Is That a Mosquito in the Fall?

Is That a Mosquito in the Fall?

When the air becomes crisp and the leaves begin to fall, we breathe a sigh of relief that mosquitoes are fully, finally gone. But are they?

After all, autumn typically signals a slowing down of these buzzing, biting, blood-suckers. And after a long spring and summer season in the biting and breeding business, aren’t they eager to go away? Sure they are – but if we see a couple of warm autumn days, they’ll break their respite and get right back to work.

Warm Spells Often Equate to a Mosquito Encore

And they’re not playing their greatest hits! Mosquitoes are not just marking their calendars and packing it in the first day of fall. While the length of daylight affects their activity, in the St. Louis area, unseasonable warmth will stir them once more. Next thing you know, that warm fall morning you’re spending in the yard will be shared with mosquitoes (and other pests too).

Their numbers are not nearly as high as they were in peak season, but it doesn’t take a whole swarm to ruin your fun this fall. One or two hungry mosquitoes is enough to drive you crazy dodging and swatting. And it only takes one bite from an infected mosquito to make you ill.

Don’t Fall Victim to Autumn Mosquitoes

Due to the smaller number of potential mosquito invaders this time of year, you might choose not to treat your yard professionally. There are other avenues that you can take to manage mosquitoes in autumn, like personal mosquito repellents, citronella candles, or even a fan to blow them away from you.
