Will it cause discomfort?


Hello, doctor.
I have noticed cockroaches appearing in the area where I hang clothes on the balcony.
I'm not sure if they can fly or if they have crawled onto the clothes.
If they did crawl onto the clothes and I wear them later, could it cause discomfort or a bacterial infection? Since there are small children in the house, I'm unsure if I should rewash all the clothes.
Thank you!

Hello: Cockroaches can carry many viruses and bacteria, and during their movement on clothing, they may also lay eggs or leave behind antennae, hairs, secretions, etc., which can lead to infections or allergic reactions.
Therefore, if there is any concern that clothing has been crawled on by cockroaches, it is advisable to wash, disinfect, and sun-dry the items again for safety.

More Info


Cockroaches are common household pests that can pose health risks, especially in homes with children. While the mere presence of cockroaches does not guarantee that they will cause health issues, their potential to carry pathogens and allergens makes it important to address any infestations promptly.

Cockroaches are known to carry a variety of bacteria, viruses, and parasites on their bodies and in their feces. They can contaminate food and surfaces, leading to foodborne illnesses. Some of the pathogens associated with cockroaches include Salmonella, E. coli, and various types of viruses. These microorganisms can cause gastrointestinal issues, which may lead to symptoms such as nausea, vomiting, diarrhea, and abdominal pain.

Additionally, cockroaches are known allergens. Their droppings, saliva, and body parts can trigger allergic reactions and asthma attacks, particularly in sensitive individuals, including children. Symptoms of cockroach allergies can include sneezing, runny or stuffy nose, itchy or watery eyes, and skin rashes. In more severe cases, exposure can exacerbate asthma symptoms, leading to difficulty breathing and wheezing.

If you suspect that cockroaches have come into contact with your clothing, it is advisable to take precautions. Washing the affected clothing in hot water with detergent can help eliminate any potential contaminants. High temperatures are effective in killing bacteria and other pathogens that may be present. If the clothing is delicate and cannot be washed in hot water, consider using a dryer on a high heat setting, as the heat can also help sanitize the fabric.

In addition to washing clothes, it is essential to address the underlying issue of cockroach infestation in your home. Here are some steps you can take to minimize health risks associated with cockroaches:
1. Clean Regularly: Keep your home clean and free of food debris. Regularly vacuum and wipe down surfaces to remove crumbs and spills that may attract cockroaches.

2. Seal Entry Points: Inspect your home for cracks and crevices where cockroaches can enter. Seal these entry points to prevent them from getting inside.

3. Store Food Properly: Keep food in airtight containers and avoid leaving pet food out overnight. This reduces the availability of food sources for cockroaches.

4. Reduce Clutter: Cockroaches thrive in cluttered environments. Reducing clutter can help eliminate hiding spots for these pests.

5. Use Pest Control: If you have a significant infestation, consider contacting a pest control professional. They can assess the situation and provide effective treatment options.

6. Monitor for Allergies: Keep an eye on any allergic reactions or respiratory issues in your family, especially in children. If symptoms arise, consult a healthcare professional for advice.

In conclusion, while cockroaches can pose health risks, taking proactive measures can help mitigate these risks. Regular cleaning, proper food storage, and addressing any infestations are key steps in protecting your family's health. If you have concerns about potential exposure or health effects, it is always a good idea to consult with a healthcare provider for personalized advice.
