For various reasons, that are impossible to change, I find myself with too many flies in the house.
I need an automated system ( or passive system ) that gets rid of them, so no salt gun, fly squashers.
Additional exclusion, no sprays or sticky tapes, and nothing that stinks ( like the Bunnings fly trap ).
Well simplest would be to solve the problem of why you have them… An open window needs mesh, etc etc
