Cockroach-borne Health Hazards

cockroach control

Cockroach control is vital because these bugs bring filth and can be harmful. Indeed, their eating and nesting habits lead to the collection of harmful germs. Often, the health risks don’t consider the disgust we feel.

For businesses, this can affect both customer and staff health. Besides, it could result in a breach of food safety laws. It includes costs for cleaning and losing stocks—Steam ‘n’ Dry Cockroach Control Auckland Services guarantees quality pest control. Call us on 0800 783-266, or send us an email.

The Hazards Of Cockroaches

Pest Control Auckland Services warns that cockroaches can bring about adverse reactions, like high blood pressure and asthma attacks. It also goes along with other serious health risks.

The dead roach bodies, droppings, and saliva have proteins known to cause allergies. Indeed, most of all, it worsens asthma. Cockroaches opt for warm, damp areas with food sources. Therefore, removing those sites can help prevent roach infestations.

Cockroach Control And Asthma

Cockroach allergy was discovered in 1944 when patients developed a rash after roach skin contact. Indeed, cockroaches can trigger asthma because their body proteins are allergens.

Unlike those with asthma, others can also develop the condition. Almost 70,000 people in Auckland have asthma, and these pests are a massive cause of respiratory disease. Children are vulnerable to allergens, putting them at a higher risk of asthma. Also, people living in inner-city areas are at increased risk. It is, however, unclear whether cockroaches are the cause. Still, it is the reason for higher asthma rates in cities since they are more prevalent in urban areas. Steam ‘n’ Dry Pest Control Auckland Services can help when particles spread by the air. Consequently, removing these inhaled proteins leads to an asthma attack.

Other Diseases For Cockroach Control


Like rodents, cockroaches also transmit the Salmonella bacterium in salmonellosis. It is a disease in humans with symptoms similar to food poisoning. Cockroaches harbour the bacteria by feeding on contaminated food materials.

E. coli Infections

Escherichia coli is a commonly found bacterium in the human gut. Although most strains are harmless, some can cause severe food poisoning.

The common symptoms of an E. coli infection are watery diarrhoea and abdominal cramps. Similarly, uncommon ones include fever, chills, nausea, and muscle aches.

Indeed, symptoms usually last three weeks and need little to no medical support.

Typhoid Fever

Typhoid fever is a bacterial infection caused by Salmonella typhi and is highly infectious. Cockroaches gather this disease by faeces with the bacterium. Indeed, children and older people are at the most risk.

Typhoid fever symptoms encompass fever, headaches, and muscle aches and can also involve constipation, diarrhoea, fatigue, and stomach pain.

Indeed, you should seek medical attention if you have any of the symptoms. With treatment, this disease will quickly improve within three to five days. But if left untreated, serious complications can occur.


Cholera is an acute diarrhoeal infection. It is frequent in developing countries with inadequate sanitation. The condition occurs by ingestion of food with the bacterium. Cockroaches can spread through their faeces and vomit as contaminants if exposed to the bacterium.


Dysentery is a type of gastroenteritis that results in bloody diarrhoea. Generally, most people suffer from mild symptoms and recover without medical attention within a week.


Cockroach faeces, saliva, bodies, and casts can trigger allergic responses. Of course, these allergens can become airborne indoors. Thus, people who live in or visit infested dwellings may breathe the dust. People with these allergies may experience sinus congestion, rash, sore throat, and eye irritation. Many allergies follow a seasonal pattern; persistent symptoms could signal a severe infestation. Indeed, cockroach allergies can exacerbate asthma in specific individuals.

The Effects Of Cockroach Infestations

Cockroaches can spread these diseases through direct and indirect contact. These bugs crawl beneath appliances, counters, and corners around the area.

Other pathogenic bacteria they harbour include:

Staphylococcus aureus
It is a gram-positive cocci bacterium. This organism is generally harmless but can cause serious infections.

Like S. aureusStreptococcus infections come in various forms, from mild throat infections to life-threatening diseases.

Below Are a Few Ways to Keep Away From Cockroach Problems:

  • Never allow dirty dishes to hang around the sink overnight.
  • Keep food leftovers in the fridge or storage containers with tight lids.
  • Do carpet cleaning. Besides, other treatments can help.
  • Remove trash from home. Also, vacuum regularly.
  • Regularly check and clean the pan underneath the fridge.
  • Finally, seal off cracks to avoid pest entry points.
