DIY Rain Barrel Screen: How to Keep Out Mosquitoes and Debris

Looking to harvest rainwater and reduce your water bills? A DIY rain barrel screen is an eco-friendly and cost-effective addition to your home. Not only does it help you collect rainwater, but it also prevents mosquito infestation and debris buildup. Here's a comprehensive guide on creating and maintaining your DIY rain barrel screen.

Before we dive into the details, ensure you have all the necessary supplies. You'll need a 55-gallon rain barrel, a hacksaw or reciprocating saw, a screen material like window mesh or galvanized steel window screening, staple gun, staple remover, and scissors.

Creating Your DIY Rain Barrel Screen

Now that you have all the supplies, it's time to get started. The first step is to cut the top of your rain barrel to create an opening for installing the screen.

Measure and mark the top of your rain barrel where you'd like the screen to sit. For most barrels, this is around 1-2 inches from the top. Use your saw to carefully cut along the marked line. Be cautious and wear safety glasses during this process.

Choosing and Installing the Screen

For your screen, opt for a material with tight weave to keep out mosquitoes and debris. Window mesh and galvanized steel window screening are both excellent choices. You can usually find these at a local hardware or home improvement store.

Measure and cut your screen to fit the opening you've created. Leave a slight overhang around the edges to secure it into place. Once you've cut your screen, use your staple gun to attach it to the inner lip of the barrel opening. Start by stapling in one corner, then stretch the screen taut and staple it in place around the entire opening.

Finishing Touches and Cleanup

After you've stapled the screen into place, use the staple remover to remove any staples that might have gone through to the outer lip of the barrel. These can be sharp and hazardous. Trim any excess screening with scissors.

Clean up any debris or sawdust from the top of your rain barrel. Now, your DIY rain barrel screen is ready for water collection. Simply position it under your gutter downspout, and you're all set.

Maintaining Your DIY Rain Barrel Screen

Proper maintenance will ensure your rainwater collection system continues to work efficiently and safely. Regularly inspect your screen for tears or noticeable wear.

To clean your screen, simply remove it using the staple remover and rinse it off with a garden hose. If there's heavy buildup, use a soft-bristled brush and mild soap to scrub it clean. Always make sure the screen is completely dry before reinstalling it.

Preventing Mosquito Breeding

Controlling mosquitoes is crucial when collecting rainwater. Besides using a tight-weave screen, add a few drops of non-toxic biodegradable soap to your barrel occasionally. This disrupts the surface tension of the water, preventing mosquitoes from laying eggs.

Additionally, consider adding a clean, flat marble or a few fish to your barrel as a natural mosquito deterrent. These won't harm the environment, and they can help keep mosquitoes at bay.

Investing in a DIY rain barrel screen is a smart way to save on water bills while being environmentally conscious. With proper maintenance, your homemade screen will serve you well for years to come. Happy rainwater harvesting!
