I had a dream and a man with hair up to his neck said to me, “If you kill a roach, you shouldn’t kill him during the nights of the last ten days of ramadan because when the angel comes down he will see you killing something and not making dua’
Answer
It is permissible to kill roaches at any time including the last ten nights
of Ramadan.
And Allah Ta’ala knows best
