One of the Do It Yourself(DIY) project I did recently came very handy for the purpose it was aimed for. Prior to now, I used to have issues with buying road side insecticides due to their ineffectiveness in killing both crawling and flying insects specifically mosquitoes and cockroaches. I was seriously disgusted with this development, that I decided to cease the use of any of them. Fortunately, I stumbled on article on how one can make insecticide that would be worth the time, money and resources in doing so. Subsequently, I decided to give it a shot.
All you need is kerosine, water and bathing soap. Pour your water into plastic container, and leather your bathing soap into it until it is foaming. Add you your kerosine to the water in same proportion. Stir them altogether and turn into a different container, preferably one with spraying aerosol noozle.
With this DIY you have you insecticide ready for killing of insects.
