Introduction
One of the problems in our society today is the pests. These pests can be classified into two – the good and the bad. Good because some pests help the people in their problems while bad because most of them give problems to people. One of these pests that do us no good are the blattaria, or commonly known as cockroaches. One of the solutions for this is the cockroach killer. It is essential in the maintenance of the cleanliness of our environment. Cockroach killers such as Baygon and Aerosol have been proven to kill the cockroach but it is available in a very high amount that’s why people choose to kill cockroaches manually rather than using expensive products to kill them. The people who do not have enough budget for this just let the cockroaches invade their house, not literally but invade by transferring to them the sicknesses they got from the place they come from.
We come up with the idea on making a cockroach killer that is effective, not expensive and eco-friendly. We will try to get the extract of the San Francisco leaves, also known as codiaeum variegatum to drop it to a cockroach to see if it is effective. It is a way for

    The case study, “Riding the Waves Together: A Successful Partnership”, examines the journey of Surf Life Saving New Zealand (SLSNZ) and their struggle to secure sustainable funding in a competitive non-profit industry whilst continuing to stand for their mission to reduce water related injuries and fatalities in New Zealand. The case study examines corporate sponsor and partnership as one solution in addressing the issue and specifically highlights their agreement with Deutsche Post owned DHL, a globally recognised logistics and transportation company. It addresses the crucial parts of forming a partnership and how the two organisations failed to build significant frameworks to maintain a sustainable relationship, especially as it was formed due to both parties concluding that “it made sense”. However, they were able to benefit from DHL through funding their club houses and to update their facilities and equipment. It also provided reasonable levels of funding towards the beach education program launched as a result of this social partnership. DHL were also able to benefit via branding SLSNZ community days, marketing through their schooling programs and gaining access their stakeholders. SLSNZ have been providing life saving services for over 100…

Ok, you are getting very upset with this condition, and you try to get rid of them by using common insects killer spray. It might work, but it is temporarily. What makes you more surprised is their ‘counter attack’, in which they can spread throughout the house and sting you or any of your family members.…

    Roaches and other pest seem to be immune to most pesticides nowadays. In the past few years I have notice that regardless how much you bomb, spray or put out traps they always come back, sometimes with a vengeance. In most communities, mainly apartment complexes, management hire exterminators for preventative measures. But in most cases it’s already too late for that. In recent years there have been studies performed to see why this is and what can be done to fix this ongoing problem.…
