Put it in corners. They will work wonders 😱 

That's what I've done for years!

thecatatemyhomework "There is something called screens." haha, not in Europe! And there are idiots who can't close the door when they come in.

To thecatatemyhomework- Well, you don't have to use it! And, "There's no reason for mosquitos or flies to enter your home. There is something called screens!" Not just in Europe, but not in rentals either! And obviously you have never had to live in a run-down, nasty, neglected place that has not seen caulking in over 50 Years! And, probably came infested with the bugs to begin with! Only people of low incomes would understand that! You are fortunate to be from an "upper income". It did not help you with your manners though!

We done have screens on our doors and windows in the uk.
