  • Leprosy. Cockroaches are suspected as carriers of the bacillus Mycobacterium leprae, which causes leprosy.
  • Plague. It is widely believed that the bubonic plague is a rodent-borne disease, but cockroaches are also suspected to be carriers of the Yersinia pestis bacterium, which causes the plague.
  • Listeriosis. It is a serious infection caused by the bacterium Listeria monocytogenes. It is transmitted by consuming contaminated food and drink.
  • E. coli infections. Most strains of the E. coli bacteria are harmless, but some can cause serious food poisoning.

Diseases from rodents

  • Like termites, rodents not only cause significant property damage, they can cause many diseases, which include:
  • Hantavirus. Hantavirus Pulmonary Syndrome is caused by exposure to the faeces or urine of deer mice.
  • Leptospirosis. It is caused by a bacteria called Leptospira, which can infect both humans and animals.
  • Plague. It is a serious infection caused by a germ called Yersinia pestis. It can be treated with antibiotics.

Diseases Caused by Ants

  • The health risks posed by ants are not as significant as that of mosquitoes or rodents. However, they carry bacterial and fungal organisms that can cause serious diseases.
  • Bites and stings. While not a disease, ant bites and stings can cause serious symptoms and health problems brought about by allergic reactions and hypersensitivity to ant venom.
  • Food-borne diseases. Ants are known to contaminate food with disease-causing pathogens such as E. coli, Shigella and Salmonella.

Diseases Caused by Mosquitoes

  • Mosquitoes bite on the skin of humans and animals to feed on their blood. Their bite can cause many different diseases, some of them fatal.
  • Barmah Forest virus. It is a virus transmitted from animals to humans. It is common throughout Australia, particularly around inland waterways and coastal regions.
  • Chikungunya virus. It is transmitted through the bite of an infected female Aedes mosquito, which is also the virus responsible for dengue, yellow fever and Zika virus.
  • Dengue fever. Similar to a serious cause of the flu, dengue fever is common in tropical and sub-tropical countries like Asia, Africa and South America. In Australia, dengue fever occurs in North Queensland every year when a person gets infected overseas, then a mosquito bites that person, and that mosquito transmit the virus to others.
  • Malaria. It is an infection of the red blood cells and can be fatal if not given proper medical attention immediately.
  • Ross River virus. It is found all over Australia, but more common in Queensland, Northern Territory and the Kimberley region of Western Australia between January and April, particularly following heavy rains.
  • Zika virus. It is transmitted through the species of mosquitoes that also carry the virus for dengue fever and yellow fever. It can also be transmitted through sexual contact.

1. Eliminate moisture in the areas around your home.

Most pests tend to hang around areas with moisture. This is why it is important to keep the areas in your home dry at all times. Some pests that are attracted to moisture are termites, mosquitoes and silverfish. These pests will usually be found in moist areas such as bathrooms, kitchens, attics, basements, etc.

Observe proper hygiene at all times. Make sure all the places where your family gathers often are always clean. You can do this through basic tasks like keeping the garbage lid closed and disposing trash properly. If you’re putting away leftover food in the refrigerator, put them in a container with a lid.

In addition, always keep your resting areas clean. Regularly air your mattresses and pillows outside your home to get rid of pests in it like bugs, dust mites, etc. Let in air in your room, so fresh air can circulate around the house.

It is also important to be aware of the luggage, second-hand objects and containers that you let into your home as they may contain bugs, which can become a problem when infestation occurs.

3. Use insecticides.

The use of insecticides is the first line of defence against pests. They are effective in getting rid of pests and keeping them away.

How Can You Use Pesticides Safely and Correctly?

Pesticides are used around the home to control pests and weeds. They are generally safe and effective. However, pesticides must be used with caution because they have harmful ingredients that can enter the body through inhalation or ingestion by the skin and eyes.

Here are some tips on the proper use of pesticides around the home:

Read the label.

The first thing you have to do before using pesticides is to check the manufacturer’s warnings and recommended uses from their label. Only use the product according to what is specified in the label, nothing else.

Store pesticides properly.

Storing pesticides improperly can lead to leaks or spills. Check the label to learn if there are special requirements before using. Because pesticides that spill into the soil pose health risks, make sure any spill is dealt with immediately.

Call for professional assistance, if needed. Similarly, if your pesticides are past their expiration date, take them to the appropriate facility for disposal.

Keep pesticides away from children and pests.

If you’re spraying inside or outside, the first thing you need to do is make sure children and pets are far away from the area where you will be working. They are more vulnerable to the hazards of pesticides compared to adults. If toys get exposed to pesticides, it’s best to no longer use them.

Always be mindful of your containers.

Pesticide containers should always be closed when not in use. This is because a child may come across it and be exposed to its contents.

Here are a few safety practices to follow: if you’re transferring pesticide into a sprayer, make sure to close and store the original container before proceeding with spraying indoors or outdoors; and never move pesticides to an unlabelled container for storage.

More importantly, only use pesticides according to what is specified in their label.

Diseases caused by pests are preventable. They key is keeping pests away from your home by keeping it hygienic and making it unappealing to them. This means maintaining a space that doesn’t allow pests to thrive.
