Hello friends, the product named as ’kala hit’ is really dangerous for the health and for babies it causes more danger. for certain time I also used this product and I am not completely sure whether it kills all the mosquitoes or not but it spread them for some time and after some time all mosquitoes they come again also its fragrance is really bad and I bet you can not stay where ever it is spread . please do not use such product. But if you are using this product you will see the consequences on you and on your families health. It can cause skin itching / skin related problem / breathing problems. It will be good if you use natural product or mosquito net.
