At What Temperature Do Mosquitoes Die or Go Away?

In areas of the country that experience an actual winter season with temperatures below 50° F, mosquitoes will slow down when the temperature drops as they are cold-blooded and don’t possess the ability to regulate their internal temperatures. In regions that experience below freezing temps, mosquitoes tend to eventually die, hibernate or migrate to warmer climes.

Eliminating items that collect water around your property will help prevent mosquitoes as well as trimming dense brush back and reducing shady areas where mosquitoes hide in the day time. Professional pest control companies, such as Uprooted Pest Control, can stop this vicious cycle with mosquito reduction programs. Contact Uprooted Pest Control in Dunedin, FL to address your mosquito concerns and keep your family safe in and around your home.

At what temperature do mosquitoes die?

Most mosquitoes stop flying and feeding at about 50°F (10°C) and become sluggish well before that. Sustained temperatures below freezing kill the active adults. But mosquitoes rarely die off as a population. Depending on the species, the females hibernate in sheltered spots like sheds, culverts and tree holes, or the eggs simply wait in dry soil and containers until warm rain returns.

What temperature do mosquitoes go away?

Activity drops sharply once evenings fall below 50°F, and you will notice far fewer bites below 60°F. They are most active between 80°F and 95°F with high humidity, which describes most of the year on the Gulf coast of Florida.

Why Florida mosquitoes never really leave

Dunedin and Clearwater average winter lows in the low 50s and only see a handful of nights near freezing. That means mosquito season here runs roughly March through November, and a mild winter can keep them biting straight through. Standing water from afternoon storms, irrigation overspray and bromeliads gives them a place to breed every week of the year.

How to keep them down year round

• Tip and toss anything that holds water every week: plant saucers, gutters, toys, tarps, bird baths.
• Trim dense shrubs and ground cover where adults rest during the heat of the day.
• Treat the resting areas and breeding spots on a schedule, not just after you get bitten.

A monthly mosquito reduction program from Uprooted Pest Control targets the shaded resting spots and larval sites around your yard. Contact us in Dunedin, FL for a free quote.
