VAPE mats, great things. You need to buy the electrical gadget that the Vape mats go on and the mats. Most of the local supermarkets have them--Super Buy, SP Supermarket, Richie's etc.
Plug in, put in a little blue mat. If the house is full of mosquitos, close all windows and doors for a while with the mat on, then I usually open my windows and doors that are protected with screens.
