As temperatures drop and the last of the summer mosquitoes disappear, many Maryland homeowners breathe a sigh of relief. But here’s a surprising truth: Maryland winters don’t always kill mosquito eggs.
In fact, those tiny, almost invisible eggs may be waiting silently in your yard, ready to hatch once the weather warms back up.
Let’s take a closer look at how mosquitoes survive the winter—and what you can do now to stop them before they start buzzing again.
🦟 Mosquito Eggs Are Tougher Than You Think
While adult mosquitoes can’t survive Maryland’s freezing winter temperatures, their eggs are built to endure the cold.
Species like the Aedes mosquito (which includes the common Aedes albopictus, or Asian Tiger Mosquito) lay their eggs in areas where water tends to collect—think flower pots, gutters, and buckets.
Once the temperature drops, these eggs enter a dormant state called diapause. In this state, the eggs essentially “pause” development until conditions become favorable again in spring.
🌡️ Why Maryland’s Winters Aren’t Always Cold Enough
While Maryland can experience snow and freezing temperatures, recent winters have often been milder than in the past. These warmer winters mean that mosquito eggs are less likely to be killed by the cold.
Even brief warm spells can encourage early hatching, leading to mosquitoes showing up earlier each spring.

🏡 Where Mosquito Eggs Hide Around Your Home
You might be surprised where mosquito eggs can survive over the winter. Here are a few common hiding spots:
Clogged gutters that hold stagnant water
Toys or flower pots left outside
Birdbaths or tarps collecting rainwater
Old tires that trap moisture
Low areas in your yard that tend to stay damp
Even a bottle cap of water can hold enough space for mosquito eggs.
🌱 How to Prevent Mosquito Eggs from Surviving the Winter
You can take action now to reduce next year’s mosquito population:
Empty and store containers that hold water.
Clean gutters regularly to keep water flowing.
Cover or turn over items that can collect rain or snowmelt.
Schedule a professional mosquito inspection to locate potential breeding sites before spring.
