Welcome to DC! Here’s Why Your Outdoor Drains Could Be a Mosquito Magnet (And What to Do About It)

If you’re a new homeowner in the DC area — congratulations! You’re settling into one of the most vibrant cities in the country, with beautiful outdoor spaces, historic charm, and… well, let’s be honest — some pretty persistent mosquitoes.

One of the biggest hidden mosquito breeding grounds in your yard? Your outdoor drains.

Why Drains Matter More Than You Think

Mosquitoes love standing water — and outdoor drains, catch basins, and even French drains can easily collect stagnant water without you even noticing. These quiet, damp spots create the perfect environment for mosquito larvae to hatch and thrive.

Unlike puddles or birdbaths, drains are out of sight and hard to reach, making them a serious, often-overlooked source of infestations.

The Problem with a DIY Approach

As a new homeowner, it’s tempting to take a DIY approach to pest control. Maybe you’ve tried sprays, citronella candles, or even mosquito dunks in birdbaths — and while those can help, they won’t get to the root of the problem if mosquitoes are hatching underground in your drains or along your property’s perimeter.

That’s where large-basin treatments come in.

What is a Large Basin Treatment — and Why Does It Work?

At DC Mosquito Defense, we specialize in identifying and treating hidden mosquito breeding areas, including underground drain systems and large catch basins.

Our large-basin treatment involves:

• Inspecting your property for hidden water collection zones

• Applying larvicide and residual treatments that are safe for your family and pets but deadly for mosquitoes

• Creating a protective barrier that keeps mosquitoes from returning

These treatments are especially important in urban areas like DC, where aging infrastructure, high humidity, and tree-lined neighborhoods create the perfect storm for mosquito activity.

The Local Advantage

We’re a locally owned, family-operated company, and we know DC’s mosquito patterns better than anyone. Our treatments are tailored for the unique challenges of this area — especially for homeowners with older homes, mature landscaping, or complex drainage systems.
