Summary
House flies are a general annoyance to homeowners and carry the potential for transmitting harmful pathogens. This report covers the method of using fly screens to prevent house flies from entering the house and becoming a pest. The outlined method for testing fly screens would be to place them in isolation with the exit being through a wire mesh with varying wire thickness and gaps. Pulling data from a similar experiment (Busvine, 1965), we can assume that 10 wires per linear inch combined with a wire thickness of 0.274 mm and gap of 2.17mm would stop all flies from entering the home. The investigated solution satisfies the constraints of ethics, environmental/ safety laws, functionality, practicality and affordability.

There should be little to no house flies occupying the home at any point in time and if there are house flies the population should not be considered high enough to be viewed as an ‘annoyance’ or pose a possible health threat. The health problem caused by house flies should be neutralised in that there is no possibility that they land on and contaminate food or food preparation areas. Another performance criteria is that no secondary problem should be created by the solution
Constraints
The proposed solution should be limited by the following constraints:
• The solution should be cost effective so homeowners with a wide range of incomes can apply to their homes.
• Environmental and safety laws should be satisfied
• It should be functional and be able to work always during day and night
• The solution should be practical and easy to use or install
• The ecosystem should not become unbalanced by this …show more content…
The found solution of fly screens is in theory an effective method of achieving this goal. From test results taken from other sources (Busvine, 1965), we can draw the conclusion that well-placed fly screens at windows, doors and other openings in a home would successfully prevent house flies from entering a home. This solves the problem of possible contamination of food and creating breeding grounds inside a home. As house flies are more prevalent in summer than winter this means that windows and doors may be left open for air flow and ventilation without worrying about uninvited house flies. Other constraints that are satisfied by this solution are environmental/safety laws and ethics. Unlike chemical solutions to this problem, no harm will come to any living organism and there will be no unintended consequences like poisoning/harming a house pet. As there will be no dead flies, the secondary consequence of decomposing bodies attracting rodents and cockroaches will not
