Everyone recognizes that distinctive buzz and the sting of a mosquito. They are attracted to the carbon dioxide we exhale and components of our perspiration. When considering mosquito season, you need to consider the weather zone we live in and therefore, Delta is particularly vulnerable to mosquito season in summer and into the fall. So when do mosquitoes go away? Only when the weather begins to cool down will the mosquitoes begin to start looking for a place to hide and hibernate. But some mosquitoes can appear again if there are unexpected warm spells during winter. If mosquito’s are still bugging you use insect repellent, wear protective clothing, protect your house with barriers, don’t leave stagnant water around and avoid gathering where mosquitoes are.
