I heard about all out flash guard . many people said that it works very well so I bought it .in all out flash guard there is a peice of paper , we need to burn it from one corner .
I found that after using this mosquitos are become unconcious , it is a small peice of paper which burn in two minutes. after that mosquitos again wake up and start biting .
so I thought that it is just a waste of money because it is not long lasting . and its smoke is harmful for our health that causes many harmful diseases.
