attractive hiding places, you can bet the pests will stay. A cluttered kitchen, or any premise in general, provide for more hiding spots where pests can hide and nest.
  • Cleanliness – if your kitchen isn’t well maintained, cleaned well daily, the garbage isn’t thrown out regularly, etc. pests will come lurking. This isn’t only about the kitchen but the dining room of your restaurant as well. It, too, should be cleaned well daily. 
  • Easy access – if there’s nothing stopping them, they will come without any hesitation. Too many doors, no door or window screens, cracks in walls, open windows, etc. are ways that pests can enter easily. 

There are many food laws and regulations that you must be aware of. Anyone who sees a pest in your restaurant can report the local authorities. Making sure you offer good and safe food to your customers should be the number one priority.

That can be achieved not only by hiring the best chefs and buying quality products but with regular checks on the food’s condition. Also with regular pest inspection, control, and preventive measures. 

How to clean a restaurant kitchen after restaurant pest control treatment?

Every pest treatment is unique depending on the property type and size, the type of pest, and the level of infestation. If you choose to hire a professional pest control company for your business, they will advise you to clean the property before the exterminators arrive on-site.
