Bangalore weather may be heaven for Cockraoches and I found 2 years back when I moved to a rented house. for 2 full years I was troubled by cockraches... no area in house was left that I could not see roaches... It use to be humilating experience opening my laptop bag in the office and finding cockroaches jumping out of my bagpack and also from the laptop.
After reading some reviews I called up PCI, negotiated the rate though it was more (2200 Rs) It was still cheaper as compared to insect sprays that use to finish in a week plus the time.
I got the first application done on 30th Jan, it needed a lot of clean up for the next 3-4 days as lot of cockroaches were found dead. Since than till today I have not found a single cockroach at home, they came and did their 2 and 3rd round of job.
I am pretty happy with the effect and service from PCI. They use some type of injection, I have taken photographs of those. During the first application they use some Bayer product and after that for each visit they use their own product.
