Do Cockroaches on Clothes Cause Health Risks for My Family? - Family Medicine

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 lead to a bacterial infection? Since I have small children at home, I'm uncertain whether I should rewash all the clothes.
Thank you!

Hello: Cockroaches can carry numerous 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 suspicion that clothing has been crawled on by cockroaches, it is advisable to wash, disinfect, and sun-dry them again for safety.

More Info


Cockroaches are known to be carriers of various pathogens and allergens, which can pose health risks, especially in households with children or individuals with weakened immune systems. While the mere presence of cockroaches does not guarantee that they will cause health issues, their potential to contaminate surfaces and clothing is a concern.

When cockroaches crawl on clothing, they can leave behind feces, saliva, and body parts, which may contain bacteria and allergens. These contaminants can lead to various health problems, particularly respiratory issues, skin irritations, and gastrointestinal infections. Children, due to their developing immune systems and tendency to put their hands in their mouths, are particularly vulnerable to these risks.

If you suspect that cockroaches have come into contact with your clothing, it is advisable to take precautions. Here are some steps you can follow:
1. Wash the Affected Clothes: It is a good idea to wash any clothing that may have been in contact with cockroaches. Use hot water and a strong detergent to ensure that any potential contaminants are removed. This is especially important for items that your children will wear.

2. Clean the Area: Thoroughly clean the area where the cockroaches were seen. This includes vacuuming and wiping down surfaces to remove any droppings or debris. Make sure to dispose of the vacuum bag or empty the canister outside to prevent re-infestation.

3. Monitor for Allergic Reactions: After washing the clothes and cleaning the area, keep an eye on your family members, especially children, for any signs of allergic reactions or respiratory issues. Symptoms may include sneezing, coughing, or skin rashes.

4. Prevent Future Infestations: To minimize the risk of cockroaches returning, ensure that your home is clean and free of food debris. Seal any cracks or crevices where cockroaches might enter, and consider using traps or contacting pest control services if the problem persists.

5. Educate Your Family: Teach your children about hygiene practices, such as washing their hands after playing outside or handling clothing that may have been exposed to pests.

In summary, while the likelihood of immediate health issues from cockroaches on clothing may be low, it is prudent to take preventive measures to protect your family's health. Regular cleaning and monitoring for signs of pests can help maintain a safe and healthy living environment. If you have ongoing concerns about cockroach infestations or health risks, consulting with a healthcare professional or pest control expert may provide additional guidance tailored to your situation.
