Do Cockroaches Bite?

Cockroaches are one of the most ubiquitous and resilient household pests. They have caused a unique fear in the humans who encounter them for a long time.

Perhaps it’s their well-known love of unsanitary environments. Maybe it’s the way they scuttle around. It may even be the knowledge that eliminating a cockroach population can be a significant challenge. Whatever the case may be, the sight of just one of these nocturnal nuisances is enough to frighten anyone… because where there’s one cockroach, there are usually more.

In fact, an estimated 78 to 98% of homes in urban areas play host to cockroaches. Often, the homeowners won’t even know they’re there.

Cockroaches are both nocturnal and shy, so even a large population can slip by undetected. They also tend to live in places where humans rarely go, hiding in cracks and crevices, garbage bins, drains, or even inside appliances.

As omnivorous creatures, they have a variety of food sources to choose from. Some of these are quite morbid, like dead skin, dried blood, feces, and even other roaches. But they typically prefer to eat the sweet and starchy foods found in human kitchens or in the trash. 

Cockroaches are considered repugnant for good reason. They can carry diseases and bacterias, such as E. coli and salmonella. They can help spread other infections, such as diarrhea, cholera, dysentery, leprosy, and typhoid fever.

The presence of cockroaches can make asthma and other allergies worse. Certain proteins that cockroaches produce can occasionally cause severe reactions in allergy-prone people.

It’s unlikely for cockroaches to be the direct cause behind a disease spreading, though. They serve more of an ancillary facilitator role.

Do Cockroaches Bite?

Their role as a potential disease carrier does pose a direct threat to human health in the event of a sustained cockroach bite.

Although it’s rare, cockroaches have been known to bite humans. They’re more likely to feed on dead things than living. If they do feed on the living, they’ll generally prefer snacking on dead skin, nails, or hair.

The main places that cockroaches bite are the face, hands, mouth, and fingers. This could be because these locations are more likely to contain residual traces of food.

Although it depends on individual pain tolerance, it’s rare for roach bites to be significantly painful. They’re often described as causing a brief twinge of pain that lasts only a few seconds.

Despite the transient pain, roach bites are actually quite powerful. One study found that cockroaches bite with a force greater than 50 times their own body weight, which is about 5 times stronger than the human jaw.

It’s common for a 1–4 mm red spot to appear after a roach bite, similar in size and appearance to those caused by mosquito bites. These spots will often be itchy and you may develop a rash. Individuals that are allergic to cockroaches may have a stronger reaction, including swelling, a more significant rash, or a larger raised red area.

Although these bites are similar in appearance to bed bug bites, it’s possible to differentiate the two. Roach bites typically stand-alone while bed bug bites are usually found in clusters or in straight lines.

How to Treat Roach Bites

If a cockroach bites you, the best way to treat it is to use the methods that are commonly used for other benign insect bites.

The best advice is to avoid scratching the bite, as this could further aggravate the skin and make you more vulnerable to infection.

Other things you can do:

  • Apply an ice pack to the bite for 15 to 20 minutes a few times a day.
  • Keep the area elevated to minimize swelling.
  • Use either a homeopathic lavender-based cream or a hydrocortisone cream. Make sure you consult your doctor before applying any medicated cream on your skin, though.

If a cockroach bites a child or a baby, you should treat them just as you would an adult.

Pay attention to any reaction the baby may have since they’re unable to verbalize their symptoms. They may also be more prone to picking or scratching, which can make their symptoms worse. If the redness or rash lasts longer than a few days, it may be time to consult a doctor.

The immune systems of children are often not as robust as adults, so the doctor may decide to use more drastic treatment measures.

Cockroach Bite Prevention

The best way to prevent future roach bites is to assess the level of infestation that you’re dealing with. Calling a pest removal company is a crucial first step in eliminating your cockroach problem

In the meantime, maintaining good home hygiene is always helpful. This will reduce the number of places where roaches can live and breed

To prevent cockroach infestations, it’s often essential to:

  • Sweep and vacuum regularly. 
  • Do the dishes immediately after meals. 
  • Scrub your countertops. 
  • Seal any gaps or cracks in your home’s foundation and infrastructure. 
  • Remove any standing water or leaking pipes.

Cockroaches can appear to be a formidable enemy. But you should take comfort in knowing that although they may be gross, they’ll rarely cause you direct harm. Implementing basic cleaning measures, being aware, and reaching out to reputable pest companies when necessary will ensure that you stay safe from cockroaches!
