7 Pests to Put on Your Watchlist in the Workplace

Did you like this post? Share it on ...

Pests are any animal, which has a harmful effect on humans, their food and living conditions.  Pests carry all kinds of germs and parasites.  Pests, humans and food are a bad combination.  Pests should not come in contact with food, food handling equipment and surfaces where food is prepared.

Two things can happen:

  1. The pest itself can end up in the food. Believe me, your customer will notice if they bite into something crunchy with legs.  This is very embarrassing for any company.
  2. The germs (bacteria and viruses) and parasites the pests carry might contaminate the food. This can lead to food poisoning and infections.

Pest control in the workplace, especially in a food handling environment is not an option but a requirement.  The proper pest control measurements will reduce and even eliminate the risk of food contamination caused by pests.

7 Pests You Might Find in the Workplace

1.  Flies

Flies in the Workplace

Did you know flies are one of the most dangerous pests you can find in a food-handling environment?  The World Health Organisation (WHO) estimates that the common housefly is capable of transmitting at least 65 diseases.

Flies are stubborn pests that can undermine your business’s image.  They are active during the day, very persistent, easily visible and do not try to hide.  They are literally in your customer’s face.  It is also difficult to get rid of these annoying pests once they find a way to enter a building.

2.  Rodents (Rats and Mice)

Second to flies, rodents also make the top of this list because they are one of the most dangerous pests you can find in a food-handling environment.  Rodents transport food-borne pathogens through saliva, urine and droppings.  Rodents also carry parasites like fleas and ticks.

Rodents are nocturnal (more active at night), shy and likes to hide.  It is more difficult to spot them.

3.  Cockroaches

Cockroaches in the workplace

As with most pests, cockroaches also like the same food humans consume.  Paper materials, paste, glue, wallpaper and drapes are also part of their diet.  Cockroaches are tough little critters and it is claimed they can withstand exposure to extreme levels of radiation.

Cockroaches often transport microorganisms on their bodies, as well as viruses and pathogens, which can cause various health hazards.

As with rodents, cockroaches are also nocturnal and like to hide.  Spotting them is more difficult.

4.  Other Crawling and Flying Insects

Other Crawling & Flying Insects

Be on the lookout for other flying and crawling insects.  The types of food you process and store, as well as the location of the facility, play a role in what type of other insects you might encounter in the workplace.

For example, you might find fruit flies and gnats in a fruit processing and handling environment, but not so much in an abattoir.  Although some species of gnats are bloodsuckers.

Identify other insects you notice and add them to your Pest Control checklist.

5.  Birds

Birds in the workplace

Birds are not pests in the normal sense, but when they enter the food processing and handling area, they become pests.  The most common birds you might find inside buildings, especially warehouses, are;

  • pigeons;
  • doves;
  • and sparrows.

In most cases, birds enter the facility by accident, but exposed beams near roofs are ideal for nesting.  Birds are larger than your normal pests and easily visible.  It is also much easier to control them.  They normally enter through open windows and doors.  Keeping these closed should solve the problem.

Birds like to do their business during flight and exposed food, food preparation surfaces and equipment could be in the way.  Birds carry parasites and the droppings and feathers may contain harmful germs and parasites.

6.  Bats

Bats in the workplace

You would not normally find bats inside your processing area, but they are famous for living and breeding in roofs (between the roof and ceiling).  From time to time one might lose its way and end up in your processing area.

Bats are not common pests, but they (including their droppings) do carry a variety of harmful germs and parasites.

7.  Domestic Animals

Domestic Animals

Domestic animals are not pests until they enter the food processing area.  Chances are very slim you will find domestic animals roaming around your food processing area, but it does happen.

For example, stray dogs and cats are always on the hunt for food and water.  Given a chance, they will enter a food processing area.


Pests carry germs and parasites.  Keep them out of your food processing, handling and storage areas.

  1. Thanks for such educating blog post. I own a restaurant and these pest have been a mojor problem I face most time. From damaging food substance to making my female employee run around. I get really upset seeing these things and I’ve been looking for ways to go about it. Thanks for introducing ASC consultants. How do I contact them? 

  2. I owe a big Thank You for this educating review on pest . they are frustrating and seem so hand to curb. This post has educated me accurately on the kinds of pest and how they pass across diseases to food,the danger  and reasons why they shouldn’t be given chances in our houses and food utensils. I must say a big thank you for this and I hope to see more review on how to curb them and deter them from our homes… This post has not only added value but has given a better idea of the risk in our houses which pest posses.

  3. Great post right here. Rodents and cockroaches are simply the worst possible on the pest list of mine. The rate at which they multiply is simply beyond imagination and at first, one might think it is only one but then, trust me, they have a battalion in stock already. I try all possible best to look out for them at all cost and to prevent them from having any form of contact with my food processing areas. I particularly do not know about birds being a pest too. Thanks for this.

  4. Flies, rodents and cockroaches. Oh God how I hate those intruders. You’re very right when you say pests are bad carriers of different parasites and bacteria that can be harmful when digested in the food we eat. Controlling them and staying away from this is very important. Normally at home I use pesticides but they seem not to be contained totally. I will definitely consult

  5. Hi Ascconsultants,

    Thanks for reminding us that every tiny pest in our workplace might cause huge troubles for our health. I used to work at a company that you could hear some mouses running above you when you try to keep calm not scream. I am glad that I left the company since there is no managers want to solve this issue.

    I wish I knew your blog earlier then I might request my company to contact you for a better solution. At least, we could try to do something together instead of nothing. I wonder do you provide a solution to workplace too, so I will keep your blog for future need?

    Can’t wait to read your reply,


  6. I never thought you would include dogs or other four-legged animals as pests in the food processing area but I agree with you.They could bring germs and bacteria on their feet and skin into the food processing area.

    Anyway, I like your services and the advice you give.I’ll bookmark your site when I need your help.

    • Hi Eli,
      Thanks for leaving a comment. You are more than welcome to contact us if you need any advice. You do not see cats and dogs that often in food processing areas, but it can happen.

      Have a great day!

  7. Rodents and cockroaches are at the top of my list. They breed like a photocopy machine. If you see one it is likely there are a lot more hiding somewhere. These pests can cause a lot of trouble and carry a lot of bacteria. Making your workplace a feeding and breeding ground. Waste management is important to keep these pests under control.

    • Hi Kit,
      Thanks for the comment. You are right, waste management is important to keep pests under control. It is important to have a proper waste disposal and management system in place. Pests are a no no in a food handling environment.

      Have a great day!
