Mosquito Forecast

For Rowan County — Sunday, October 5, 2025

Overview

As October begins, mosquito activity across Rowan County is finally on the decline. Cooler nights and lower humidity are limiting mosquito breeding, but a few warm afternoons this week will still be favorable for brief bursts of activity — especially near standing water and shaded areas.

Current Conditions

• Mosquito Activity: Moderate (mainly during late afternoon and early evening hours)

• Temperature Influence: Highs near 80°F early this week will keep mosquitoes active before the midweek cooldown.

• Humidity: Dropping humidity levels behind each cold front make conditions less favorable for new hatches.

Peak Hours

• Most Active: 5:30 PM – 8:00 PM

• Least Active: Overnight through early morning

Calm winds and lingering evening warmth create short windows of higher activity, particularly before frontal passages.

Breeding Hotspots to Watch

• Clogged gutters and birdbaths

• Plant saucers and flower pots

• Tarps and covers that collect rainwater

• Areas with slow-draining puddles after midweek showers

Even small amounts of standing water can produce dozens of new mosquitoes in just a few days when temperatures stay above 65°F.

Outlook for the Week

• Sunday–Tuesday: Moderate risk — warm afternoons, light winds, and patchy standing water possible.

• Wednesday–Thursday: Declining activity with cooler, drier air behind the cold front.

• Friday–Weekend: Low activity — overnight lows in the 50s and reduced humidity limit breeding.

Prevention Tips

• Empty or dump standing water every 2–3 days.

• Keep porch lights off when not needed (they attract insects).

• Use EPA-approved repellents for outdoor events.

• Check window and door screens for tears or gaps.

Quick Take

Mosquito season is fading fast, but a few warm afternoons will still keep them buzzing early in the week. Once the midweek front moves through, Rowan County will finally see a noticeable drop in mosquito activity — a sure sign that fall has arrived.
