The mosquito control technique but instead of using Lemon Fresh Joy, I used Harimau Kuat Lemon flavoured dish wash liquid (yellow bottle and about RM2.80) and..... it actually works. It's cheap and non poisonous like Ridsect of Fumakilla and the others.
Finally, found this simple home tip:-
You have a lot of mosquitoes in your bedroom? Try this.
Mosquito Treatment: So you don't like those pesky mosquitoes. Here's a tip that was given at a recent gardening forum. Put some water in a white dinner plate and add a couple drops of Lemon Fr R. Set the dish on your porch, patio, picnic table, park bench, or other outdoor area. Not sure what attracts them, the lemon smell, the white plate colour, or what.
BUT ... mosquitoes flock to it, and drop dead shortly after drinking the Lemon Fresh Joy/water mixture, and usually within about 10 feet
of the plate.
TRY IT--- it works just superb! It may seem trivial, but it may also help to control mosquitoes around your home, (especially in areas where the West Nile virus is reaching epidemic proportions in mosquitoes, birds and humans).
