How to Prevent Pest-Related Health Hazards with Gutter Mesh

How to Prevent Pest-Related Health Hazards with Gutter Mesh

by | Jul 26, 2022 | Keeping Out Pests

It’s never pleasant to discover that you have unwanted animal residents in or around your roof and gutters – and for good reason.

Pests can pose a significant threat to you and your home, causing extensive damage, making a mess and destroying your peace and quiet.

But one of the most serious consequences of pests in your gutters and roof is the health hazards they can create.

Contamination & disease 

Many pests are prolific disease carriers, and like almost every other creature on the planet, they urinate, defecate and die.

But while this mightn’t be much of a problem in the great outdoors, it can cause all sorts of problems around your home.

Rats are the most famous disease carriers, but possums, birds and other pests are also guilty. The droppings, urine and carcasses left behind by these pests can contaminate your home, causing sickness, exacerbating allergies and asthma, and spreading further disease. Dead animals in your gutters can also contaminate the water in your rain harvesting system or cause other health problems by clogging your gutters.

Parasites & extra pests 

To complicate the problem further, most home invading pests don’t come alone.

Fleas, mites, ticks, lice, worms and other tiny pests and parasites often accompany birds, possums and other animals into your gutters, roof and home. Once there, these tiny pests may seek human hosts or spread to your pets.

Bites from smaller pests can cause serious irritation and dermatitis, or even trigger allergic reactions and asthma for both pets and people. Because they’re so small, these insects can also be some of the most difficult pests to effectively remove, making them a serious threat to the health of your home.

Snakes 

Snakes often make their way into gutters and roof cavities in search of prey or a warm place to sleep and breed.

But while a snake in your roof might conceivably help control the presence of other pests, snakes are obviously not great for the health of your family or pets.

Snake bites mightn’t kill as many people as they once did, but that’s hardly a reason to risk it. Snakes also pose a serious threat to pets, who don’t always have the foresight to avoid them like humans do.

Mosquitoes 

Mosquitoes may be some of the smallest pests around, but they spread more diseases than any other animal on the planet.

In Australia, common (and serious) mosquito-borne diseases include Dengue fever, Ross River fever, Barmah Forest virus and Murray River encephalitis. All of these diseases can be deadly, and not just in the northern states. Even cities in cooler climates such as Melbourne are increasingly experiencing cases of these mosquito-borne diseases.

Pools of stagnant water such as the water in your downpipes or clogged gutters can create an ideal breeding ground for mosquitoes. Once the larvae have matured, they can begin spreading disease themselves, seriously threatening your home’s health. 

 

Prevention vs cure 

Removing pests in order to protect your home’s health can be an expensive exercise. If you already have pests resident in your roof and gutters, pest removal is certainly necessary. But if not, then prevention is always better than the cure.

If you want to prevent pest-related health hazards around your home, you need to keep pests out in the first place.

And the most effective way to do this is to use over-the-gutter gutter mesh.

Why gutter mesh? 

High-quality, over-the-gutter gutter mesh forms a physical barrier over your gutters and the gaps between your gutters and roof.

Because it cuts off access to both your gutters and roof, using over-the-gutter gutter mesh is an effective way to keep pests out, defending your home against animal invasion and the health hazards these pests bring.

Further protection is provided because the gutter mesh is installed in line with the roof angle to create a continuous slope. This helps to encourage leaf and debris blow-off while still letting rainwater in, preventing the kind of clogging and water pooling that often attracts mosquitoes.

Which gutter mesh?  

Pests vary in weight, size and dexterity. If you’re serious about keeping them out, it’s important that you select a metal gutter mesh that’s strong enough to withstand attack from the pests in your area.

To help you select an appropriate gutter mesh product for keeping pests out of your roof and gutters, Blue Mountain Co has developed Mesh Matcher. Mesh Matcher asks the right questions in order to identify which gutter mesh products will provide optimal protection against the pests in your area – and defend your home against other relevant threats.

The Growing Bushfire Threat 

Australia’s bushfire seasons are becoming more intense and unpredictable. The devastating 2019–2020 Black Summer fires burned over 24 million hectares, destroyed more than 3,000 homes, and impacted communities across the country (Statista, 2023). And the risks are only increasing: 

  • Fire seasons are starting earlier and lasting longer. 
  • Extreme fire weather is becoming more frequent. 
  • The annual area burned is growing. 

Prolonged droughts, rising temperatures, and drier landscapes are creating the perfect storm for fires to ignite and spread rapidly (Bowman et al., 2017). In some regions, fire seasons are now over a month longer than they were 35 years ago (NASA, 2023). 

Your Gutters: A Hidden Fire Risk 

When it comes to bushfire preparedness, many homeowners focus on clearing vegetation around their property. But one critical weak spot is often overlooked—gutters.This phenomenon, known as an ember attack, is responsible for up to 90% of homes lost in bushfires (Leonard et al., 2016). Dry leaves and debris in gutters provide the perfect fuel, allowing fire to spread to the roof and into the home within minutes. 

Gutter Protection: A Simple Yet Powerful Defence 

 
Investing in effective gutter protection is a key step in reducing your home’s bushfire risk. At Blue Mountain Gutter Mesh, we offer premium ember guard-compliant gutter mesh, designed to defend against ember attack. Our 2mm steel and aluminium gutter mesh options meet Australian Standard AS3959-2018 for ember guard compliance while preventing flammable debris buildup in your gutters—a critical factor since up to 90% of bushfire-related property losses stem from ember ignition. Crafted from non-combustible, corrosion-resistant materials, our mesh keeps embers and leaves out, safeguarding your home. 
 
2mm Steel Gutter Mesh: Ember guard compliant for all BALs (12.5, 19, 29, 40 and Flame Zone) 

2mm Aluminium Mesh: Features a woven edge for extra durability and is ember guard compliant for BALs 12.5, 19 and 29. 

5 Signs Your Gutters Need Protection Now 

  1. Leaves and debris constantly build up. 
  2. Water spills over during heavy rain. 
  3. Your gutters are sagging or pulling away. 
  4. Stains or water damage appear on exterior walls. 
  5. You live in a bushfire-prone area. 

Bushfire Readiness Checklist: 

✅ Install ember guards to your gutters 
✅ Regularly clear gutters and roof valleys. 
✅ Remove flammable materials from around your home.
