As the temperatures drop and Indiana settles in for winter, you might breathe a sigh of relief, thinking you’ve seen the last of those buzzing, biting pests for a few months. While it’s true that you won’t be swatting away mosquitoes during a snowstorm, they don’t simply vanish. Many have clever survival strategies to endure the cold and return in full force come spring.
This article explores how mosquitoes survive Indiana’s harsh winters, what that means for the upcoming season, and how you can prepare your property for their return.
Where Do Mosquitoes Go in the Winter?
When temperatures consistently fall below 50°F, mosquitoes become inactive. While adult mosquitoes from many species die off, they ensure their lineage continues through a few key survival tactics. According to experts at Purdue University, Indiana mosquitoes primarily survive over winter in one of two ways: as dormant eggs or as hibernating adults.
Overwintering as Eggs
Many mosquito species, including the common and aggressive floodwater mosquitoes like Aedes vexans, lay their eggs on moist soil or in empty containers where water will eventually collect. These “delayed-hatching” eggs enter a state of dormancy and are incredibly resilient. They can survive freezing temperatures and long dry periods, waiting for the spring thaw and rain to hatch. This is why you often see a sudden explosion of mosquitoes after the first warm spring rains.
Hibernating as Adults
Other species, particularly those from the Culex genus (known as “house mosquitoes” and vectors for West Nile Virus), survive the winter as mated adult females. These females find shelter in protected, quiet places to hibernate. Common hiding spots include:
- Caves
- Culverts
- Animal burrows
- Basements, garages, and sheds
- Hollow logs or tree holes
These females remain dormant until warmer weather returns, at which point they emerge ready to find a blood meal and lay their first batch of eggs.
Preparing for Mosquito Season
Because mosquito eggs can survive the winter right in your backyard, what you do now can impact how many mosquitoes you’ll face in the spring. Once the weather warms up, it’s a good idea to inspect your property for potential breeding grounds.
Key actions you can take include:
- Removing standing water: Tip over any containers that can hold water, like flower pots, buckets, and wheelbarrows.
- Cleaning gutters: Clogged gutters are a prime spot for mosquitoes to lay eggs.
- Managing tires and tarps: Discarded tires and folds in pool covers or tarps can collect enough water for larvae to develop.
By taking these steps, you can help reduce the local mosquito population before it has a chance to thrive.
Get Ahead of the Mosquito Bites
While mosquitoes may be out of sight during the winter, they’re certainly not gone for good. Their ability to survive the cold means they’ll be back as soon as the weather warms up.
