1. Spraying White Vinegar Around Windows
White vinegar is strong enough to repel insects away from your windows and help you bug-proof your home.
To prevent indoor fly of mosquito infestations, dilute 150 ml of white vinegar in 150 ml of water and shake the mixture in a spray bottle. If you don’t have one, use a sufficient amount of the two substances and let the mixture soak into a clean rag. Then, sprinkle the inside and outside of your window’s frame.
If your windows are old consider replacing them, because it’s easy for bugs and insects to slip through them.
