1. What Are Blow Flies?
Blow flies, scientifically known as Calliphoridae, closely resemble common house flies but are slightly larger, often exhibiting a metallic sheen. These flies, including blue bottle flies, green bottle flies, and cluster flies, share similar feeding and breeding habits with house flies, making them common household pests.
1.1 What Do Blow Flies Look Like?
Metallic Blow Fly
Blow flies are members of the insect order Diptera. Adult blow flies typically measure about 1/3″ to 2/5″ in length and display metallic colors such as black, blue, or green. Their larvae, known as maggots, appear as tiny, pale-white worms. These flies are easily identifiable due to their distinct buzzing sound and metallic appearance.
1.2 Where Do Blow Flies Live?
Blow flies are cosmopolitan, inhabiting diverse geographic regions worldwide. They thrive in temperate to tropical climates with ample loose, damp soil and decaying organic matter, which serves as a breeding ground and food source for their larvae. Warm, humid conditions are particularly conducive to their proliferation.
2. Understanding the Origins of Blow Flies
Where do blow flies come from? They typically breed outdoors before infiltrating homes in search of food sources like rotting produce or decaying meat. Their presence indoors often indicates a nearby attractant. Blow flies may also seek refuge inside homes during the fall to overwinter, becoming active again in the spring.
2.1 What Are the Habits of Blow Flies?
Adult blow flies exhibit a broad dietary range, consuming garbage, decaying vegetation, and other decomposing materials. However, the larvae of most blow fly species are scavengers, primarily feeding on decaying animal carcasses or feces. Adult female blow flies lay their eggs on dead animals, providing sustenance for their developing larvae.
2.2 How Many Eggs Do Blow Flies Lay?
Female blow flies are prolific reproducers, capable of laying 200 to 300 eggs on the flesh of dead or wounded animals. These eggs hatch rapidly, sometimes within hours or up to a few days, depending on environmental conditions.
2.3 What Attracts Blow Flies to Your Yard?
Blow flies are drawn to a variety of organic materials, including garbage, compost, animal feces, and spoiled meat. Eliminating these attractants through regular cleanup is essential for preventing blow fly infestations. Open wounds on pets also make them vulnerable to female blow flies laying eggs.
3. Blow Flies Indoors: Causes and Concerns
3.1 What Causes Blow Flies Inside the House?
Given their preference for decaying organic matter, blow flies are predominantly found outdoors. Indoor activity suggests a nearby source of rot. This could be anything from forgotten fruit in a bowl to a more serious issue like a dead animal in the walls.
3.2 Are Blow Flies Dangerous to Humans and Animals?
Blow flies are not known to bite humans but can transmit bacteria and germs. They pose a greater risk to animals, particularly if they lay eggs in open wounds. The feeding larvae can exacerbate these wounds, leading to severe illness or even death if left untreated. Female blow flies may also deposit eggs in an animal’s eyes, ears, or nose.
4. Delving Into the Blow Fly Life Cycle
Blow Fly Life Cycle
Blow flies undergo complete metamorphosis, progressing through egg, larva (maggot), pupa, and adult stages. They typically develop through three larval instars.
4.1 Stages of Development
After a female blow fly lays eggs in a carcass, wound, or orifice, the first-stage larvae hatch within 24 to 48 hours. These larvae develop through second and third stages before entering the pupal stage and eventually emerging as adults.
4.2 Duration of the Life Cycle
The complete blow fly life cycle, from egg to adult, typically takes two to three weeks, with most adults living for two weeks to a month. This rapid development underscores the importance of swift intervention to control blow fly populations.
5. Addressing Blow Fly Infestations: Prevention and Removal
5.1 Will Blow Flies Go Away on Their Own?
Blow flies in your yard indicate the presence of attractants such as pet feces, dead rodents, or other decaying organic matter. Without regular maintenance and sanitation, blow flies will continue breeding and increasing their populations, alongside other pests like ants and cockroaches.
5.2 Overwintering and Hidden Infestations
Blow flies entering homes in the fall seek sheltered areas to overwinter. They become active again on warm days, similar to cluster flies. A persistent indoor presence may indicate a dead rodent in a wall or crawl space, necessitating removal of the carcass to eliminate the infestation.
6. Effective Strategies for Blow Fly Control

7. Advanced Strategies for Blow Fly Management
7.1 Understanding Blow Fly Behavior
To effectively manage blow flies, understanding their behavior is crucial. Blow flies are highly attracted to the scent of decaying matter, which they can detect from significant distances. This strong olfactory sense guides them to potential breeding sites, making sanitation practices even more critical.
7.2 Targeted Sanitation Practices
While general cleanliness is important, targeted sanitation can significantly reduce blow fly populations.
- Compost Management: Ensure compost piles are properly maintained. Turning the pile regularly and burying fresh waste can reduce odors that attract blow flies.
- Pet Waste Disposal: Promptly dispose of pet waste in sealed bags. Consider using enzymatic cleaners to break down organic matter and eliminate odors.
- Garbage Bins: Use garbage bins with tight-fitting lids and clean them regularly with disinfectant to prevent odor buildup.
7.3 Exclusion Techniques
Preventing blow flies from entering your home is a proactive approach to management.
- Window and Door Screens: Ensure all screens are intact and properly fitted. Repair any tears or gaps to prevent entry.
- Sealing Entry Points: Seal cracks and crevices in foundations, walls, and around pipes to eliminate potential entry points.
- Door Sweeps: Install door sweeps on exterior doors to prevent flies from entering under the door.
7.4 Trapping Strategies
Trapping can be an effective supplemental method for reducing blow fly populations.
- DIY Fly Traps: Create homemade fly traps using a plastic bottle, sugar, water, and vinegar. The sweet mixture attracts flies, while the vinegar helps trap them.
- Commercial Fly Traps: Utilize commercial fly traps that use pheromones or other attractants to lure and capture flies.
- Placement: Place traps strategically near potential entry points or areas with high fly activity.
7.5 Biological Control Methods
Biological control methods involve using natural predators or parasites to control blow fly populations.
- Beneficial Insects: Introduce beneficial insects like parasitic wasps that prey on blow fly larvae.
- Nematodes: Apply nematodes to soil in areas where blow flies breed. These microscopic worms parasitize fly larvae, reducing their numbers.
7.6 Professional Pest Control Services
For severe or persistent infestations, professional pest control services may be necessary.
- Inspection: A professional can conduct a thorough inspection to identify breeding sites and attractants.
- Treatment: Professionals have access to specialized treatments and techniques that are not available to the general public.
- Prevention: They can also provide recommendations for long-term prevention strategies.
