My home has the same problem, I tried to use diluted bleach + dry cloth to wipe on the wall surface. It works for a few weeks to a few months, but later on they appear again... I think the ventilation in my home is bad, especially after turning on air-con then turn off, it is wet inside the house... in winter, they disappear...
If you want to kill them one by one without making dirty your wall, you can use wet tissue to kill them, they will stick to the wet tissue and won't damage your wall...
But i have no idea how to kill them forever............
