1. Understanding the Fly Problem

Before diving into solutions, let’s understand why flies are such a nuisance, especially in aviation-heavy areas like Daytona Beach, FL.

1.1. Why Are Flies Attracted to Humans and Homes?

Flies are attracted to a variety of things that we often have around our homes and outdoor spaces. Understanding these attractants is key to managing fly populations effectively.

Food Sources: Flies are opportunistic feeders and are drawn to readily available food sources. This includes uncovered food, spills, and even crumbs left on surfaces.
Garbage and Waste: Open or poorly sealed garbage bins are a major attractant. Flies are drawn to the decaying organic matter, which serves as a breeding ground.
Animal Waste: Pet waste left in yards or gardens is another significant attractant. Flies lay eggs in these materials, leading to increased fly populations.
Moisture: Damp environments, such as standing water, leaky pipes, or overwatered plants, provide ideal breeding conditions for many types of flies.
Sweet Scents: Some flies are attracted to sweet or sugary substances, including fruit juices, sodas, and even some perfumes.
Light: Flies are often drawn to light sources, especially at night. This is why you might find them swarming around outdoor lights or trying to get inside through windows.

1.2. The Dangers of Flies: More Than Just a Nuisance

Flies are more than just annoying pests; they can pose significant health risks. Flies can transmit a multitude of pathogens, leading to various diseases. According to the World Health Organization (WHO), flies can carry over 100 different pathogens that can cause diseases in humans and animals. These include bacteria, viruses, and parasites.

Disease Transmission: Flies can transmit diseases such as typhoid fever, cholera, dysentery, and gastroenteritis. They pick up these pathogens on their bodies and legs as they feed on waste, decaying matter, and garbage.
Contamination of Food: Flies often land on food, contaminating it with the pathogens they carry. This can lead to food poisoning and other gastrointestinal illnesses.
Allergic Reactions: Some people are allergic to flies or their waste products. Exposure can cause skin irritation, respiratory issues, and other allergic reactions.
Myiasis: Certain types of flies can cause myiasis, a condition where fly larvae infest living tissue. This can lead to serious health complications if not treated promptly.

1.3. Common Types of Flies and Their Behaviors

Identifying the type of fly you’re dealing with can help you tailor your control methods.

Fly Type	Characteristics	Behavior
House Flies	Grayish, about ¼ inch long, with four dark stripes on the thorax.	Attracted to garbage, decaying organic matter, and food waste. Common in homes and around buildings.
Fruit Flies	Small, brownish, about ⅛ inch long, with red eyes.	Attracted to overripe fruits, vegetables, and fermented liquids. Common in kitchens and pantries.
Drain Flies	Small, dark, and fuzzy, about ⅛ inch long, with rounded wings.	Breed in stagnant water and organic matter in drains, sewers, and septic tanks.
Blow Flies	Metallic blue or green, larger than house flies, about ½ inch long.	Attracted to carrion (dead animals), garbage, and decaying meat.
Horse Flies	Large, gray or brown, with painful bites.	Common in rural areas and near livestock. Females require blood meals.
Stable Flies	Similar in size to house flies but with piercing mouthparts for biting.	Bite animals and humans, often around the ankles. Common near livestock and stables.
Cluster Flies	Larger than house flies, with golden hairs on the thorax.	Overwinter in buildings and emerge in large numbers during warm weather.
Phorid Flies (Humpbacked Flies)	Tiny, yellowish-brown to black, with a distinctive humpbacked appearance.	Attracted to decaying organic matter, sewage, and damp environments. Can breed in drains and damp soil.

2. Citronella Candles: An Overview

Citronella candles have been a popular choice for repelling insects, including flies, for many years. The key ingredient, citronella oil, is derived from citronella grass (Cymbopogon nardus or Cymbopogon winterianus), a plant known for its insect-repelling properties.

2.1. What is Citronella Oil?
