Flies generally prefer light environments as they are positively phototactic, meaning they are attracted to light. This is why flies are often seen gathering around windows or illuminated areas during the day. Utilizing this behavior, light traps can be used to attract and capture flies effectively in darker rooms. However, at night, they might seek darker spaces to hide and rest. Keeping environments well-lit during the day can help in managing and monitoring fly activity.
