As winter quickly approaches in northern regions and in many areas in the south that expect cooler temperatures, there are a few standard updates that we all make to our homes to prepare for snow and the other winter risks. As you’re pulling out the shovels and sealing cracks to prevent drafts, there are a few things you can do now to avoid a heavy influx of mosquitoes in the spring.
Once the temperatures drop consistently below 50°F, mosquitoes will either hibernate or lay eggs in standing water and then die shortly after. The biggest thing that you can do is eliminate any standing water. Even if the top freezes during the winter, eggs can still survive in the water throughout the winter, and then hatch in the spring to begin the lifecycle all over again. Look for pools of water in old tires, on top of tarps, in gutters, within playsets, in birdbaths, and anywhere else there might be stagnant water. Check your water sources for any leaks, even in garages, barns and cellars, as mosquitoes can find their way in and lay their eggs for the winter.
Even though it seems improbable, certain species of mosquitoes opt to hibernate during the winter. The best thing you can do in this case is to eliminate any sources for them to successfully hibernate in or near your home. Once the temperatures start to drop, these mosquitoes will look for sugar-rich food sources, switching from biting humans to scoping out rotting fruit or nectar. Make sure that any compost or trash areas are fully covered as an initial precautionary measure, as well as ensure that the areas around fruit-bearing trees have been completely cleared. Then do a check of your garage, barn, cellar, attic, or any unattended, indoor space that mosquitoes could nest in during the winter. Sweep and vacuum corners, clear out any rubble, and make sure to check for any dead mosquitoes that you may come across. These could be indicative of groups of mosquitoes nearby.
Sometimes there’s only so much you can do on your own. If you live near a wooded area or close to ponds/other pools of water, mosquitoes can opt for muddy bottoms of pools to protect their larvae from freezing. This allows them to stay dormant over the winter and develop in the spring. Proactively spraying your yard will mitigate the risk of these areas that you wouldn’t be able to tend to yourself.
