No effect is seen. Review on Hit Spray

Hello friends I want to share my opinions on this spray for killing insects. Our homes are surrounded by many insects which are very harmful and make us fall ill. Many people suffer with the insects and my friend adviced me to bring a hit spray to kill the cockroaches and insects. I have started using it and I noticed no effect on the insects. The application is easy just spray the hit in the holes where the insects and cockroaches roam around but the thing is that the insects after spraying this just faint and get unconscious and after some time they again roam around. There will be no effect on them and it is not useful. Many people without covering their nose starts spraying it around it is not good and it is very harmful. I have suffered alot with its smell and I feel suffocation with this. This is not at all useful and many other ways are there to kill the insects in safe way for the human body. Better stay away from this hit spray. Thank you guys
