Keeping Pests Out of your Rain Harvesting System & Gutters

Keeping Pests Out of your Rain Harvesting System & Gutters

by | Jul 26, 2022 | Keeping Out Pests

Successful Rain Harvesting gives you clean rainwater – and lots of it – for use around your home or property.  

However, the presence of pests (large and small) in your gutters can compromise this water supply, reducing the volume of rainwater you collect or adversely affecting its quality.  

Because of this, measures that will keep pests out of your gutters are an important consideration in the design of any Rain Harvesting system. 

 

The problem with pests 

Pests can create a range of problems for your rainwater system.  

Pests that build nests or that die while on your roof can clog your gutters and reduce the volume of water that ends up in your tanks. This reduced quantity can prevent you from using your rainwater as much as you would like, and increases the negative effects of drought and low rainfall on you and your system.

Pests of all sizes can also contaminate your rainwater supply with urine, faeces, their own carcasses and other unpleasant things. In turn, this affects the opacity, colour and odour of your rainwater, and may even render it completely unfit for its intended uses, leading to water wastage and shortages.

Clogged or underperforming gutters can also become a breeding ground for the smallest pests of all, mosquitoes. These unwanted residents can seriously affect the health of your entire Rain Harvesting system (and your home, too).

Keeping pests out 

The most effective way to prevent pest-related problems in your Rain Harvesting system is to keep pests out of your gutters, as this tends to keep them out of the rest of your system as well.

One recognised way for keeping pests out of your gutters and rainwater system is to install over-the-gutter metal gutter mesh. Over-the-gutter gutter mesh forms a physical barrier over your gutters, letting rainwater in but preventing pests (and leaves and debris) from entering. All Blue Mountain Co Gutter Mesh is strong enough to prevent pests from getting into your gutters.

By keeping pests out of your gutters, gutter mesh helps to preserve and improve the quality and quantity of your rainwater so you can enjoy a clear, colourless, odourless and plentiful supply.

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. 
✅ Practice your evacuation plan with your family. 

The risk of bushfires is real—and growing. Don’t wait until the flames are at your doorstep. Protect your home now, starting from the top down.
