Recent high heat, humidity increases mosquito activity


SPRINGFIELD, Mass (WWLP) — EEE has been officially confirmed in Franklin County this year and amid a rising risk, the weather conditions we’re experiencing in western Massachusetts are making mosquitoes more active.

The best conditions for peak mosquito activity are temperatures in the 80s with high humidity, according to Orkin and that’s what we’ll see over the coming days.

However, during periods of heavy rainfall, that temporarily reduces mosquito activity as it prevents flight since heavy rain can cause injury. Once the rain is over, activity increases as frequent rainfall maintain higher water levels, which mosquitoes like.

We’ve already had a wetter-than-normal pattern so far this month and the forecast over the next week shows even more rain to come.

Wind also plays a factor in mosquito activity. Little to no wind is favorable to mosquitoes since they are not strong flyers.

Regardless of the weather, the best way to prevent mosquito bites is by using a repellent containing DEET.
