Oops!! What I meant was putting 4-5 spoonful of Phenyl in half a bucket of water (We have a small 10 liter bucket kept for things like washing or mopping up floors etc). So pour at least 5 liters of phenyl water. @Naughty, I think you should try water bottle and phenyl water idea separately so that we know if both methods are equally effective or one more than the other. Just asking so that if water bottle method is as effective, I will try to give it a try as well instead of my tried and tested formula of phenyl water.
