Why Mosquitoes Swarm After Springtime Rains

Mosquitoes love refreshing springtime rain in Austin as much as we do. Here’s why you’ll see more mosquitoes after these rains.
Temperate weather in Austin during the spring is a big bonus for area residents. And when a cloudburst comes through, washing away pollen and dust, the whole of the outdoors feels renewed. What you don’t see as a result of springtime showers, big or small, is how well they bode for the local mosquito population. If you’re a major mosquito magnet or simply hate swatting swarms of mosquitoes when trying to work or relax outside your home, here’s what you need to know is happening behind the scenes in the insect world.
Spring Showers Bring Mosquito Nurseries
Even the tiniest rain puddle can become an ideal mosquito egg repository. Once female mosquitoes obtain enough mammalian blood, they will have fertilized their eggs, whereby they are able to deposit up to 300 of them in any given still water source at a time. During her lifetime, a female mosquito will lay up to 500 fertilized eggs.
FUN FACT: A batch of mosquito eggs is called a raft.
Spring Showers, Warm Temps Hasten Mosquito Larval Growth
The same weather conditions that turn our yards into veritable mosquito maternity wards, is also responsible for accelerating the growth of larval mosquitoes. Warm, humid conditions are just the right environment for them to get a move on and develop into pupae already. This is a process that already happens quickly, requiring only two to three days to being with.
FUN FACT: Mosquito larvae are a food source for dragonfly larvae, toads, spiders, and some flies – just to name a few.
Spring Showers Allow Protective Mosquito Canopies to Grow
As local vegetation is nourished by springtime rains, it provides shady spaces for mosquitoes to hide away from the daytime sun. Not only do mosquitoes thrive in these shady areas around our yards, but other outdoor pests seek shelter there too. Ticks, for instance, often live beneath thick vegetation, wood piles, decks, and other protected spaces.
FUN FACT: While mosquitoes seek shady vegetation, you can install plants that will not attract them. In fact, some plants repel mosquitoes, like lavender, mint, sage, and citronella.
In summary, spring showers and warmth bring mosquito nurseries, hasten larval development, and grow mosquito shade canopies.
