Mosquitoes can follow you into your home or enter through unscreened doors and windows that have been left open or are opened frequently. Screening your doors and windows is a great solution to prevent mosquitoes from entering homes. Regularly check your screens to make sure they fit tightly into the window or door frame and that there are no holes. Also, make sure you do not have standing water inside your homes. Vases, plant trays, and unused bathrooms are potential breeding sources for the invasive Aedes mosquitoes. See Mosquito Sources for more details about mosquito sources and how to properly manage them.
