Too many house-flies are coming into people’s homes during the summer when they have their doors and windows open. This is a problem for the people living in these homes as house-flies carry diseases that they transmit onto food around the home. We need to come up with a solution that decreases the number of house-flies coming into the home while allowing people to keep their doors open. After considering numerous ideas I concluded that the best way to do this is via a eugenol based fly spray. Due to tests done by Dr Sinthusiri we have evidence that suggests house-flies will move away from areas that have eugenol sprayed into them. To make it non-harmful and easy to install, the eugenol will be dispersed in automatic canisters set to …show more content…
To conduct this experiment Dr Sinthusiri made with two sections separated by a wooden partition with a hole in the centre. 100 house-flies were released into section B and then sprayed with a crude extract of Tulsi leaves . The movement of flies was recorded every hour for 3 hours. The experiment was repeated for 10 days in June 2008 . The results can be seen in Table 1. This shows that the number of flies did decrease with the introduction of the Tulsi leaf spray. The decrease in the Number of House-flies in section B is shown on Figure 1. The experiment was then done with pure eugenol. And there is a significant increase in the number of flies leaving after the first hour as shown on Table 2. This results in a much steeper gradient in Figure 2 illustrating the effectiveness of eugenol. While pure eugenol is likely not to be the final product, other substances such as lavender oil can be enriched with it causing an effective deterrent to flies. Eugenol is derived from Syzygium aromaticum which is commonly known as Clove . The process of extracting eugenol from cloves is a relatively simple process that could be done on an industrial scale as shown in Dr Antic’s method . Typically, eugenol sprays are made up of 60% eugenol. While there are potential negative side effects if large quantities are ingested, the amount of eugenol required is unlikely to be consumed. However, as a safety precaution, I suggest putting it in timed canisters that release a spray of 4.90 g per hour . This will mean that the amount of eugenol will never reach toxic
