Early Season Mosquito Activity: What You Need to Know

This spring, many residents are noticing mosquitoes much earlier—and in greater numbers—than usual. We want to share what’s causing this increase, what it means, and what we are doing to respond.

Why Are Mosquitoes Active So Early?

The mosquitoes you are seeing right now are overwintered adults—they survived from late Summer and Fall of 2025 and have emerged from winter dormancy.

While it is normal to see a few mosquitoes during warm days in early spring, this year’s milder winter and warmer early spring temperatures allowed more mosquitoes to survive than usual. As a result, we are seeing a larger and more active early-season population.

These overwintered mosquitoes are nearing the end of their life cycle. Their primary goal is to feed, lay eggs, and then die. However, their activity can still be noticeable and frustrating in the meantime.

What We Are Doing

Our team is actively responding to this early surge in mosquito activity. Current efforts include:

• Monitoring mosquito populations to track activity levels and identify hotspots
• Preparing and calibrating equipment for the upcoming treatment season
• Repairing and maintaining fogging units to ensure they are fully operational
• Planning treatment routes so we can respond quickly once conditions allow

We are accelerating our normal seasonal preparation timeline due to the earlier-than-expected mosquito activity.

Why Fogging Hasn’t Started Yet

Mosquito control treatments, including fogging, depend on both weather conditions and regulatory requirements.

• March temperatures are often too cold for effective fogging
• Our operational permits allow fogging to begin in April

While we are preparing as quickly as possible, treatments must begin when they are both effective and permitted.

Earlier Than Expected—But We’re Adapting

This level of mosquito activity in early spring was not anticipated. However, our staff is working diligently to adjust operations, prepare equipment ahead of schedule, and be ready to respond as soon as conditions allow.

How You Can Help

Community participation is key in reducing mosquito populations. You can help by:

• Eliminating standing water around your property
• Reporting areas with high mosquito activity
• Using personal protection such as repellent when outdoors

Thank You for Your Patience

We understand that early mosquito activity can be frustrating. Please know that our team is actively preparing and will begin treatments as soon as possible.
