Chinchex is a bit new in SG, but i heard they are really popular in HK. I’ve been using it for few months, I followed the instructions on their website and watched tutorial video, it was really helpful and easy to use. The price is absolutely affordable, save me heaps of money from finding pest control . i saw it on amazon too w w w.amazon.sg/Chinchex-Bed-bugs-Insecticide/dp/B082TVPHPG/ref=sr_1_1?keywords=chinchex&qid=1579660063&s=gate way&sr=8-1
