this is perhaps simplest way to get rid of mosquitoes .
1. camphor. 50 grams .(as shown in photo)
It should last for a month or more.
take any small bowl , put one camphor tablet in it. fill it with water .
normal water will do.
put an any corner of your room.
you can see immediate effect .if there were any mosquitoes they will go away.
to make more effective,crush camphor slightly.
if room is big, use two bowls with same process.
you can change water after 2 days. use old water it to wipe floor .
I hope this project reaches poor people in asia and africa.
If you don't get in small sizes, try breaking it in capsule size to avoid wastage .
