Which method is NOT effective in controlling flies?

Ignoring the infested area is not an effective method for controlling flies because it allows the problem to persist and potentially worsen. Flies are attracted to areas with available food sources, moisture, and breeding sites; neglecting these areas can lead to an increase in fly populations. Effective fly management requires proactive measures to address the conditions that attract flies and support their reproduction.

In contrast, eliminating sources of food, using bait traps, and employing exclusion methods are all proactive strategies aimed at reducing fly populations. Eliminating food sources diminishes the attraction for flies, while bait traps can capture adult flies, reducing their numbers. Exclusion methods, such as sealing openings and using screens, prevent flies from entering an area, further contributing to effective control.
