Flies can be a nuisance when buzzing around your premise, particularly if in large numbers. However, some species of fly also pose health risks to humans. House flies transmit a wide range of diseases including salmonella, dysentery, tuberculosis, cholera and parasitic worms. In India, there is a high risk of disease transmission through flies. During emergency situations, when hygiene conditions are less than optimal, flies often are the main reason for cholera and dysentery epidemics. But even under normal conditions, children and elderly are at a greater risk of conducting more common diseases such as salmonella food poisoning from fly contaminated food.
Flies spread diseases because of their breeding and feeding habits. Bacteria from where the fly usually feed on would get stuck on their mouth parts and footpads eventually spreading onto places they land on. Imagine if it’s exposed food that you are about to eat.
The best way to repel flies is through simple, preventive measures. Flies prefer warm temperatures and are most active from late spring to early autumn. In order to best repel flies during this time, limit access to your home as much as possible, keeping doors and windows closed. You may also choose to screen windows, doors and vents. Keep garbage cans clean and securely closed. Keeping surfaces clean will make your home less appealing to flies. For best results, contact a pest control professional to discuss extermination options.
