I have a small garden and beside it there is a small toilet. There are always many drain flies stuck on the door and inside the toilet walls. Somebody gave me a suggestion to make soap water and spray it on them, but it did not work.
How can I make them fly away for ever? What solution or chemicals can work on them?
You could try pepper extract. Crush very hot peppers in water, let soak, then filter. Wipe this onto a test area and see if this repels the flies.
Or just use pesticide spray on the walls. Use one of the fairly non-persistent products that contain chlorpyrifos or chlorpyrifos-methyl or permethrin. If the flies are getting in around a loosely fitting door, you might get some control just spraying the edge of the door and the jamb.
Are you USING this toilet? The best thing would be add lots of lime and fill it in...I am assuming this is an outhouse and not attached to the city sewer. Too cute.
He (she) is called drain fly or bathroom fly or moth fly. Psychodidae, Clogmia albipunctata, used to be in Pericoma.
Get rid of the problem get rid of these cute flies. If you were to go in like Ghost Busters and spray stuff to kill them all, these same flies would find this bathroom of yours and fill it up again.
Of course you knew all of this...
