WHERE DO THE MOSQUITOS GO?

Winter is not something most people look forward to. The days are shorter, the weather is colder, and all the greenery turns brown. We long for those long, warm days outside with friends and family. While winter may not be a favorite season to everyone there is one thing that we may all agree on, we are always glad to see the mosquitos leave. However, does it every cross your mind, where do all the mosquitos go?

It is common misconception that they simply die off with the arrival frostier days. Surprisingly, these little pests do not just simply die off, and exactly how they survive differs between species. Some species of mosquitos deposit their eggs to wait out the winter and allow the next generation of offspring to hatch in Spring.

As temperatures begin to fall below 50 degrees, females will make a final egg deposit in water-holding items, some holding as little as half an inch of water. Eventually the adults do die off in the cold, but the eggs go into a state of diapause. This process will delay their development allowing them to survive the coldest months.



Whenever temperatures begin to rise, and rainfall becomes more frequent the eggs will be re-submerged and hatch to begin a new age of mosquitos. While I know that this is not something to look forward to here are some preventative measures to help avoid these unwanted guests:

• Check your property for items that can hold water, that would allow for mosquitos to deposit eggs during winter months. Items such as flowerpots, birdbaths, tire swings, grill covers, and other objects where water collects easily.
• Clean out gutter, repair any leaky pipes or faucets on the outside, drill holes in the bottom of tire swings and wheel barrels to ensure water is draining out, and make sure trash cans are sealed tight and liquids aren’t being thrown in without a bag.
• Make sure to be applying insect repellent when doing outdoor activities, especially if you are in an area that does not typically fall below 50 degrees. Repellents that are most effective have 20% DEET, picaridin, or oil of lemon-eucalyptus.
