Guys since I am in hostel after this winter the mosquitos are feeling like taking revenge upon me so one night when I was feeling sick and these mosquitos started to murmuring into my ears then I went to the room which is front of my room and asked for coil or something which can prevent the mosquitos. He handed me a fast card and that worked very effective and protect me from that mosquitos. The next day I went to a shop and ask for a fast card and he gave me all out flash guard.
Effectiveness:
Friends that night I couldn’t sleep well. This is not effective
Don’t use it if you wanna sleep at night.
