    Cockroach is an insect which consumes wide ranges of food and it can cause different kinds of problems such as health problem, economic problems. Cockroach has lived many centuries on the earth and caused many dangerous conditions, starting from consuming rotting garbage to other different kind of food. For these problems starting from manually to scientifically, partial solutions were founded including using different chemicals that used to ride and kill it. In more the anti -cockroach powder with optimum active ingredient and attractant must be combined in order to solve the problem more from the problem was solved before, special proper mixing ratio of ingredients, proper attractant and active ingredients combination was our main issue. The cockroach killing powder was produced by combining boric acid, silica gel and peanut seed powder as attractant. The grinding, drying and mixing process was takes place. The sample could kill cockroach fast and was easy to use, proper cost and no harm to human and for animal. For the production of anti- cockroach powder, the material selection, characterization of those raw materials starting from their physical properties to chemical properties, the impacts of the chemicals on cockroach with and without attractant and the proper sampling and experimental designing for the production of the anti-cockroach powder were investigated. The experimental results were recorded with necessary time interval and the performance of each sample was compared with one another The obtained results indicated that the boric acid powder also has very great dehydrating impacts with different points of mixing ratio. Relatively in all aspects, time of attraction, cost of the sample and the impacts on the cockroach, silica gel (20%) and peanut seed(70%) mixture more than boric acid and peanut seed mixture. From the economic point of view, the rate of return on investment provides 26.5% and the payback period is 2 years. Moreover, there is a positive value for the net present worth
