There's nothing like being able to keep your windows open once summer comes around and being able to get a fresh breeze inside your house.
However, the downside to having your windows open is that you inadvertently invite pesky flies into your home, who buzz around like they own the place.
This can spell even further trouble if you have pets in the house, who may hurt themselves if they chase the insects around. It can be difficult to know what to do for the best though.
