lcho & chongho, which pest control company did you engaged & how much did they charged? I e-mailed to some pest control & the lowest I got was $380 nett, but I didn't engage as I want to try to get rid by myself.
What I did was, I wrapped the queen size mattress with the black garbage bag as the mattress encasement was exp. tape with the clear scotape, it was not easily as darn heavy, so next time buy mattress, don't buy heavy one!
Before you tape the closing, add some Diatomaceous Earth into it and tape it, ensure that there's no hole as you don't want those bb to escape. I used PC-CIDE spray which brought from NTUC, but i didn't spray but use brush to brush on the bed frame, as for the bed leg i use cooking oil to prevent bb to crawl. I use hot boiling water to wash the bedsheet, pillow case & bolster case. Next, I mop the wall & floor with hot boiling water, you can add dettol into the water. Even till now I still use hot boiling water to mop the floor.
As leng leng mentioned that bb hate EO, I drop lavendar oil onto the bedsheet not too much lah, a few drop will do. The first time I drop about 7 or 9 drop, my hubby cannot stand it as too strong that he went to the living room & sleep.
Ladies, gotta be hardworking dealing those bb, i often woke up at 1am & 4am to catch bb. It was stress but no choice, I don't want my toddler to kena it.
