One consolation I have long taken from intense cold snaps Iike the one we are experiencing now is that it would kill off more mosquitos and lead to a less buggy season next summer. If you have also had this understanding, I am sorry to inform you that we’ve been wrong.
It is true that mosquitoes become less active when the temperature drops below 50 degrees. And many do die with the onset of freezing temperatures. But they long ago evolved as a species to handle cold winters. Depending on the species, they either enter hibernation or lay eggs. And in both cases the creatures are able to withstand much colder weather than we’re dealing with right now.
And really, that makes a lot of sense, seeing as places like Alaska or northern Canada have huge swarms of mosquitos, despite also having bitterly cold winters.
The good news? There is one climate phenomenon that actually can reduce the mosquito levels. As insect expert Dr. Daniel Markowski told WUSA a few years ago: “consistent cold isn’t as bad for mosquitos as cycles of warm and cold days that keep waking them up throughout the winter. Waking up burns energy, and if it happens often enough, it can be deadly for the insects.”
So if we get a nice midwinter thaw, followed by another freeze-up, not only will that give us a respite from the cold, it may actually make our summer gardens a bit more pleasant!
