Identification:
Fruit flies are small, brownish flies often found around decaying or overripe fruit. They are attracted to sugary and fermenting substances, making them common in kitchens, trash cans, and recycling bins.

Health Risks:
Though they don’t bite or spread diseases directly, fruit flies can contaminate food with bacteria, leading to foodborne illnesses.

Extermination:
To control fruit flies, eliminate their breeding sources by regularly disposing of overripe fruit, cleaning up spills and crumbs, and keeping trash bins clean. Apple cider vinegar traps can be effective in catching fruit flies.

15. Brown Marmorated Stink Bugs (Nymphs)
