Loads of greenflies keep flying through my window when I put light on. What is the best way to kill them?

Question

I can not put up a net curtain it is rented privatly so can not put anything up. I have tried citonelia in a tea candle and fly spray but doesn't work.

Answer 1

Make a removable window screen that you can wedge into the window frame.  Even 1/2X1/2 wood, would hold the screen.  You could make it fit the opening or if you have a sill it could rest on the sill.  The yellow bulb will work but is not bright enough to read by.

Answer 2

Shut the window

Answer 3

Get hold of some ladybirds.  They eat greenfly.

Next question: how to get rid of the ladybirds?  

Answer 4

Personally, I would shut the window.

Answer 5

Electronic bug zapper.

Answer 6

Probably easiest to just ignore them. It doesn't really bother me all that much

Answer 7

I  think  they  have  a  short  life  span.  You need  a  window  screen.  Also  can  use  a  sticky fly strip.

Answer 8

Don't put a white light out.  Put a yellow tinted one.  That will help.
