Pests & Disease In Your Home

Pests associated with the transmission of diseases to humans include  rodents ,  insects , and birds.

Some pests are more critical than others concerning disease. For this reason, we shall quickly separate pests into three groups:

Sometimes an overlap occurs, but for simplicity, we must focus on those we know are injurious to human health.

Pests we know to be injurious to human health may bite and sting but won’t always carry disease. More concerning is a pest’s capacity to transmit disease-causing germs!

 Pests pick up harmful microorganisms on their bodies and inside their bodies as they feed and forage. When these pests enter our homes, they inevitably deposit pathogens.

Pathogens are “disease-causing” germs that include bacteria and viruses. Pests often deposit these on surfaces and unprotected foods.

Insects that bite, like mosquitoes, fleas and bed bugs, sometimes cause severe reactions in the skin. Insect bites also contaminate the blood and body, turning the human host into a carrier or reservoir of disease.

Eliminate cross-contamination from pests by completing pest exclusion, control, monitoring, housekeeping and maintenance.

Although your chances of severe infection are minimal, people die from exposure to pest-borne diseases in the UK every year.

The likelihood of disease transmission increases with exposure to a specific microorganism, route of infection and the health and disease resistance of the individual in question.

Immunosuppressed people are likely to suffer the catastrophic consequences of the disease. These people are termed “susceptible hosts” susceptible because they are:

We describe how people become infected as “Mode of transmission”. I’m sure you think this is common sense, and it is, but let’s delve deeper and glance at the types of transmission.

Contact transmission is the most common form of transmission, divided into four categories.

Direct contact  – this might be where you touch a pool of rat urine.

Indirect contact  – this might be where you touch a pen (or another object) that became contaminated with rat urine on it.

Droplet transmission  – Not relevant to pests, but refers to respiratory secretions coughed or sneezed into the air near you.

Airborne transmission  – As rodent, bird and insect faeces begin to dry, they break down into particles that easily become airborne. These particles contain viruses, bacteria, and fungi that can cause respiratory and systemic disease.

Yes and No!

Let’s make things simple! A hazard (e.g., bacteria) is something that can do you harm, and the risk is the likelihood the hazard (e.g., bacteria) will do you harm. So this all comes down to exposure.

The greater the exposure, the greater the likelihood of significant illness.

As an example, lots of rats mean lots of urine, lots of faeces and lots of damage to wiring, plastic pipes, etc.

The infective dose of any microorganism, like bacteria and viruses, is vital to consider. The infective dose of any microorganism is simply an estimate of how many microbes of a given species it takes to make you sick.

Imagine a virus so small it can infect bacteria! Exposure to just a few of these will support the development (incubation) of the illness it manifests.

In the case of bacteria , an infective dose will require the ingestion of hundreds of bacteria to cause sickness.

The more exposure you have to a disease-causing microorganism or pathogen, the more likely you will get sick.

Prevention is always better than a cure. Get rid of the hazard, and the risk no longer exists – simple!

Protection of your immediate environment (occupied or living spaces) is paramount.

Prioritise professional help and guidance

If you are struggling with a low budget, you should still get a professional inspection. Select pest professionals prepared to offer advice for DIY control based on their findings.

Damage and contamination are cumulative. Avoiding this step could mean you waste time and money doing things the wrong way.

Once you identify the source of an infestation, you better understand what you’re up against. Every pest has a source of infestation, and finding it will be a game-changer for you.

Elimination is rarely possible without knowing where the pests have originated.

Sometimes achieving control and elimination is simple! Filling a suspect hole on the outside of your home is a common example of controlling mice.

The faster extermination occurs, the sooner you are out of any potential danger from ongoing microbial re-contamination.

Consider storing food products in robust storage boxes. Most food packaging offers little defence against pest infestation, especially from rodents. Discard all contaminated items.

Antibacterial wipes can be a cheap and effective means of eliminating pathogenic microbes from food prep surfaces. You can never be too clean!

Outside the box thinking always helps. Consider protecting other essential items and surfaces like toothbrushes, tabletops, and cooking utensils.

Rodents routinely contaminate crockery stored on low-level shelving with rodent urine and faeces. If rodents can access kitchen cabinets, consider extra precautions for their use.
