We have been living with these annoying little pests for almost a month now. we have tried everything, from filling up cracks in our tiled walls (the grouting seems to have left small holes where the bugs hide/ breed) to encasing our mattresses to fumigating our room.
and they are still there!!? we have already complained to our agency to inform the landlord regarding the walls as it is where it came from. but they said that it's about the structure/material of the building so it isn't the concern of the landlord and adviced us to use bleach & water to wipe the walls with--ya, as if that will help! those pests will surely comeback after sometime!

Pest control service will cost us a lot so am trying not to opt for that

pls. advice as we are slowly being eaten alive
