The cockroaches

Its been a few months that our pest control for  house has expired and the cockroaches have started showing up in the kitchen. Due to covid, I obviously don't want to get it done anytime soon either. As an alternative to control that, I started to clean the house at night. As soon as the dinner gets over, the kids start their sleep routine and I start cleaning. The kids obviously noticed that and kept coming back to see me vaccuming the house. The 2yo asked for a week in row "mumma al you ceanin?" 😁 ,& 6yo seemed fine with it until yesterday.
Today afternoon she asked me as to why I started cleaning at night. I explained everything to her. She almost screamed " Stop doing that mom. You don't want the cockroaches to go extinct too. Do you??" 😂
