mosquito

Q: Can we use electric shock bats to get rid of mosquitos. It's an equipment which is moved in air if mosquitos touches it, they get killed by electric shock and sometimes they get burned. We tried using mosquito coils etc, but they become resistant to all these. In our area, diseases are common like malaria, etc caused by mosquitos.

Q: There are some tools available in the market (of the shape of a racket or other types) that are used to kill mosquitoes. Some sort of potential difference/ short circuit type of phenomena takes place and the insect gets killed with a spark like sound. Is it permissible to kill an insect in this manner by giving it current?
