What Is the Worst Time of Year for Mosquitoes?

When is the worst time of year for mosquitoes? Probably not what you think.

Most people seem to think that summer is the peak time of year for mosquitoes. The hot, muggy summer when everyone is outside seems to fit into the narrative of the worst time of year for mosquitoes. People at the beach, at the pool, at a cookout, etc. with these bothersome blood suckers swirling around comes to mind. People are swatting them away, itching from past bites and hating mosquitoes more each day. Sounds miserable, right? But it isn’t the worst time of year for mosquitoes. Not by a long shot.

The absolute worst time of year for mosquitoes is the Fall. Yep – between late September and into November (depending on when you get your first freeze) but it is right around the first day of Fall that begins the worst time of year for mosquitoes.

How can that be? They don’t seem to be nearly as bothersome… but perhaps that is because you aren’t outside as much. Once school starts each year, outdoor activities seem to slow down. People aren’t around these buzzing pests as much this time of year so how is it the worst?

Because Fall is the time of year that mosquitoes carry the most diseases.

You rarely hear about West Nile Virus in May. Eastern Equine Encephalitis doesn’t get going until late in the season. If you look at the Centers for Disease Control Data on mosquito-borne diseases, the incidences rise considerably as Autumn comes along.

Depending on where you live, the mosquito population varies. The northern climates basically eliminate these pests completely over the freeze of the winter. Each Spring, the new hatchlings are a fresh new batch that haven’t been exposed to diseases however, consequently have little to spread. The further south you live, some mosquitoes can continue to procreate by the cooler months, but the populations are considerably reduced and the harboring of diseases reduced.

Once a new crop of skeeters begins to appear in the Spring, the opportunity for diseases starts the slow incline to peak in the Fall. Hotter weather creates more stagnant water which are the perfect breeding spots. As time passes, these blood suckers migrate to more high grounds where food supplies are abundant. Anywhere livestock and animals hang around or where people gather frequently are mature for abundant supplies of blood to suck. The more victims any given mosquito bites, the greater the chance to spread disease. In other words, if a mosquito bites just you, there is likely no disease. If a mosquito that has fed on 100 other people bites you, the likelihood of giving you an illness grows exponentially.

This time of year, it is imperative to protect yourself and your family from mosquito bites to avoid the diseases they can carry. Make sure this Fall is not YOUR worst time of year!
