Where Do Mosquitoes Disappear to in the Winter?

Many of us get excited for fall and winter for one reason- because the mosquitoes are gone. But, are they really gone?

Unfortunately, it’s a widely-believed misconception that mosquitoes simply die off or go elsewhere when it gets cold outside. Believe it or not, this isn’t what happens. Exactly how a mosquito survives the winter can differ by species.

As an example, as temperatures begin to drop, the mosquitoes responsible for transmitting Zika virus, Aedes aegypti, deposits their final batch of eggs in water-holding items. The adults will eventually die, while the newly deposited eggs enter a state that suspends their development during the coldest months. When temperatures begin to rise and rainfall picks back up again in spring, the eggs are re-submerged and hatch to start the next generation of Aedes mosquitoes. These mosquitoes will undoubtedly seek out humans as a food source. Even more alarming, though, is the fact that these offspring could be infected with Zika.

Mosquito Prevention

The best way to exercise caution this fall and winter is to carry over all of your mosquito-safe habits from the summer, as follows:

  • Inspect your property now for water-holding items that could contain mosquito eggs deposited during the warmer months. These items may include flowerpots, birdbaths, tire swings, grill covers and other objects where water collects.
  • Unclog gutters, repair any leaky pipes or faucets on the outside of your home, drill holes in the bottom of tire swings and wheel barrels to allow water to drain, and ensure trash cans are tightly sealed and lids aren’t flipped upside down.
