Health Risks Associated with Cockroach Infestations

January 23, 2023

No one wants to live in a home or office space overrun with pests. Unfortunately, cockroaches can be especially insidious, spreading disease and disease-causing bacteria across the environment while they scavenge for food. Not only do these uninvited guests consume your food, but they also put you at risk of developing serious health issues when their populations grow too large to control. In this blog post, we'll discuss the potential health risks associated with cockroach infestations and how to prevent and treat them if they occur on your property.

What are the health risks associated with cockroach infestations?

Cockroaches species like German cockroaches which are the most familiar cockroach species can transmit several diseases, such as salmonella, E. coli, and typhoid fever. Cockroaches are also fond of nibbling on food packaging and containers, which can cause further contamination and food poisoning. Their ability to contaminate our food in many ways makes them especially dangerous to our health and well-being. For example, cockroaches excrete droppings that contaminate food with harmful bacteria and transport dangerous parasites. They also crawl all over counters, cupboards, and other food-preparation surfaces, leaving fecal deposits full of bacteria.

Furthermore, their saliva and feces contain allergens that can trigger asthma, allergic reactions, and other respiratory issues. Cockroach allergens are made up of proteins that cockroaches release through their bodies, saliva, and fecal matter. The proteins in cockroach allergens can attach to dust particles, making them easier to contact and aerate throughout a home. Exposure to cockroach allergens can aggravate asthma symptoms, life-threatening respiratory distress, itchy eyes, skin irritation, coughing, and sneezing. Therefore, individuals with cockroach allergies should take measures to keep cockroaches out of their homes by practicing good hygiene and sealing any gaps or crevices where they may be able to enter.

Signs of Cockroach Infestations

Cockroaches are unnerving pests that, unfortunately, can be found in many homes. To stop cockroach infestations from becoming severe, it is important to be aware of the signs and take action as soon as possible. Watch for cockroach droppings that look like dark specks that resemble small pepper grains or blackish-brown smears. You might also notice an unpleasant smell in infested areas, cockroaches scurrying about at night, or other cockroach debris like egg cases or molted exoskeletons. If any of these indicate cockroaches have been disturbing your home, contact a pest control professional for assistance in developing a plan to eliminate them.

How do I prevent and treat cockroach infestations?

Although the risks associated with cockroaches can be serious, it's important to remember that prevention is the best way to keep them away. The best way to prevent a cockroach infestation is to know what attracts them or makes them inside in the first place.

Cockroaches are attracted to food, water, and warmth. To prevent cockroaches from entering your home or office space, regularly vacuum and dust areas where they may enter to eliminate potential food sources. Make sure that all food products are stored in sealed containers and that all counters and surfaces are wiped down regularly. Additionally, look for potential access points, such as cracks in walls or windowsills, and seal them if you find them.

Sometimes, cockroaches can be from the outside through your things, such as when you move or bring items home from the outside. So, check all items carefully before bringing them into your home or office to ensure they do not contain any cockroaches.

Make sure to clean or eliminate boxes or piles of papers and clutter, as these can be great spots for cockroaches to hide. Additionally, ensure all plumbing lines are in good condition, as they can easily become breeding grounds for cockroaches.

If an infestation does occur, over-the-counter insecticides can help to contain the problem. These products typically come in sprays or baits, which you can use to target specific areas or cockroaches. However, if the infestation is particularly severe, it may be necessary to enlist the help of a pest control professional. Professional exterminators have access to more powerful treatments that can get rid of an entire population quickly and safely.


Cockroaches can be dangerous in any home or office, posing serious health risks. Fortunately, by practicing good hygiene and taking preventative steps to keep them away, you can protect yourself from the hazards associated with cockroach infestations. If an infestation does occur, there are several treatments available that can help to eliminate the problem. Taking action to control cockroach populations is the best way to ensure a safe and healthy environment.
